Tropical Storm Isaias has formed in the Gulf of Mexico and is expected to rapidly strengthen, potentially becoming the first hurricane of the 2026 Atlantic season.
As of the latest 11AM Wednesday update, Isaias had maximum sustained winds of 45 mph and was moving east-northeast at about 8 mph. The storm is expected to turn northward and speed up over the next few days, approaching the northern Gulf Coast by Friday afternoon.
Intensity Forecast
Isaias is getting better organized, with Hurricane Hunter data showing the storm’s center becoming better aligned. It is moving over very warm Gulf waters with plenty of moisture and relatively light wind shear, creating a favorable environment for rapid strengthening.
The National Hurricane Center expects Isaias to become a strong hurricane before approaching the northern Gulf Coast Friday.
Record Setting Storm
If Isaias becomes a hurricane this week, it would mark the first hurricane of the 2026 Atlantic season.
If Isaias reaches hurricane strength by October 8, it could tie the record for the latest first hurricane on record, set on October 8, 1905.
The 2026 season has already set the record for the latest first hurricane in the modern satellite era, which began in 1966.
Forecast Track
The biggest concern is along the northern Gulf Coast, with the Florida Panhandle among the areas that could see significant impacts.
The exact track is still uncertain, but Isaias is expected to approach the Gulf Coast Friday afternoon. A Storm Surge Watch is now in effect from the mouth of the Mississippi River to Yankeetown, Florida, while a Hurricane Watch is in effect from Bay St. Louis, Mississippi, to Indian Pass, Florida.
Isaias is also expected to grow in size as it approaches the coast, meaning impacts could extend well away from the center.
For Central Florida, Isaias is not expected to bring direct hurricane impacts, but the storm could pull additional tropical moisture into the Southeast and contribute to a wetter pattern across the region into the weekend. Heavy rain and flooding will be possible across portions of the Southeast.
