Tropical Storm Isaias is strengthening in the Gulf of Mexico and is expected to become the first hurricane of the 2026 Atlantic season before reaching the U.S. Gulf Coast later this week.
According to the National Hurricane Center, Isaias had maximum sustained winds of 45 mph Wednesday morning and was located about 540 miles southwest of the mouth of the Mississippi River. The storm was moving east-northeast at approximately 8 mph.
Forecasters expect the storm to strengthen rapidly as it moves across the Gulf’s warm waters. Current projections indicate that Isaias could make landfall late Friday or early Saturday, with the potential landfall zone stretching from eastern Louisiana to the Florida Panhandle.
The National Hurricane Center has issued a Hurricane Watch for portions of the northern Gulf Coast, along with a Storm Surge Watch extending from the mouth of the Mississippi River to Yankeetown, Florida.
The storm could bring dangerous winds, storm surge and heavy rainfall to coastal areas. Forecasts call for widespread rainfall of 3 to 6 inches, with locally higher amounts of up to 10 inches possible along parts of the Gulf Coast.
The storm’s effects could extend well inland, with heavy rain and flooding possible across parts of the Southeast, including areas of the Tennessee Valley and Appalachians.
Isaias would become the first Atlantic hurricane of the year unusually late in the season. The Atlantic hurricane season officially runs from June 1 through November 30.
Residents along the northern Gulf Coast are being urged to closely monitor the forecast and prepare for potentially dangerous conditions as Isaias approaches.
