Emergency declaration across 25 counties signals imminent hurricane disruption.
Context
What happened: Florida Gov. Ron DeSantis declared an emergency for 25 counties ahead of Tropical Storm Isaias, which could strengthen into a hurricane in the coming days.
Key numbers: 25 counties; winds 40 mph; moving east-northeast at 8 mph; centered about 285 miles west of Progreso, Mexico, and about 580 miles southwest of the Mississippi
Why it matters: The NHC forecasts Isaias to rapidly strengthen and become a hurricane by Friday, with hurricane watches likely issued for the northern U.S. Gulf Coast. If it strengthens, Isaias would be the first hurricane of the 2026 Atlantic season.
