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.
