Overview
- The storm made landfall Friday night in the Florida Panhandle as a Category 3 hurricane and has since weakened to post-tropical/tropical-storm strength while moving north toward Alabama and interior U.S. regions.
- Local authorities confirmed at least two deaths and power companies reported roughly 900,000 customers without electricity across Florida and Alabama.
- U.S. agency data show about 1.3–1.5 million barrels per day of Gulf oil production were suspended and more than half of regional gas output was halted, pausing many offshore platforms and disrupting refinery operations.
- States of emergency and coastal evacuations were ordered, airports and coastal operations suspended, and the NHC warns continued storm surge, heavy inland rain, flooding and tornado risks as the system tracks into the Tennessee and Ohio valleys.
- Isaias is the Atlantic season’s first hurricane after an unusually quiet period linked to El Niño, with unusually warm Gulf waters allowing a localized rapid intensification that experts tie to long-term warming trends.
