Hurricane Isaias weakens to post-tropical cyclone after Florida landfall

Hurricane Isaias made landfall on Friday night along the northern Gulf Coast of Florida near Destin as a Category 2 storm, bringing maximum sustained winds of 105 mph (169 kph) before swiftly degrading. The storm represents the first hurricane of the 2026 Atlantic season, which formed with a delay due to El Niño conditions.

As the system pressed inland across the western Florida Panhandle and into southern Alabama, it was downgraded to a post-tropical cyclone. Forecasters warned that despite the downgrade, the storm continued to pose severe hazards, including flash flooding, urban and river flooding, and life-threatening storm surges across the Southeast.

Storm Impact and Power Outages Across the Southeast

The system battered coastal and inland communities alike, tearing roofs from structures, snapping utility poles, and uprooting trees. In Pensacola, local authorities warned residents to stay off debris-strewn roadways as howling winds tore roofs from homes and businesses and knocked out power. Power outage tracking firms reported hundreds of thousands of homes and businesses plunged into darkness, with figures reporting over 430,000 in Florida, nearly 300,000 in Alabama, and approximately 40,000 in Georgia according to PowerOutage.us reports.

Emergency Responses and Mandatory Evacuations

Governors across the region mobilized emergency services ahead of the impact. The governors of Mississippi, Alabama, and Florida declared states of emergency to fast-track federal assistance. Homeland Security Secretary Markwayne Mullin confirmed via X that emergency declarations had been approved for Florida and Alabama to ensure federal resources were available. Florida deployed approximately 5,000 National Guard soldiers and airmen for search-and-rescue and route-clearance duties, while wildlife officials readied airboats, shallow-draft vessels, and all-terrain vehicles.

Mandatory evacuation orders were issued for coastal communities and vulnerable non-residents. Senator Rick Scott urged residents in designated zones to evacuate immediately via social media, declaring, "DO NOT WAIT! Get out NOW!" Similarly, Alabama Governor Kay Ivey issued mandatory evacuations for non-residents, tourists, and visitors in key affected counties. In Houston County, Alabama, emergency management officials closed all roads indefinitely due to downed trees, snapped power lines, and active flash flood warnings.

President Donald Trump told reporters outside the White House that officials were watching the storm closely and that it was under control.

As Isaias continues its track across Alabama and into the Tennessee Valley over the weekend, emergency management agencies advise residents to remain sheltered indoors while post-tropical storm force winds and heavy rains persist well inland.
