The National Hurricane Center has issued updated wind speed probability graphics for Potential Tropical Cyclone One, with the latest data released on Wednesday, June 17, 2026, at 9:21 a.m. GMT.
The graphics show the probability of 34-knot wind speeds affecting various areas over a 120-hour forecast period. Forecasters will continue to monitor the storm system as it develops.
Residents in potentially affected coastal regions are encouraged to stay informed and follow guidance from local emergency management officials as the situation evolves.
A developing tropical system is tracking northeastward along the middle Texas coast and is raising serious concerns about life-threatening flooding across portions of the southeastern United States.
According to a 4:00 AM CDT update issued Wednesday, June 17, the center of Potential Tropical Cyclone One was positioned near latitude 28.0 north, longitude 96.7 west. The storm was moving to the northeast at approximately 6 miles per hour.
The system’s minimum central pressure was recorded at 1003 millibars, with maximum sustained winds of roughly 30 mph. While the winds remain relatively modest at this stage, forecasters are emphasizing the flooding threat as the primary danger for communities in the storm’s path.
Residents across the southeastern United States are urged to monitor updates from weather officials and be prepared for rapidly changing conditions as the system continues to move inland.
The National Hurricane Center in Miami issued Forecast Advisory Number 4 for Potential Tropical Cyclone One at 9:00 a.m. UTC on Wednesday, June 17, 2026.
As of that advisory, the center of the system was located near 28.0 degrees north latitude and 96.7 degrees west longitude, with the position considered accurate within 40 nautical miles. The storm was moving toward the northeast at approximately 5 knots, or about 6 miles per hour.
The system had a minimum central pressure of 1003 millibars at the time of the advisory. Maximum sustained winds were estimated at 25 knots, with gusts reaching up to 35 knots.
Forecasters expected the system to strengthen into a tropical cyclone by 6:00 p.m. UTC on Wednesday, with maximum sustained winds increasing to 35 knots and gusts up to 45 knots, placing it near 29.1 degrees north and 95.2 degrees west.
By early Thursday morning, June 18, the system was forecast to weaken into a post-tropical remnant low with maximum sustained winds dropping back to 25 knots. The storm was expected to fully dissipate by Wednesday evening, June 18.
The advisory was issued by forecaster Berg. Ships within 300 miles of the system’s center were asked to submit reports every three hours. The next full advisory was scheduled for 3:00 p.m. UTC on Wednesday.
A disorganized low pressure system hovering near the middle Texas coastline is showing little sign of developing into a tropical cyclone, according to a 4:00 AM CDT Wednesday forecast discussion issued by the National Hurricane Center.
Offshore buoy readings confirm the system’s maximum sustained winds are holding at 25 knots. While a band of deep thunderstorm activity has developed over the northwestern Gulf of Mexico since the previous advisory, powerful westerly wind shear — blowing at 25 to 30 knots — has displaced that convection more than 120 nautical miles to the east and southeast of the low’s center. Because of this separation, forecasters at the Tropical Analysis and Forecast Branch rated the system as “Too Weak To Classify,” meaning it lacks the organized storm structure required to be officially named a tropical cyclone.
The system is currently drifting to the northeast at about 5 knots. As low- to mid-level winds strengthen from the southwest and a weather trough approaches from the northwest, the system is expected to pick up speed throughout Wednesday. The low’s center is forecast to straddle the Texas coastline for much of the day before pushing inland over eastern Texas or Louisiana by Wednesday night.
Forecasters say the chances of this system achieving tropical cyclone status appear to be fading. With the center not expected to spend enough time over open Gulf waters and wind shear remaining strong through the next 12 hours, organization is unlikely before the system moves ashore. Even so, winds could still strengthen somewhat in areas well east of the center during the day, and the official forecast still shows a peak of 35 knots at the 12-hour mark. All major global weather models then show the system breaking apart into a trough over Louisiana by Wednesday night, with the official forecast classifying it as a remnant low at 24 hours — though complete dissipation before that point is also possible.
Looking further ahead, forecasters are watching the leftover low-level energy as it tracks eastward across the southeastern United States on Thursday and Friday. The European, Canadian, and United Kingdom weather models each suggest a new low pressure system could redevelop — particularly if the remnant circulation moves back offshore over the western Atlantic. Forecasters say they will continue monitoring model trends for any potential tropical development over the western Atlantic later this week or into the weekend.
Regardless of whether the system ever achieves tropical cyclone status, the National Hurricane Center is emphasizing that heavy rainfall and life-threatening flash flooding remain the primary dangers.
Key Hazards:
Life-threatening flash flooding and urban flooding are expected through Thursday across southern Louisiana, southern Mississippi, southern Alabama, southwestern Georgia, and the Florida Panhandle, with possible flooding also near the upper Texas coast. Ongoing heavy rain could keep the flood threat going into the weekend.
Tropical-storm-force winds are expected along the Louisiana coast between Sabine Pass and Morgan City, where a Tropical Storm Warning is currently in effect.
Minor to moderate coastal flooding is also anticipated along portions of the upper Texas and Louisiana shorelines on Wednesday.
This forecast discussion was prepared by Forecaster Berg at the National Hurricane Center.
The National Hurricane Center in Miami issued its fourth wind speed probability update Wednesday morning for Potential Tropical Cyclone One, a developing system being closely watched in the Gulf of Mexico.
As of 9 a.m. Coordinated Universal Time on Wednesday, June 17, 2026, the center of the system was positioned near latitude 28.0 North and longitude 96.7 West, with maximum sustained winds clocking in at approximately 25 knots — roughly 30 miles per hour or 45 kilometers per hour.
Forecasters are calculating the chances that several Gulf Coast communities could experience sustained wind speeds reaching tropical storm force or higher over the coming five days. The probability data covers wind thresholds of 39 mph, 58 mph, and 74 mph.
Among the locations being monitored, Galveston, Texas carries an 18 percent chance of seeing at least 39 mph winds during the first 12-hour forecast period, with a cumulative probability of 20 percent through the full five-day outlook. Matagorda, Texas shows an 11 percent onset probability for the same wind threshold in that opening period.
Cameron, Louisiana has a 10 percent cumulative probability of reaching tropical storm-force winds, while Lake Charles carries a 3 percent cumulative chance. Port O’Connor and High Island, Texas are also included in the tracking data with lower probability figures.
The forecast was prepared by forecaster Berg at the National Hurricane Center.

Residents in those areas are urged to monitor updates closely and follow guidance from local emergency management officials.
The National Hurricane Center is tracking a disorganized weather disturbance that is beginning to push into the northwestern Gulf of Mexico, and forecasters say it could develop into a tropical storm as early as Wednesday.
As of 10:00 PM CDT Tuesday, June 16, 2026, the system — designated Potential Tropical Cyclone One — had sustained winds of around 25 knots, or about 30 miles per hour. Forecasters noted that strong westerly wind shear is disrupting the storm’s structure, pushing most of the heavy rainfall away from the center of circulation. Because of this, the system has not yet qualified as a full tropical cyclone.
Despite its relatively weak winds, the storm is expected to move northeastward, running just off the Texas coastline before likely coming back onshore late Wednesday or Wednesday night. The National Hurricane Center says the system could gain some strength while it is briefly over the warm Gulf waters, but ongoing wind shear is expected to limit how powerful it becomes before landfall.
The official forecast calls for the system to reach tropical storm strength on Wednesday, with maximum winds around 35 to 40 knots before weakening rapidly once inland. Forecasters expect the system to dissipate entirely by Friday.
Regardless of whether it officially becomes a named tropical storm, forecasters are emphasizing that heavy rainfall and flash flooding represent the most dangerous threats from this system.
The National Hurricane Center issued the following key warnings:
Life-threatening flash flooding and urban flooding is likely through Thursday across Louisiana and southern Mississippi, with the threat also extending near the Upper Texas coast. Flash flooding is additionally possible across Alabama, Georgia, and the Florida Panhandle through the end of the week, and prolonged rainfall could push the flood threat into the weekend.
A Tropical Storm Warning is in effect along the Louisiana coast from Sabine Pass to Morgan City, where tropical-storm-force winds are expected on Wednesday.
Minor to moderate coastal flooding is also anticipated along parts of the Upper Texas and Louisiana shorelines.
The forecast discussion was issued by forecasters Pasch and Adams at the National Hurricane Center in Miami, Florida.
The National Hurricane Center in Miami issued its third advisory on Potential Tropical Cyclone One early Wednesday morning, tracking a disorganized but developing weather system in the Gulf of Mexico.
As of 3:00 a.m. UTC on Wednesday, June 17, 2026, the center of the system was located near 27.6 degrees north latitude and 97.1 degrees west longitude. Forecasters say the position is accurate within about 40 nautical miles.
The system is currently moving toward the northeast at approximately 5 knots, or roughly 6 miles per hour. It is producing maximum sustained winds of 25 knots — about 29 miles per hour — with gusts reaching up to 35 knots.
The estimated minimum central pressure stands at 1004 millibars. Forecasters note that wind and sea conditions vary significantly from one side of the storm to the other.
Looking ahead, the National Hurricane Center expects the system to reach tropical cyclone status by Wednesday afternoon, with maximum winds climbing to 30 knots. By early Thursday morning, the system is forecast to be inland, with winds increasing to 35 knots and gusts up to 45 knots.
The system is expected to weaken significantly once inland, dropping to 20-knot winds by Thursday afternoon. Forecasters project the system will fully dissipate by early Friday, June 19.
The advisory was prepared by forecasters Pasch and Adams. The next full advisory is scheduled for 9:00 a.m. UTC Wednesday, with an intermediate public advisory expected at 6:00 a.m. UTC. Ships within 300 miles of the storm’s center have been asked to submit reports every three hours.
The National Hurricane Center in Miami issued its third wind speed probability bulletin for Potential Tropical Cyclone One at 3:00 a.m. Coordinated Universal Time on Wednesday, June 17, 2026.
At the time of the bulletin, the center of the storm system was located near latitude 27.6 degrees north and longitude 97.1 degrees west, with maximum sustained winds of approximately 25 knots — equal to about 30 miles per hour or 45 kilometers per hour.

A low-pressure system churning in the Gulf of Mexico is edging closer to tropical storm status, according to the latest forecast discussion issued Tuesday afternoon by the National Hurricane Center in Miami.
As of 4:00 PM CDT Tuesday, the system — currently classified as Potential Tropical Cyclone One — is producing scattered, disorganized thunderstorm activity mostly over water, concentrated in its eastern half. Forecasters noted that the storm’s low-level center has become more clearly defined throughout the day, supported by satellite imagery, surface observations, and dropping air pressure readings. Despite the improvement, the system still falls just short of the criteria needed to be upgraded to a tropical depression, lacking a well-defined center and consistent storm activity. Its current wind intensity is estimated at 25 knots, or about 30 miles per hour.
The system has been drifting slowly to the northeast. Forecasters expect it to move offshore of south Texas Tuesday night before picking up speed along the coast on Wednesday. That acceleration is being driven by a mid-latitude weather trough positioned over the eastern United States. Forecast models show the system tracking very close to the Texas coastline on Wednesday before moving back onshore late Wednesday or Wednesday night. The storm’s circulation is then expected to break down quickly over central Louisiana on Thursday.
There is potential for some strengthening on Wednesday as the system spends time over the warm waters of the Gulf and interacts with upper-level wind patterns. Most forecast models indicate the system could reach tropical storm strength by Wednesday. The official forecast largely mirrors the previous update.
Regardless of whether the system achieves tropical cyclone status, forecasters are warning that dangerous rainfall and life-threatening flash flooding remain the top concerns.
The National Hurricane Center outlined three key hazards associated with the storm:
First, potentially life-threatening flash flooding and urban flooding is considered likely through Thursday across Louisiana and southern Mississippi, with flash flooding also possible near the Upper Texas coast. Additional flash flooding is possible across Alabama, Georgia, and the Florida Panhandle through the end of the week, with prolonged rainfall possibly extending the flood threat into the weekend.
Second, tropical-storm-force winds are expected along the Louisiana coast on Wednesday, from Sabine Pass to Morgan City — an area now under a Tropical Storm Warning.
Third, minor to moderate coastal flooding is anticipated along parts of the Upper Texas and Louisiana coastlines.
The forecast was issued by Forecaster Blake at the National Hurricane Center.
The National Hurricane Center in Miami issued its second wind speed probability bulletin for Potential Tropical Cyclone One at 9 p.m. Coordinated Universal Time on Tuesday, June 16, 2026.
At the time of the advisory, the center of the system was located near latitude 27.3 degrees north and longitude 97.6 degrees west, placing it near the Texas Gulf Coast. Maximum sustained winds were recorded at approximately 25 knots — equivalent to 30 miles per hour or 45 kilometers per hour.
The bulletin outlines the probability of tropical storm-force winds of at least 34 knots (39 mph) reaching several Gulf Coast locations over the next five days. Among the locations with the highest cumulative chances of experiencing those wind speeds are Cameron, Louisiana, with a 21 percent cumulative probability, and Galveston, Texas, also showing a 20 percent cumulative probability.
Other locations listed in the advisory include Lafayette, Louisiana; New Iberia, Louisiana; Fort Polk, Louisiana; Lake Charles, Louisiana; Port Arthur, Texas; Freeport, Texas; High Island, Texas; Matagorda, Texas; and Port O’Connor, Texas. Cumulative wind speed probabilities at those locations ranged from 3 to 13 percent for tropical storm-force winds over the five-day period.
The bulletin did not show any significant probabilities for stronger winds of 50 knots or 64 knots at any of the listed locations.
The advisory was prepared by forecaster Blake at the National Hurricane Center.

MIAMI (AP) — A developing storm system along the Gulf Coast may become the first named tropical storm of the 2026 Atlantic hurricane season, according to the National Hurricane Center.
The storm cluster was positioned Tuesday afternoon roughly 55 miles south-southwest of Corpus Christi, Texas, and threatened to unleash heavy rainfall capable of triggering dangerous flooding across southern states, including Texas and Louisiana.
National Hurricane Center director Michael Brennan said forecasters expect the system to gain strength, potentially reaching tropical storm status by early Wednesday. He noted that coastal communities could face tropical storm conditions this week regardless of whether the system earns an official name.
“The main hazard with these types of systems is largely the flooding from the heavy rainfall,” Brennan said. “And we could see potentially life-threatening flash and urban flooding across the Texas coast eastward into central Mississippi through Thursday. Prolonged rainfall may extend the flood threat into the weekend.”
Forecasters also warned that tornadoes were possible stretching from the upper Texas coast through southern Louisiana, Mississippi, Alabama, and into the Florida Panhandle.
As of Tuesday, the storm’s maximum sustained winds were clocking in at around 30 mph — just under the 39 mph threshold required to be officially classified as a tropical storm. The National Hurricane Center put the odds of the system developing into a tropical cyclone within the next two days at 70%.
Houston, which is set to host a World Cup match between Portugal and the Democratic Republic of the Congo on Wednesday, has been under a flood warning since Monday. The match venue has a covered roof, and officials have not announced any plans to relocate or reschedule the game.
Rainfall totals by Thursday could reach 4 to 8 inches across the affected region, with some isolated coastal areas potentially seeing up to a foot of rain.
A tropical storm watch was already in place from Sargent, Texas, to Morgan City, Louisiana. Dangerous rip currents are expected along Gulf Coast beaches over the next several days due to rough surf.
A new weather system is taking shape in the Gulf of Mexico, with the U.S. National Hurricane Center announcing Tuesday that Potential Tropical Cyclone One has formed roughly 65 miles southwest of Corpus Christi, Texas. The storm is raising concerns about severe flash flooding and possible disruptions to a major energy-producing region along the Gulf Coast.
If the system gains enough strength to become a named storm, it would be called Arthur and would mark the first named storm of the 2026 Atlantic hurricane season. As of Tuesday, the storm was producing maximum sustained winds of 30 miles per hour. A tropical storm watch has been put in place for a stretch of the northwestern Gulf Coast running from Sargent, Texas, to Morgan City, Louisiana.
According to the National Hurricane Center, the disturbance is expected to move offshore along the Texas coast Tuesday night or early Wednesday, then travel roughly parallel to the upper Texas coast later Wednesday before pushing back inland over far eastern Texas or southwestern Louisiana late Wednesday or early Thursday.
Regardless of whether the storm intensifies further, forecasters say it is on track to drop between 4 and 8 inches of rain — with some isolated areas potentially seeing up to 12 inches — through Thursday across the Texas coast and much of Louisiana. The NHC also cautioned that a dangerous storm surge could push water into areas that are normally dry.
Texas Governor Greg Abbott declared a disaster for 101 counties in the state on Monday ahead of the storm’s arrival.
The rain is also expected to affect the FIFA World Cup match between Portugal and DR Congo scheduled to take place in Houston on Wednesday. Beyond the sporting event, energy industry experts are keeping a close eye on potential impacts to oil and gas infrastructure throughout the region. Tony Dupont, COO at Earth Science Associates, offered an early assessment, saying the storm “doesn’t look too strong” at this point.
Andrew Polk, a weather risk manager at data consultancy DTN, noted that major oil production sites in the Gulf are currently sitting outside the projected path of tropical storm-force winds. However, he warned that some disruptions could still occur. “There may still be some disruptions, primarily due to the overall impact of helicopter operations which may disrupt and delay crew changes from occurring due to the winds and thunderstorms associated with Potential Tropical Cyclone One,” Polk said in an emailed statement, adding that wave heights are expected to climb to between 7 and 9 feet to the east and south of the storm.
Polk further explained that “the wave impacts primarily disrupt operations in the water with lift boats and/or diving operations,” and said the main concern from the storm will be the total amount of rainfall expected to fall along the Texas and Louisiana coastlines.
The stakes are high for the region’s energy infrastructure. The U.S. Gulf of America federal offshore zone produced close to 2 million barrels of crude oil each day in March, making up roughly 14% of all U.S. crude production. Shell, BP, Chevron, and Occidental are among the biggest deepwater operators working in those waters.
The Gulf Coast refining corridor, which stretches from Corpus Christi to the Mississippi River, handles around half of the entire U.S. refining capacity of 18.4 million barrels per day. The country’s largest refinery — the Saudi Aramco-owned Motiva Enterprises plant in Port Arthur, Texas — processes 730,000 barrels per day on its own. Other significant facilities in the region include Marathon Petroleum’s Galveston Bay plant, ExxonMobil’s Beaumont and Baytown refineries, and ExxonMobil’s Baton Rouge, Louisiana, facility.
Major liquefied natural gas companies, including Cheniere and Venture Global, also operate large facilities along the same coastal stretch.
Weather forecasters have issued updated graphics tracking Potential Tropical Cyclone One, including wind speed probability data covering a five-day forecast window.
The latest wind speed probability graphic was updated Tuesday, June 16, 2026, and shows the chances of 34-knot winds affecting various areas within the storm’s projected path over the next 120 hours.
Residents in coastal communities are encouraged to keep a close eye on the latest forecasts as the system continues to develop. Officials will provide additional updates as the storm’s track and intensity become clearer.

A potentially active weather day is shaping up across the Mid-Atlantic on Thursday as a powerful storm system moves through the Great Lakes and drags a strong cold front toward the region. While some uncertainty remains regarding the exact evolution of the atmosphere, the overall setup is becoming increasingly favorable for severe thunderstorms capable of producing damaging winds.
An upper-level trough will strengthen across the Great Lakes while a deepening area of low pressure tracks into southeastern Canada. In response, very strong southwest winds will develop throughout the atmosphere, transporting increasing heat and humidity into the region during the day Thursday.
The biggest forecast question remains how much instability can develop before thunderstorms arrive. Early morning clouds or showers could limit daytime heating in some locations, while a faster return of moisture and sunshine would allow the atmosphere to become much more unstable. Even if instability remains only modest, we are confident that exceptionally strong wind fields and powerful upper-level dynamics will be more than sufficient to support organized severe thunderstorms.
Wind shear values exceeding 50 knots are forecast across the region, an impressive setup for the middle of June. Combined with strengthening forcing along the approaching cold front, thunderstorms are expected to organize into clusters or line segments capable of producing widespread damaging straight-line winds.
While damaging winds appear to be the primary hazard at this time, the environment will need to be monitored closely for any increase in instability. Should storms become more discrete before evolving into a line, all modes of severe weather, including large hail and even an isolated tornado, could become possible.
Away from the thunderstorms themselves, Thursday is also expected to be unusually windy. Sustained southwest winds of 15 to 25 mph with gusts between 35 and 40 mph are likely throughout the afternoon, making for a very breezy day even before storms develop.
Temperatures will climb into the lower and middle 90s across much of the region, with heat indices reaching the 90s ahead of the approaching front. The combination of hot, humid, and windy conditions will set the stage for potentially intense thunderstorms during the afternoon and evening hours.
While finer details regarding timing and storm intensity will become clearer over the next 24 to 36 hours, residents across Delmarva and the surrounding Mid-Atlantic should closely monitor the latest forecasts. The overall pattern strongly supports the potential for severe weather, with damaging winds currently appearing to be the greatest concern.
The National Hurricane Center has issued updated wind speed probability graphics for a weather system currently being tracked as Potential Tropical Cyclone One.
The graphics, last updated Tuesday, June 16, 2026, show the probability of 34-knot winds — roughly 39 miles per hour — affecting different areas within a five-day forecast window.
Forecasters are closely watching the system as it has the potential to develop further. Residents in coastal areas are encouraged to stay informed and monitor the latest updates from official weather authorities.

A developing tropical weather system is posing a serious flooding threat as it slowly pushes inland, forecasters warned Tuesday morning.
According to the National Hurricane Center, as of 10:00 AM CDT on Tuesday, June 16, the center of Potential Tropical Cyclone One was positioned near coordinates 27.0 degrees north latitude and 98.0 degrees west longitude. The storm was tracking to the northeast at approximately 6 miles per hour.
The system had a minimum central pressure of 1007 millibars and maximum sustained winds of around 30 miles per hour at the time of the advisory.
Despite its relatively modest wind speeds, forecasters are emphasizing that the primary danger from this system is not wind — it is water. Very heavy rainfall and dangerous flash flooding are expected as the storm moves through the region.
Residents in the storm’s path are urged to monitor local emergency management guidance and avoid low-lying areas that may be susceptible to rapid flooding.
The National Hurricane Center in Miami issued its first forecast advisory Tuesday afternoon for Potential Tropical Cyclone One, a developing weather system that could pose a threat to portions of the Gulf Coast.
As of 3:00 p.m. UTC on Tuesday, June 16, 2026, the center of the disturbance was located near 27.0 degrees north latitude and 98.0 degrees west longitude, an area near the Texas-Mexico border region. The position is estimated to be accurate within 60 nautical miles.
The system is currently drifting toward the northeast at about 5 knots, or roughly 6 miles per hour. Maximum sustained winds are currently at 25 knots, with gusts reaching up to 35 knots. The minimum central pressure is estimated at 1007 millibars.
According to the forecast, the system is expected to strengthen into a tropical storm by the morning of June 17, with maximum sustained winds increasing to 35 knots and gusts up to 45 knots. The storm is forecast to continue tracking northeast toward the Louisiana and Texas coast.
By the afternoon of June 18, the system is expected to move inland, with winds weakening to 25 knots. Forecasters predict the storm will fully dissipate by June 19, 2026.
The National Hurricane Center has requested ship reports from vessels within 300 miles of the storm’s current position. The next full advisory was scheduled for 9:00 p.m. UTC Tuesday, with an intermediate advisory expected at 6:00 p.m. UTC. Forecaster Blake issued the advisory.
The National Hurricane Center in Miami issued its first advisory Tuesday morning on Potential Tropical Cyclone One, a weather disturbance that has been tracked for several days as it traveled across the southern Gulf of America and into northeastern Mexico before pushing into southern Texas.
The system, previously identified as AL90, is generating significant rainfall but has not yet developed a well-defined center of circulation. Forecasters say most computer models indicate the system will move back offshore overnight Tuesday, with winds expected to reach tropical storm strength by Wednesday. As a result, Tropical Storm Watches have been put in place for parts of the Upper Texas coast and southwestern Louisiana shoreline — specifically from Sargent, Texas, to Morgan City, Louisiana.
Regardless of whether the disturbance officially becomes a tropical cyclone, forecasters are warning that heavy rain and life-threatening flash flooding remain the most serious dangers. The initial wind intensity has been set at 25 knots, or about 30 miles per hour, based on surface and radar observations.
The storm is currently drifting slowly to the northeast. Forecasters expect it to pick up speed as it interacts with a broad weather trough sitting over the eastern United States. Models suggest the system will hug the Texas coastline Wednesday before moving back onshore late Wednesday or early Thursday. Forecasters project the system will dissipate by early Friday.
Upper-level atmospheric conditions are not particularly favorable for significant strengthening, with notable wind shear and the system’s close proximity to land working against it. However, a jet stream to the north and warm Gulf waters are expected to support some intensification through Wednesday. Due to the shear, the storm is unlikely to take on a classic tropical appearance on satellite imagery — instead, rainfall and winds will be concentrated heavily on the eastern side of the system.
Key hazards forecasters are highlighting include:
Flooding: Potentially life-threatening flash and urban flooding is expected along the Texas coast eastward into central Mississippi through Thursday. If rainfall is prolonged, flood threats could stretch into the weekend. Small stream and minor river flooding is anticipated along the Texas coast into southwestern Louisiana, with isolated pockets of significant river flooding possible in those areas.
Tropical Storm Threat: The system is forecast to strengthen into a tropical storm as it moves along or just off the northwestern Gulf Coast through Wednesday.
Coastal Flooding: Minor to moderate coastal flooding is expected along portions of the Upper Texas and Louisiana coastlines.
This advisory was issued by Forecaster Blake at the National Hurricane Center.
The National Hurricane Center in Miami issued its first wind speed probability advisory for Potential Tropical Cyclone One at 3:00 p.m. Coordinated Universal Time on Tuesday, June 16, 2026.
At the time of the advisory, the center of the system was positioned near latitude 27.0 North, longitude 98.0 West. Maximum sustained winds were estimated at approximately 25 knots — equivalent to 30 miles per hour or 45 kilometers per hour.
The advisory, prepared by Forecaster Blake, outlines the probability of tropical-storm-force winds of at least 34 knots (39 mph), 50-knot winds (58 mph), and hurricane-force winds of 64 knots (74 mph) reaching various locations along the Gulf Coast over the next five days.
Among the locations with notable cumulative probabilities of experiencing at least tropical-storm-force winds are Cameron, Louisiana, with a 25 percent cumulative chance; Galveston, Texas, at 25 percent; and a Gulf forecast grid point near 28.0 North, 95.0 West, carrying a 37 percent cumulative probability — the highest listed in the advisory.
Other areas listed in the probability table include Baton Rouge, Lafayette, Alexandria, New Iberia, and Lake Charles in Louisiana, as well as Port Arthur, Freeport, High Island, Matagorda, Port O’Connor, and Rockport in Texas.
Residents and interests along the Gulf Coast are encouraged to monitor updates from the National Hurricane Center as the system continues to develop.

After a stretch of comfortable weather to start the week, attention is turning to a potentially active weather pattern that could bring strong to severe thunderstorms to portions of the Mid-Atlantic on Thursday afternoon and evening.
We are monitoring a strengthening upper-level trough that will sweep across the Great Lakes and northeastern United States. As this system approaches, a deepening area of low pressure tracking through the eastern Great Lakes will drag a strong cold front toward the region, setting the stage for potentially hazardous weather.
Southerly winds ahead of the approaching front will transport warmer, more humid air northward throughout the day Thursday, allowing instability to build across much of the region. At the same time, increasing winds aloft will create a more favorable environment for organized thunderstorms capable of producing severe weather.
The primary concern at this time appears to be damaging straight-line winds, particularly if storms organize into a fast-moving squall line along the advancing cold front. However, we caution that if instability becomes greater than currently expected or storms develop as isolated cells before forming a line, additional hazards such as large hail and isolated tornadoes could also become possible.
One of the biggest uncertainties remains how much instability can develop before storms arrive. Morning cloud cover and any early-day showers or thunderstorms could limit daytime heating and reduce the overall severe weather threat in some locations. Likewise, the strongest upper-level winds may remain displaced somewhat north of the richest moisture, creating additional uncertainty in the magnitude of the event.
Despite these questions, the overall synoptic pattern is supportive of severe weather, with strengthening wind shear, increasing moisture, and a strong approaching cold front all coming together during the late afternoon and evening hours.
Ahead of the storms, temperatures are expected to climb well into the upper 80s and lower 90s, especially along the Interstate 95 corridor and across the coastal plain away from the immediate shoreline. Combined with increasing humidity, heat index values could approach 100 degrees before thunderstorms develop.
Residents across the Mid-Atlantic, including the Delmarva region, should closely monitor the forecast over the next couple of days as confidence in the exact timing and severity of the threat continues to improve. Forecast adjustments are likely as mesoscale details become better resolved.
Stay weather-aware Thursday afternoon and evening, and be prepared for the potential of rapidly changing conditions if severe thunderstorms develop.

Residents across the Delmarva Peninsula should remain weather-aware today as another round of potentially severe thunderstorms is expected to develop late this afternoon and continue into the evening hours.
The Storm Prediction Center has placed the entire Delmarva region under a Slight Risk (Level 2 of 5) for severe thunderstorms, signaling the potential for scattered storms capable of producing damaging weather.
A cold front approaching from the west, combined with increasing influence from an upper-level disturbance, will provide the ingredients needed for thunderstorm development. While not everyone will see storms, those that do form could quickly become strong to severe.
Note that one of the biggest uncertainties today is storm coverage. A localized area of sinking air aloft may temporarily suppress thunderstorm development across portions of southeastern Pennsylvania, the Philadelphia metro area, and southern New Jersey. However, areas farther north and south of that corridor, including much of Delmarva, could see stronger storm development where instability is able to build.
The primary concern will once again be damaging straight-line winds, fueled by very hot temperatures, abundant low-level moisture, and an atmosphere favorable for powerful downbursts. Some wind gusts could exceed 60 mph, capable of bringing down trees, power lines, and causing localized damage.
An isolated instance of small hail cannot be ruled out, but the overall threat for large hail remains low. Likewise, atmospheric conditions are not particularly favorable for tornado development, making that risk minimal.
Temperatures climbing into the 90s will help fuel strong instability through the afternoon before thunderstorms begin to develop. Some storms may organize into clusters and race eastward across the peninsula through the early evening before gradually weakening after sunset.
Residents are encouraged to closely monitor the latest forecasts throughout the day and have multiple ways to receive weather warnings. If a Severe Thunderstorm Warning is issued for your location, move indoors immediately and stay away from windows until the storm passes.
Emergency personnel and community members conducted damage surveys Friday following a devastating line of severe weather that tore through areas south of Chicago, knocking out electricity for approximately 380,000 utility customers across Illinois and Indiana while causing significant disruptions to regional air travel.
Authorities reported no immediate fatalities or life-threatening injuries resulting from Thursday’s violent weather system.
Local authorities in Merrillville, Indiana, located roughly 33 miles southeast of Chicago, documented widespread destruction throughout their community. Residential structures and commercial buildings sustained severe damage, fallen trees and electrical lines created roadway blockages, and a portion of a local high school’s roofing system was completely destroyed.
Regional emergency response teams assisted local first responders in conducting search operations and evaluating affected neighborhoods, according to municipal officials posting updates on social media platforms. Work crews continued clearing debris from roadways throughout the overnight hours.
The National Weather Service confirmed that at least two additional tornadoes struck communities in the vicinity of Streator, Illinois, and Hebron, Indiana. Social media posts containing photographs and video footage revealed destruction patterns in these locations matching the devastation observed in Merrillville. Weather service meteorologists indicated they will conduct comprehensive damage surveys over the coming days to establish the total number of tornadoes that made ground contact across the affected region.
Emergency response teams in Streator, a manufacturing and agricultural community situated approximately 100 miles southwest of Chicago, also began damage assessment operations. City officials established a reunification facility for displaced community members at the municipal building while the Red Cross activated an emergency shelter.
Streator Mayor Tara Bedei confirmed no fatalities had been documented in her community. “We are incredibly grateful for the safety of our residents and the quick action of emergency personnel,” she said in a statement.
Emergency personnel in Hebron, positioned about 50 miles southeast of Chicago, also maintained operations throughout the night, according to official Facebook communications.
Jennifer Hall was inside her garage in Elkhart, Indiana, when the severe winds and precipitation intensified Thursday evening. Without warning, she reported hearing a tremendous impact and subsequently discovered that a large tree branch had penetrated her rental property’s roof. She deployed containers to collect rainwater entering through the opening.
“I’m just nervous because it’s just been one thing after another,” said Hall, explaining she just had surgery and her husband is out of town.
Electrical service remained disrupted for roughly 235,000 residences and commercial establishments throughout Illinois, including 144,000 customers in Cook County, which encompasses Chicago, based on poweroutage.us data. An additional 144,000 customers experienced power failures across Indiana.
The severe weather system caused flight delays and cancellations at multiple airports Thursday, including facilities in Chicago, Philadelphia and New York. Portions of the Northeast and mid-Atlantic regions also experienced challenging conditions due to elevated temperatures and humidity levels. Friday morning operations at Chicago’s O’Hare International and Midway International airports included 15 canceled flights and approximately 24 delayed departures, representing a small fraction of total scheduled service, according to FlightAware flight monitoring services.
These tornado events followed severe weather systems that moved through Midwest states Wednesday, causing power disruptions, structural damage and flight cancellations.
In Des Moines, Iowa, a 54-year-old man died at a homeless encampment in a park Wednesday after being hit by a tree that “broke apart and fell during strong storms,” police said in a statement. There were no immediate reports of other deaths or injuries from those storms.

The advisory serves as a warning for potentially dangerous heat conditions that require extra attention to staying cool and hydrated.
The threat for severe thunderstorms is expected to increase across the Mid-Atlantic on Friday as a cold front approaches from the west, bringing a more favorable environment for organized storm development.
After a more isolated storm threat on Thursday, Friday’s setup appears capable of producing more widespread thunderstorms during the afternoon and evening hours. A hot and humid air mass will remain firmly in place ahead of the advancing front, creating moderate to strong instability across the region. As daytime heating peaks, thunderstorms are expected to develop across portions of Pennsylvania and New York before expanding south and east into the Mid-Atlantic.
Forecast guidance suggests that storms may initially form as individual cells before merging into clusters or short line segments through the late afternoon and evening. As these storms organize, the primary hazard will become damaging straight-line winds, with some storms capable of producing localized wind damage and downed trees. An isolated instance of marginally severe hail cannot be ruled out with the strongest storms.
The Storm Prediction Center currently highlights the entire region in a Slight Risk (Level 2 of 5) for severe thunderstorms, reflecting the increasing confidence that at least scattered severe storms will develop. While the strongest upper-level winds are expected to remain west of the region, there should still be enough wind shear to support organized multicells and bowing segments capable of producing pockets of damaging winds.
Another factor that could enhance Friday’s severe weather potential is the possibility of a convectively induced disturbance moving into the region from the Great Lakes or Upper Ohio Valley. While the exact evolution remains uncertain, it could provide an additional source of lift and lead to greater storm coverage than currently anticipated.
For residents across Delmarva and the surrounding Mid-Atlantic, the greatest concern will be from late afternoon into the evening hours. While not everyone will experience severe weather, those that do could encounter damaging wind gusts, frequent lightning, torrential rainfall, and isolated hail.
Stay weather aware throughout Friday and have multiple ways to receive warnings, especially if you have outdoor plans. Forecast details will continue to be refined as newer data become available, but Friday currently appears to present the more significant severe weather threat compared to Thursday.
Federal weather officials confirmed Thursday that El Nino weather patterns have formed and are anticipated to grow stronger through the winter of 2026-27, according to the U.S. Climate Prediction Center.
The government weather agency noted that these El Nino conditions have emerged during the past month.
El Nino represents a natural climate event that happens when trade winds weaken, allowing warmer ocean temperatures to accumulate across the central and eastern equatorial Pacific. This weather pattern generally results in elevated global temperatures and shifts in weather systems, creating drought conditions in certain areas while producing excessive rainfall in others.
“El Nino is likely to have a negative impact on crop yields in Southeast Asia and India, where El Nino is typically associated with below-normal rainfall,” said Kyle Tapley, enterprise sales executive at Vaisala Xweather’s WeatherDesk.
India’s monsoon season provides approximately 70% of the nation’s annual precipitation and remains crucial for its farming industry, which represents roughly 18% of the country’s nearly $4 trillion economy. Reduced rainfall amounts could result in diminished harvests for crops including rice, cotton and soybeans, while also affecting winter crop production.
In Indonesia, rice producers are working to plant earlier than usual as they prepare for potential extended dry conditions this year. Malaysia’s economic minister has cautioned that El Nino may reduce crop production by 8% to 10% on average during this period.
“El Nino typically leads to a less-active U.S. hurricane season and we expect a below-normal Atlantic hurricane season this year. However, it is important to remember that a strong hurricane is still possible even in a less-active hurricane season,” Tapley said.
The current U.S. hurricane season started June 1 and continues until November 30.
The latest U.S. Drought Monitor paints an increasingly concerning picture across the Mid-Atlantic, with portions of the Delmarva Peninsula now classified under Extreme Drought (D3) conditions as prolonged rainfall deficits continue to take a toll on the region.
The expansion of Extreme Drought marks another significant step in a worsening pattern that has developed over recent months. Much of the Mid-Atlantic continues to experience varying levels of drought intensity, with widespread Moderate to Severe Drought surrounding the hardest-hit areas and abnormally dry conditions extending well beyond them. The U.S. Drought Monitor is updated every Thursday using a combination of precipitation data, soil moisture observations, streamflow measurements, groundwater information, and reports from local experts. Recent updates show the continued deterioration of conditions across parts of Delmarva and the surrounding region.
For residents across Delaware and Maryland’s Eastern Shore, the impacts are becoming increasingly visible. Dry soils, stressed vegetation, declining streamflows, and growing concerns for agriculture are all consequences of the prolonged lack of meaningful rainfall. The ongoing dryness also raises the risk of brush and woodland fires, especially during periods of low humidity and gusty winds.
Water managers and agricultural interests will be closely monitoring conditions through the summer, particularly if the region experiences additional stretches of hot weather with limited precipitation. While scattered thunderstorms can provide localized relief, they often fail to deliver the widespread soaking rainfall needed to significantly improve long-term drought conditions.
The drought also comes after an exceptionally dry spring across parts of the Mid-Atlantic. Climate data indicate that Delaware experienced one of its driest meteorological springs on record, helping to intensify moisture deficits that have persisted into early summer.
Looking ahead, meaningful and widespread rainfall will be needed over an extended period to reverse the growing deficits. Until then, residents should remain mindful of local burn restrictions, practice water conservation when possible, and stay informed as drought conditions continue to evolve across the region.
Federal weather officials confirmed today that El Niño has officially developed in the tropical Pacific Ocean, with forecasters issuing an El Niño Advisory as the climate phenomenon is anticipated to grow stronger through the fall season.
The National Weather Service announced that El Niño, which represents the warm phase of the El Niño Southern Oscillation climate pattern, is projected to reach moderate or strong intensity this autumn. Weather experts predict a 63% probability that sea surface temperatures will rise more than 2.0°C above normal in the Pacific monitoring zone. Should temperatures cross this threshold, NOAA would classify the event as a “very strong” El Niño.
El Niño occurs when equatorial Pacific Ocean temperatures climb 0.5°C above typical levels for multiple consecutive months. Weather scientists also track atmospheric conditions over this Pacific region, monitoring for changes in the Walker Circulation – a large-scale east-to-west airflow pattern created by temperature and pressure variations between the warm western Pacific and cooler eastern waters. El Niño is declared when this circulation pattern weakens and warmer waters move eastward toward South America.
The climate pattern typically reaches peak strength during winter months, with its most significant global effects occurring during northern hemisphere winter seasons. During typical El Niño winters, the jet stream over the northern Pacific tends to move southward, directing storm systems across the southern portion of the United States. This southward shift also creates drier conditions over the Northern Rockies and Ohio and Tennessee river valleys. Temperature-wise, El Niño frequently produces warmer than normal winter conditions across northern U.S. regions.
“Every El Niño is not the same; each one is unique with its own imprint on our weather,” stated Ken Graham, director of NOAA’s National Weather Service. “Advanced monitoring and an improved understanding of El Niño patterns allow the NWS to better predict and better prepare the public and our core partners for what is to come.”
Common El Niño impacts include stronger upper-level winds that typically reduce storm and hurricane formation in the Atlantic Basin, while weaker winds encourage tropical development in the eastern and central Pacific regions. The phenomenon also brings stormier conditions to the Southern U.S., increasing chances for both rain and snow during El Niño winters.
High tide flooding risks may increase in parts of the United States, particularly along the West Coast. The climate pattern also affects marine life migration patterns, with warm water species moving northward while cold water species relocate farther north or into deeper waters. These behavioral shifts impact fish growth, survival, and reproduction rates. Previous El Niño episodes have also contributed to increased harmful algal bloom formation along the U.S. West Coast.
In February, NOAA officially began using the Relative Oceanic Niño Index for monitoring sea surface temperatures and predicting El Niño and La Niña events. Unlike the traditional Oceanic Niño Index, which uses a fixed 30-year temperature baseline, the new index updates monthly, providing more reliable identification of climate events.
NOAA’s climate monitoring team has tracked both the traditional and new indices since 2021. After observing several years of climate phases and corresponding atmospheric responses, scientists determined that the new index better correlates with expected Walker Circulation changes, offering more valuable information to weather experts, emergency managers, and the public.
Severe thunderstorms ripped across the Midwest on Wednesday, leaving hundreds of thousands in the dark and creating travel chaos at Chicago’s major airports with over 1,000 flight disruptions.
Weather officials issued tornado warnings throughout Illinois, Kansas, northern Missouri and southern Iowa on Wednesday, with severe thunderstorm watches covering portions of the Great Lakes region.
The storm system reached the Chicago metropolitan area Wednesday afternoon, toppling trees and causing structural damage to buildings throughout the region.
Both Chicago O’Hare International Airport and Chicago Midway International Airport issued temporary flight holds Wednesday evening as thunderstorms moved through the area. John F. Kennedy International Airport in New York implemented similar ground stops due to severe weather conditions.
Flight tracking service FlightAware reported that by Wednesday night, more than 1,000 departing and arriving Chicago flights had been either delayed or cancelled.
Powerful winds tore portions of roofing from an apartment complex in the Chicago region, displacing residents, NBC 5 Chicago reported. Additional damage included collapsed barns in Wisconsin, destroyed structures in rural northern Missouri, and numerous fallen trees and power lines throughout the Midwest, as documented in online photos and videos.
Illinois experienced the most significant power disruptions with over 264,000 customers losing electricity, primarily concentrated in Cook County, while Michigan saw nearly 140,000 outages, according to poweroutage.com. Additional blackouts affected Kansas, Wisconsin, Iowa, Indiana and Ohio.
Commonwealth Edison Company, the electric utility serving northern Illinois, reported that the storms had brought down electrical poles and transmission lines.
“We know this is challenging and will restore service as safely and quickly as conditions allow,” the company said in a post on X.
NOAA has officially ushered in a new chapter in space weather forecasting with the start of operational service for its SOLAR-1 observatory, a next-generation mission designed to provide earlier and more accurate warnings of potentially disruptive solar storms. The milestone represents a significant advancement in the nation’s ability to monitor activity on the Sun and protect critical infrastructure both on Earth and in space.
Formerly known as Space Weather Follow On-Lagrange 1 (SWFO-L1), the spacecraft was renamed SOLAR-1 after reaching its permanent position near the Sun-Earth L1 Lagrange point, roughly one million miles from Earth. From this unique vantage point, the observatory continuously monitors the solar wind and tracks coronal mass ejections (CMEs) before they arrive at our planet.
The mission’s primary goal is to improve NOAA’s ability to issue timely space weather watches, warnings, and forecasts. Powerful solar storms can interfere with satellite operations, GPS navigation, radio communications, aviation, electric power grids, and even astronaut safety during missions beyond Earth’s protective atmosphere. Earlier detection means operators have more time to prepare and reduce potential impacts.
SOLAR-1 carries a suite of advanced instruments, including a compact coronagraph that images the Sun’s outer atmosphere and sensors that continuously measure the solar wind flowing toward Earth. The real-time data are transmitted directly to NOAA’s Space Weather Prediction Center, where they are incorporated into operational forecasts used by governments, utilities, airlines, emergency managers, satellite operators, and researchers around the world.
For skywatchers, improved space weather forecasting could also mean better predictions of auroral activity. During periods of heightened solar activity, strong geomagnetic storms can push the Northern Lights much farther south than usual, occasionally making them visible across portions of the Mid-Atlantic and Delmarva under favorable conditions. More accurate monitoring from SOLAR-1 should help forecasters better pinpoint the timing and intensity of these events.
As Solar Cycle 25 continues to produce frequent flares and coronal mass ejections, NOAA’s newest observatory is expected to play a critical role in safeguarding modern technology while advancing our understanding of the dynamic relationship between the Sun and Earth. With continuous observations from one of the most strategically important locations in space, SOLAR-1 marks a major leap forward in operational space weather monitoring.
The National Weather Service office in Mount Holly, New Jersey has issued a heat advisory that went into effect Monday at 2:36 PM EDT and will remain in place until Wednesday at 8:00 PM EDT.
The weather service issued the advisory on June 10th, warning of dangerous heat conditions that will persist through the middle of the week.
Residents are advised to take appropriate precautions during this period of elevated temperatures and heat-related risks.
The Mid-Atlantic is set for another round of dangerous summer heat as temperatures surge into the 90s on both Thursday and Friday, with heat index values climbing above 100 degrees in many communities. The combination of hot temperatures and high humidity has prompted Heat Advisories across much of the region, including portions of Delmarva.
A strengthening area of high pressure centered over the Southeast will continue to pump warm, humid air into the region through the end of the workweek. While an upper-level disturbance over Canada may slightly limit just how hot temperatures become, it will do little to reduce the risk of dangerous heat.
High temperatures on Thursday are expected to reach the low to mid 90s across much of the Mid-Atlantic, with many locations climbing even higher on Friday. When combined with dew points in the upper 60s to lower 70s, it will feel more like 95 to 104 degrees during the hottest part of the afternoon.
The highest heat index values are expected across southeastern Pennsylvania, central and southern New Jersey, and much of Delmarva, where prolonged outdoor exposure could quickly lead to heat-related illnesses.
Residents are encouraged to stay hydrated, limit strenuous outdoor activities during the afternoon hours, wear lightweight clothing, and check on vulnerable family members and neighbors. Never leave children or pets unattended in vehicles, where temperatures can become life-threatening in just minutes.
The heat won’t be the only concern. Scattered thunderstorms are expected to develop Thursday and Friday afternoon, with some storms capable of becoming severe and producing damaging winds. While these storms may offer temporary relief from the heat, they could also create hazardous conditions across the region.
Relief is expected to arrive behind a cold front late Friday. While temperatures will remain warm through the weekend with highs generally in the upper 80s to lower 90s, humidity levels are forecast to drop noticeably, making conditions significantly more comfortable and reducing the threat for additional heat advisories.
After a stretch of dangerous heat and humidity, attention is now turning to an increasing threat for severe thunderstorms across the Mid-Atlantic on both Thursday and Friday. We are monitoring multiple disturbances that could trigger strong to severe storms capable of producing damaging winds, large hail, and even an isolated tornado.
The overall weather pattern will remain favorable for thunderstorm development through the end of the workweek as hot, moisture-rich air remains firmly in place across the region. With temperatures climbing into the upper 80s and 90s and dewpoints well into the 60s and lower 70s, the atmosphere will become increasingly unstable each afternoon.
Thursday: Damaging Winds the Primary Concern
Thursday’s storms are expected to be driven largely by daytime heating, but an approaching disturbance moving out of the Midwest should provide enough additional lift to enhance thunderstorm development during the afternoon and evening hours.
The Storm Prediction Center has placed the entire Mid-Atlantic in a Slight Risk (Level 2 of 5) for severe weather. While wind shear is expected to remain relatively modest, the combination of hot temperatures and abundant moisture should create an environment favorable for strong thunderstorms.
The primary hazard will be damaging straight-line winds, although some storms could also produce large hail and a brief tornado if they become more organized.
Friday: Cold Front May Bring a More Widespread Severe Threat
The severe weather threat continues into Friday as an upper-level trough and an approaching cold front move closer to the region. These larger-scale weather features are expected to provide stronger forcing for thunderstorm development compared to Thursday.
Another Slight Risk has been issued across the region, with scattered to numerous thunderstorms expected to develop during the afternoon and evening hours.
As storms organize into clusters or bowing segments, the potential exists for a more concentrated area of damaging wind gusts pushing eastward toward the Mid-Atlantic coastline. Some storms may also produce marginally severe hail, while isolated rotating storms cannot be completely ruled out.
Main Hazards
Damaging wind gusts of 50 to 70+ mph
Large hail
Frequent cloud-to-ground lightning
Torrential rainfall and localized flooding
An isolated brief tornado cannot be ruled out
Stay Weather Aware
While there is still uncertainty regarding the exact timing and placement of the strongest storms on both days, confidence is increasing that at least scattered severe thunderstorms will develop somewhere across the Mid-Atlantic Thursday and Friday.
Residents across Delmarva and the surrounding region should keep a close eye on the latest forecasts and be prepared to receive watches and warnings, especially during the afternoon and evening hours when storm intensity is expected to peak.
The good news is that once the cold front moves through, the weekend forecast has trended drier with a gradual decrease in humidity and a return to more comfortable conditions.
Residents across Delmarva should prepare for the hottest weather of the year so far as a stretch of dangerous heat and humidity is expected to develop during the latter half of the week.
We are closely monitoring a strengthening ridge of high pressure that will build across the Mid-Atlantic beginning Wednesday and continuing into Friday. While recent forecast guidance suggests the ridge may not be quite as strong as earlier projections due to an upper-level disturbance tracking across Canada, temperatures are still expected to soar well above normal levels.
The combination of intense sunshine, warm air aloft, and moisture streaming northward from the Southeast will push afternoon temperatures into the low to mid-90s across much of Delmarva on Thursday and Friday. When combined with dew points in the lower 70s, it will feel significantly hotter.
Heat index values, which measure how hot it feels when humidity is factored in, are forecast to climb into the upper 90s and could exceed 100 degrees in some locations. The highest heat indices are expected across inland sections of Delaware, Maryland’s Eastern Shore, and portions of southern New Jersey.
While temperatures in the 90s are not uncommon during summer, the added humidity can place significant stress on the human body, especially for those working outdoors, participating in strenuous activities, or lacking access to air conditioning. Young children, older adults, and individuals with chronic health conditions are particularly vulnerable to heat-related illnesses.
Forecasts indicate that Heat Advisories may eventually be issued as confidence continues to increase in the magnitude of the heat. Residents are encouraged to stay hydrated, limit outdoor activities during the hottest part of the day, and check on neighbors who may be vulnerable to the extreme conditions.
The heat wave is not expected to last indefinitely. A cold front is forecast to approach and move through the region late Friday into Saturday. This front should bring a modest drop in temperatures and humidity levels for the weekend. While conditions will remain seasonably warm, the oppressive heat and tropical humidity currently expected late this week should ease heading into early next week.
Until then, Delmarva residents should prepare for several days of dangerous summer heat and take appropriate precautions to stay safe.
Powerful winds and dangerous seas hammered Wellington, New Zealand on Tuesday, shutting down air and water transportation while officials ordered hundreds of people living near the southern coastline to leave their homes.
Strong gusts at Wellington’s airport temporarily flipped a small aircraft onto its wing and wheel after the plane had completed its landing, according to an airport spokesperson who provided details via email.
“Nobody was injured and it was quickly righted,” the spokesperson stated.
The New Zealand Herald reported that passengers had already gotten off the aircraft when the wind caused it to tip over.
Wellington’s airport saw approximately eight flight cancellations. Air New Zealand notified travelers that predicted strong winds might affect departures from Wellington and provided alternative booking arrangements, according to Radio New Zealand’s coverage.
Officials declared an emergency situation for certain areas of Wellington after meteorologists issued warnings about waves reaching heights of 9 metres (29.5 ft) along the southern shoreline.
“We are now entering the forecast period for most significant swell impacts. If you are in the evacuation zone and have not left your property, please shelter in place,” Wellington City Council announced through a Facebook message.
Passenger boat operations connecting New Zealand’s North and South Islands were suspended Tuesday.
Weather officials predicted waves would increase quickly during Tuesday morning and early afternoon hours along eastern coastlines of both major islands and at the Chatham Islands.
Jonathan Delich, an Island Bay resident who runs Cook Strait Fishing Charters, informed the New Zealand Herald that he had canceled all Tuesday and Wednesday bookings.
“We wouldn’t take you fishing even if you wanted to … no one in their right mind would go out on the water today,” Delich commented.
MIAMI (AP) — Weather officials announced Monday that Tropical Storm Cristina has developed in Pacific waters near Nicaragua.
According to the National Hurricane Center in Miami, the storm is packing maximum sustained winds of 45 mph (75 kph). The system’s center was positioned 100 miles (160 kilometers) west-southwest of Managua, Nicaragua, and approximately 170 miles (275 kilometers) southeast of San Salvador, El Salvador.
Weather officials have issued a tropical storm warning spanning from Puerto Sandino to the Guatemala/El Salvador border.
The storm system is expected to produce rainfall amounts between 4 and 8 inches across coastal areas of Nicaragua, Honduras, El Salvador and Guatemala through Thursday, with some locations potentially receiving up to 12 inches (30 centimeters) of precipitation.
This marks the second tropical storm currently active in the Eastern Pacific Ocean. Tropical Storm Boris was also churning off Mexico’s coast Monday and was projected to reach landfall there on Tuesday.
A significant surge of summer heat is expected to develop across the Delmarva Peninsula during the second half of the week, with forecasters increasingly concerned about potentially dangerous heat and humidity levels by Thursday and Friday.
After a relatively warm start to the week, a warm front is forecast to move north through the region on Wednesday. This will open the door for a much hotter and more humid air mass to overspread the Mid-Atlantic, setting the stage for the hottest weather of the season so far.
Current forecast guidance indicates Thursday will likely be the peak of the heat wave. Strong southerly winds behind the warm front will transport very warm air into the region, allowing temperatures to climb well into the 90s across much of Delmarva. When combined with increasing humidity, heat index values could reach or exceed 100 degrees during the afternoon hours.
While there remains some uncertainty regarding Friday’s temperatures, confidence is high that the region will remain uncomfortably hot. Some forecast models suggest an upper-level ridge could strengthen over the East Coast, resulting in temperatures even warmer than Thursday. Other solutions indicate a weak disturbance could bring additional clouds and slightly lower temperatures. Regardless of the exact scenario, widespread highs in the 90s are expected.
The humidity will play a major role in determining the overall impacts of this heat event. Persistent southerly flow will continue to transport moisture northward from the Gulf and Atlantic, keeping dew points elevated. This combination of heat and humidity will increase the risk of heat-related illnesses, especially for those spending extended periods outdoors.
Residents are encouraged to stay hydrated, limit strenuous outdoor activities during the hottest part of the day, and check on vulnerable individuals, including the elderly, young children, and pets.
Relief from the heat appears possible over the upcoming weekend as a pair of cold fronts approach the region. The timing of these fronts remains uncertain, but they should eventually bring cooler temperatures and a reduction in the threat for extreme heat.
For now, Delmarva residents should prepare for several days of summer-like conditions, with Thursday currently appearing to be the most dangerous day of the upcoming heat wave.
Weather officials have issued a severe thunderstorm watch for the region, alerting residents to potentially dangerous weather conditions developing this evening.
The National Weather Service office in Mount Holly, New Jersey, activated the watch at 7:44 PM on June 6th, with the alert remaining in effect until 10:00 PM the same day.
A severe thunderstorm watch indicates that atmospheric conditions are favorable for the development of severe weather, including the possibility of damaging winds, large hail, and heavy rainfall.
Residents are advised to stay informed about changing weather conditions and be prepared to take shelter if warnings are upgraded or severe weather develops in their area.
Weather officials issued an alert for dangerous thunderstorm conditions Thursday evening, warning residents to take precautions during the storm system.

A stretch of summer-like weather across the Delmarva Peninsula will come to an end this weekend as a cold front sweeps through the region Saturday night, bringing the potential for scattered showers and thunderstorms, including a few strong storms.
Saturday is expected to remain largely dry with warm temperatures and increasing humidity. However, attention turns to the west Saturday evening as thunderstorms develop ahead of an approaching cold front. Those storms are expected to move eastward into portions of the Mid-Atlantic during the overnight hours.
The latest outlook from the National Weather Service’s Storm Prediction Center places areas north and west of the Interstate 95 corridor under a Marginal Risk for severe weather, with a Slight Risk extending into portions of northern New Jersey and the southern Poconos. While the greatest severe threat is expected to remain northwest of Delmarva, a few stronger storms could survive long enough to reach parts of eastern Pennsylvania, New Jersey, and northern sections of the region.
Damaging wind gusts and hail are the primary threats with any stronger thunderstorms. The overnight timing is expected to limit the overall severe weather risk as storms will likely weaken after sunset and continue to diminish as they move eastward.
Rainfall amounts also appear somewhat disappointing for a region desperately in need of moisture. Forecast rainfall totals generally range from one-tenth to one-quarter inch north and west of I-95, with locally higher amounts possible under heavier thunderstorms. Some communities may receive little or no rainfall at all.
The lack of widespread rainfall continues to be a concern as portions of Delaware, Maryland, New Jersey, and Pennsylvania remain under drought watches or drought warnings. Unfortunately, this frontal passage may represent the only meaningful opportunity for measurable precipitation over the next week.
Any lingering showers along the Delaware and New Jersey beaches Sunday morning should gradually move offshore as a secondary cold front pushes through the region. Drier and less humid conditions are expected to return later Sunday, providing a pleasant finish to the weekend.
Residents are encouraged to monitor forecasts through Saturday, especially if they have outdoor plans during the evening and overnight hours. While widespread severe weather is not expected across Delmarva, a few thunderstorms could still produce gusty winds, brief heavy rain, and frequent lightning.
