Hurricane Isaias is no longer a hurricane — but the danger is far from over. Now a post-tropical cyclone, its remnants are pushing inland through the Southeast with heavy rain, flash flooding and a tornado threat, leaving at least four people dead and more than 400,000 customers without power. Flood watches now stretch from Georgia through the Carolinas and into the Mid-Atlantic, where the soggy remnants are expected to arrive on Sunday.
The season's first and record-late hurricane came ashore Friday night near Destin, Florida, as a Category 2 with 105-mph winds. Within hours the National Hurricane Center declared it post-tropical, with winds falling to 35 mph, and issued its final advisory early Saturday, dropping all tropical watches and warnings. But the Weather Prediction Center warned the effects were far from over: heavy rain and flash flooding would keep spreading across the Southeast and Southern Appalachians before the remnants reach the Mid-Atlantic and Northeast on Sunday.
At least four people have been killed — two in Florida and two in Alabama. In Florida's Escambia County, one person died after being trapped beneath a tree that fell on a house, and a man was found dead inside a garage where a generator had been running in an enclosed space; four family members, ages 72, 24, five and four, were hospitalized with non-life-threatening injuries. In Alabama, two storm-related deaths were reported, including a person killed when a tree fell on a home in Birmingham. The toll marks a deadly escalation from Saturday morning, when two fatalities had been confirmed.
Nearly 900,000 customers across Florida, Alabama and Georgia initially lost power, and more than 400,000 were still without electricity Saturday evening as crews assessed damage and began restoration. Florida alone accounted for more than 450,000 outages, concentrated in five Panhandle counties; in Bay County, 31,436 customers — nearly a quarter of all accounts — remained dark Saturday afternoon, and tens of thousands of outages were reported across Georgia, including Fulton and DeKalb counties.
Damage surveys revealed an unusual pattern: some of the worst wind damage occurred west of the storm's center, not on the eastern side where a hurricane's strongest winds typically strike. Forecasters say Isaias was already transitioning into a non-tropical storm at landfall, possibly allowing a "sting jet" to develop. Fort Walton Beach saw two to three feet of flooding. The National Weather Service warned residents of downed trees, fallen power lines, rain-swollen streams and standing water, and Florida's governor said the state remained in a "hazardous situation," urging caution — including running generators only outdoors.
The storm's inland march is disrupting life well beyond the coast. Georgia is under a statewide emergency declaration, and metro Atlanta braced for two to four inches of rain, gusts of 30 to 50 mph, flash flooding and an elevated tornado threat. Atlanta Pride canceled its Saturday festival programming in Piedmont Park, while Marietta's Chalktoberfest was fully canceled — the first weather cancellation in its history — and the Mayor's 5K at Hartsfield-Jackson Airport was postponed. In western North Carolina, communities remain under a high wind advisory and flood watch through Sunday, with flash flooding expected in the mountains.
The soggy remnants are now heading for the East Coast. The Weather Prediction Center placed parts of the Washington, D.C., Maryland and Virginia region under a marginal risk for excessive rainfall, with gusts of 20 to 30 mph — up to 40 mph in the Alleghenies. Along the New York and New Jersey coast, winds could briefly reach 25 to 35 mph Sunday night, with minor coastal flooding possible at high tide Sunday and Monday. Fans heading to the Browns-Jets game in New Jersey or the Giants-Commanders game near Washington, both at 1 p.m. ET, could face rain. No tropical watches or warnings are in effect for the Northeast or Mid-Atlantic.
Recovery is underway on the Gulf Coast: the Destin-Fort Walton Beach Airport reopened Saturday afternoon, and Orange Beach, Alabama reported minimal damage. Flood watches remain in effect for parts of the Southeast and Mid-Atlantic, where saturated ground could create dangerous travel conditions into Monday — a reminder that even after its final advisory, a late-season storm can punish states far from the coast.
