Isaias becomes season's first hurricane as watches become warnings on Gulf Coast
Hurricane Isaias strengthened to 75 mph overnight, becoming the first hurricane of the 2026 Atlantic season as the NHC upgraded watches to hurricane and storm-surge warnings ahead of a Friday landfall between Mississippi and the Florida Panhandle.
Overnight, Isaias became the first hurricane of the 2026 Atlantic season — less than 20 hours after it became a tropical storm — and the National Hurricane Center upgraded the northern Gulf Coast from watches to warnings.
Hurricane-hunter aircraft confirmed sustained winds of 75 mph, making Isaias a Category 1 hurricane and the season’s ninth named storm, with the NHC issuing a special advisory on Wednesday night. As of the 11:30 p.m. ET advisory, the storm was about 460 miles south-southwest of the mouth of the Mississippi River, USA Today reported.
Warnings now span the northern Gulf Coast: a storm-surge warning from the mouth of the Mississippi River to Steinhatchee, Florida; a hurricane warning from Ocean Springs, Mississippi, to the Bay/Gulf County Line, Florida; and tropical storm warnings to either side, including the Jefferson/Plaquemines parish line in Louisiana, according to The Weather Channel.
Forecasters expect Isaias to peak as a Category 2 with 110 mph winds by Friday, making landfall late Friday or early Saturday between the Mississippi coast and the western Florida Panhandle. The NHC warns of 5 to 7 feet of surge from Ocean Springs to Indian Pass and in Mobile Bay, 3 to 7 inches of rain (locally 10 inches), and damaging winds capable of outages lasting days.
Evacuation orders were issued for the west end of Dauphin Island, Alabama, and Zones A and B in Okaloosa County, Florida, Fox Weather reported, while Shell and Chevron are shutting Gulf production facilities and evacuating workers, USA Today reported.
