    Damage assessment determined that an EF0 tornado with a maximum
    wind speed of 65 mph briefly touched down along Omar Rd in
    Frankford, DE and moved ESE over a heavily forested area towards
    Shockley Town Rd. Several brief video clips shared by broadcast
    media and social media showed various angles of a tornado in
    progress in the heavily forested area between Omar Rd and
    Shockley Town Rd. Several large branches were twisted and snapped
    along Omar Rd. Additional damage is possible in the heavily
    forested area, but the survey team was unable to access the area.
    
    Special thanks to local media and the Sussex County Emergency
    Management for their assistance in this storm survey.

  • Severe Weather On Tap For Monday Evening Across Delmarva

    Severe Weather On Tap For Monday Evening Across Delmarva

    Strong to severe thunderstorms remain on tap as we venture into the afternoon and evening hours today as a strong cold front advances from the west. A “Slight Risk” of severe weather from the Storm Prediction Center laid across all of the Mid-Atlantic today.

    Looking at satellite this morning over towards our west a nice blanket of sunshine moving into the region to help destabilize the atmosphere with surface heating as temperatures are expected to be well into the 70s as dew points surge into the 60s to have plenty of moisture in place. Well suited for thunderstorm develop later today.

    The first round of storms will begin to develop across the Maryland Western shore around the mid-afternoon hours (4-5PM) which will have the highest chances of larger hail or even an isolated tornado being discrete in nature. Later in the evening hours as the cold front arrives, a squall line likely to develop with the primary threat of damaging straight line winds. Although a quick spin up in the line is always a possibility but those probabilities remain on the low side of things.

    As mentioned before, the primary threat for the storms this afternoon will be indeed damaging straight line winds from the main squall line that moves through towards the evening hours from 7-10PM. Winds gusting as high as 70 mph are possible with the strongest portions of the line. Heavy rainfall from the squall line of 1-3″/hr could lead to some localized flooding in spots. During the mid afternoon hours when a few discrete cells form will have the best shot of large hail to 1″ or locally larger. Tornado threat remains low but not impossible for the first cells to develop in the afternoon hours and then again in the line itself.

  • Delaware Severe Weather Awareness Week: Day 2 “Tornado Safety”

    Delaware Severe Weather Awareness Week: Day 2 “Tornado Safety”

    Delaware Severe Weather Awareness Week is a reminder that Delaware has been hit with many major weather events within the past five years. This year marks five years since Tropical Storm Isaias spawned the longest tornado ever recorded in Delaware, which wreaked a path of destruction as it traveled from Dover in Kent County to Glasgow in New Castle County. In April of 2023, a tragic tornado fatality occurred in Sussex County. It was the first tornado-related death since two people were killed near a mobile home community near Hartly on July 21, 1983. Record rainfall from the remnants of Hurricane Ida in 2021 caused historic flooding in parts of downtown Wilmington,

    What is a Tornado?

    A tornado is a violently rotating column of air extending from the base of a thunderstorm down to the ground. Tornadoes are capable of completely destroying well-made structures, uprooting trees, and hurling objects through the air like deadly missiles. Tornadoes can occur at any time of day or night and at any time of the year. Although tornadoes are most common in the Central Plains and the southeastern United States, they have been reported in all 50 states.

    What Are The Differences Between A Tornado Watch & Tornado Warnings

    What is the difference between a Tornado Watch, a Tornado Warning and a Tornado Emergency?  The National Weather Service has three key alerts to watch out for.

    • Tornado Watch: Be Prepared!  Tornadoes are possible in and near the watch area. Review and discuss your emergency plans, take inventory of your supplies and check your safe room. Be ready to act quickly if a warning is issued or you suspect a tornado is approaching. Acting early helps to save lives! Watches are issued by the Storm Prediction Center for counties where tornadoes may occur. The watch area is typically large, covering numerous counties or even states.
    • Tornado Warning: Take Action! A tornado has been sighted or indicated by weather radar. There is imminent danger to life and property. Move to an interior room on the lowest floor of a sturdy building. Avoid windows. If in a mobile home, a vehicle, or outdoors, move to the closest substantial shelter and protect yourself from flying debris. Warnings are issued by your local forecast office. Warnings typically encompass a much smaller area (around the size of a city or small county) that may be impacted by a tornado identified by a forecaster on radar or by a trained spotter/law enforcement who is watching the storm.
    • Tornado Emergency: Seek Shelter Immediately! A tornado emergency is the National Weather Service’s highest alert level. It is issued when a violent tornado has touched down in the watch area. There is a severe threat to human life and property, with catastrophic damage confirmed. Immediately seek refuge in the safest location possible. Call friends and family who are within the watch area to ensure they are aware of the situation. If you see a tornado approaching, do not attempt to outrun it in a vehicle; shelter in place. Once safe, be sure to monitor your local forecast for the latest updates.

    How To Prepare For A Tornado

    • Be Weather-Ready: Check the forecast regularly to see if you’re at risk for tornadoes. Listen to local news or a NOAA Weather Radio to stay informed about tornado watches and warnings. Check the Weather-Ready Nation for tips.
    • Sign Up for Notifications: Know how your community sends warnings. Some communities have outdoor sirens. Others depend on media and smart phones to alert residents of severe storms capable of producing tornadoes.
    • Create a Communications Plan: Have a family plan that includes an emergency meeting place and related information. If you live in a mobile home or home without a basement, identify a nearby safe building you can get too quickly, such as a church or family member.
    • Pick a safe room in your home, such as a basement, storm cellar, or an interior room on the lowest floor with no windows. Check more ideas for your family plan at: https://www.ready.gov/make-a-plan
    • Practice Your Plan: Conduct a family severe thunderstorm drill regularly so everyone knows what to do if a tornado is approaching. Make sure all members of your family know to go there when tornado warnings are issued. Don’t forget pets if time allows.
    • Prepare Your Home: Consider having your safe room reinforced. You can find plans for reinforcing an interior room to provide better protection on the Federal Emergency Management Agency website.
    • Help Your Neighbor: Encourage your loved ones to prepare for the possibility of tornadoes. Take CPR training so you can help if someone is hurt.

    What To Do During A Tornado

    Find out what you can do when a tornado strikes. Acting quickly is key to staying safe and minimizing impacts.

    • Stay Weather-Ready: Continue to listen to local news or a NOAA Weather Radio to stay updated about tornado watches and warnings.
    • At Your House: If you are in a tornado warning, go to your basement, safe room, or an interior room away from windows. Don’t forget pets if time allows.
    • At Your Workplace or School: Follow your tornado drill and proceed to your tornado shelter location quickly and calmly. Stay away from windows and do not go to large open rooms such as cafeterias, gymnasiums, or auditoriums.
    • Outside: Seek shelter inside a sturdy building immediately if a tornado is approaching. Sheds and storage facilities are not safe. Neither is a mobile home or tent.  If you have time, get to a safe building.
    • In a vehicle: Being in a vehicle during a tornado is not safe. The best course of action is to drive to the closest shelter. If you are unable to make it to a safe shelter, either get down in your car and cover your head, or abandon your car and seek shelter in a low lying area such as a ditch or ravine.

    What To Do After A Tornado Strikes

    • Stay Informed: Continue to listen to local news or a NOAA Weather Radio to stay updated about tornado watches and warnings. Multiple rounds of thunderstorms capable of producing tornadoes are possible during severe weather outbreaks.
    • Contact Your Family and Loved Ones: Let your family and close friends know that you’re okay so they can help spread the word. Text messages or social media are more reliable forms of communication than phone calls.
    • Assess the Damage: After the threat for tornadoes has ended, check to see if your property has been damaged. When walking through storm damage, wear long pants, a long-sleeved shirt, and sturdy shoes. Contact local authorities if you see power lines down. Stay out of damaged buildings. Be aware of insurance scammers if your property has been damaged.
    • Help Your Neighbor: If you come across people that are injured and you are properly trained, provide first aid to victims if needed until emergency response teams arrive.
  • Dagsboro Tornado 9/11/23 – Meteorological Deep Dive

    Dagsboro Tornado 9/11/23 – Meteorological Deep Dive

    Updated: [10:15 AM] NWS Mount Holly meteorologists have confirmed that a tornado occurred yesterday afternoon in Sussex County, Delaware near Dagsboro. Complete details will be available later this afternoon. #dewx

    Damage looking to be observed as a weak EF-0 Tornado with winds of 80 mph on Adams Road in Dagsboro, DE

    Out of surprise to many of residents living east of Dagsboro Delaware yesterday when a quick touchdown of a tornado occurred between Bunting and Piney Neck Road. With the hardest hit area being Adams road. Severe weather wasn’t on the ballet for yesterday but these freak events do happen from time to time when it comes to the microscale details.

    Video From Kelly Phillips

    A lot of key features played a role when you dig into the microscale levels. Overall weather synoptic pattern did not support the formation of tornadoes overall but the two colliding outflow boundaries did the trick. Similar to what happened several years ago in Ocean City Maryland when a EF-0 rolled through the city. These two boundaries interacting help creates vertical wind shear which is crucial for tornadogensis. When the storm matured with the very saturated surface with high dew points and extremely low cloud bases (LCL’s) was enough the get the mesocyclone spinning and tighten up down near the surface before dissipating a few minutes later. This tornado was only on the ground for about 5 minutes or less with a damage width of only about 100 yards.

    Big thank you to everyone who sent us photos, videos and the Sussex County EOC for helping with the survey efforts.

    LATE TUESDAY AFTERNOON JULY 5, 2022, BETWEEN 5:55 AND 5:56 PM EDT.

    THIS SUPERCELL ORIGINALLY DEVELOPED ALONG THE HOWARD/MONTGOMERY
    COUNTY LINE AS A RESULT OF A REMNANT MESOSCALE CONVECTIVE VORTEX
    (MCV) MOVING THROUGH THE REGION WHICH HAD EARLIER MOVED THROUGH
    THE OHIO VALLEY EARLIER IN THE DAY. IT EVOLVED INTO A CLUSTER OF
    CELLS INITIALLY BEFORE SPLITTING OFF INTO AN INDIVIDUAL SUPERCELL
    THAT WOULD DEVELOP ROTATION AS IT MOVED OUT OF SOUTHEASTERN
    MONTGOMERY COUNTY INTO NORTHWESTERN PRINCE GEORGES COUNTY. THE
    CELL DROPPED A TORNADO EARLIER IN THE AFTERNOON NEAR BOWIE, AND
    WOULD THEN CYCLE TO PRODUCE THE SECOND TORNADO IN HARWOOD.

    A BROADCAST MEDIA PARTNER PROVIDED VIDEO AND EYEWITNESS EVIDENCE
    OF A BRIEF SPIN-UP TORNADO WHILE LOCATED AT THE INTERSECTION OF
    BIRDSVILLE RD AND SOLOMONS ISLAND RD. THIS INDIVIDUAL NOTED THAT

    Storm Threats For Saturday

    We are getting closer and closer to our typical Severe Weather Season here on the shore. And we get a bit of a taste for it on Saturday. Now here’s the setup we are looking at.

    First off we have a fairly strong area of low pressure moving across the Great Lakes region with a strengthening mid level Jetstream across the Mid-Atlantic States. That’s the first set of ingredients for the storm setup for tomorrow.

    Now storm formation will be isolated in nature based on the latest high resolution model guidance. One thing is for sure we got the warmer temperatures and bit of surface moistures with dew points getting into the 60’s. So it’s going to be a little bit muggy out there by the early afternoon hours.

    Now we will see ample instability and wind shear across the region before our cold front arrives during the evening hours. MLCAPE (a product used to measure instability) showing values in the moderate instability category which is very crucial for thunderstorm development. Not to mention with the decent amount of instabilty, mid level lapse rates are fairly steep as well. Anytime we get Lapse Rates in the mid levels over 7C/km, that increases our hail threat just a bit with the colder air higher into the atmosphere. This is why we have a bit of a higher threat for seeing quarter size hail in storms that may develop. Not to mention we have some decent bulk shear (wind shear in a storm environment). 50-60kts is more than plenty to get a mix of line segments or even a couple of isolated supercell thunderstorms.

    Now in production for a little while, we have been working very hard at developing to really narrow down tornado threats in a 0-10 scale (0-100%). We are testing the waters on this one since there is a little bit of a tornado threat going into tomorrow. our TEHI product showing a level 1-2 threat out of 10 for tornadoes here on the shore. meaning storms will have a 10-20% chance of producing a tornado. Low level environment showing sufficient turning in the lowest levels which is very important for tornadogenisis.

    One limiting factor for storms tomorrow is the time of year we are in. Our coastal water temperatures do play a role in our storm threats with them being in the upper 40’s. This can create some stable air near the surface and cause storms to climb upscale and scrapping any tornado threat all together.
