US NHC says Isaias has become a hurricane

Hurricane Isaias emerged as the first storm of the 2026 Atlantic hurricane season and posed a threat to the Gulf Coast, including Mississippi, Alabama, and the western Florida panhandle. Florida Governor Ron DeSantis and Alabama Governor Kay Ivey each declared states of emergency for their respective counties, mobilizing resources to mitigate potential damage.

A hurricane warning was issued for the northern Gulf Coast from Ocean Springs, Mississippi, to Florida's Bay/Gulf County line. Isaias was located approximately 460 miles southwest of the Mississippi River's mouth, boasting sustained winds of 75 mph.

The storm was expected to move north of Mexico's Yucatan Peninsula on Thursday before heading towards the Gulf Coast on Friday. The National Hurricane Center projected landfall along the northern Gulf Coast of the U.S. late Friday or early Saturday, with potential impacts on Florida, Alabama, and Georgia. This would bring moderate to substantial rainfall to coastal areas and inland parts of the southeastern U.S. over the weekend and into next week.

Alongside the hurricane warning, a tropical storm warning was issued for a portion of the Louisiana coast and parts of Florida, while a storm surge warning extended from the Mississippi River's mouth to Yankeetown, Florida. Forecasts predicted between 3 to 7 inches of rain and up to 10 inches in some areas on the central Gulf Coast, with rainfall ranging from 1 to 5 inches across much of the Southeast, including the Tennessee Valley and the Carolinas.

Isaias' development into a hurricane on Thursday marked the latest date in 111 years for the season's first hurricane, tying a record set on October 8, 1905.
