Tropical Storm Isaias formed in the southwestern Gulf of Mexico early Wednesday and is forecast to intensify into a hurricane before striking the U.S. Gulf Coast. The National Hurricane Center (NHC) expects the system to become the first Atlantic hurricane of the 2026 season by Thursday morning. Forecasters project the storm will move north and make landfall in the Florida Panhandle as a Category 1 or 2 hurricane on Friday night.
If Isaias achieves hurricane status on Thursday, it would be the latest date on record for the first hurricane of an Atlantic season. The storm was located approximately 225 miles west-northwest of Progreso, Mexico, on Wednesday afternoon and was reported to be gaining strength over open water. The NHC stated it is increasingly likely that Isaias will be a significant hurricane when it reaches land.
State officials have issued emergency declarations in preparation for the storm's arrival. Florida Governor Ron DeSantis issued a state of emergency for 25 counties on Tuesday evening, and Alabama Governor Kay Ivey issued a similar order for 40 counties on Wednesday. Hurricane watches and storm surge watches are currently in effect for coastal areas of Mississippi, Alabama, and the western Florida Panhandle.
A person living in the projected path near Pensacola or Mobile would notice increased wind speeds and rain starting Friday morning, with the most severe conditions occurring late Friday night. These conditions may lead to power outages. Inland residents in Mississippi and Alabama are expected to see heavy rainfall on Saturday as the system weakens.
The arrival of the season's first hurricane in October would set a record for the latest such occurrence. Local governments will continue to monitor updates from the National Hurricane Center as the storm's path and intensity evolve leading up to the projected Friday night landfall.
