Hurricane Isaias Hits Category 2 — and It's Still Strengthening Ahead of Friday Landfall

PENSACOLA, Fla. — Hurricane Isaias isn't done climbing. The 11 p.m. ET Thursday advisory from the National Hurricane Center had the storm at 105 mph — officially a Category 2 — centered about 260 miles south of the mouth of the Mississippi River and picking up speed, its forward pace up to 14 mph with the pressure still dropping. And forecasters say the worst of the wind is still a few hours out: the center's forecast calls for a brief run to Category 3, 115-mph status on Friday, before wind shear slams the brakes and the storm makes landfall late Friday with about 100-mph winds near the Florida-Alabama border.

This is the late-night update on a storm we've been tracking all day — and if you only read one thing before bed, make it this: Friday is the day. "Isaias will be a dangerous hurricane with significant storm surge, damaging winds, and flooding rains when it reaches the northern Gulf Coast," the hurricane center said in its 11 p.m. discussion, warning that the wind field will keep growing and push gusty winds well inland across the Southeast.

The 11 p.m. picture: stronger, faster, and headed northeast

Over Thursday evening, Isaias kept feeding on the warm Gulf. The storm's center was about 260 miles south of the mouth of the Mississippi River at 11 p.m. ET, moving northeast at 14 mph, and the barometric pressure was still falling — the classic sign a storm is building steam. USA TODAY reported that the National Hurricane Center sees "rapid intensification" as a distinct possibility as the storm crosses the central Gulf, and AccuWeather's chief meteorologist said there's a real chance Isaias peaks as a major hurricane, Category 3, over the central Gulf on Friday.

The important nuance: the Category 3 peak is expected to be short-lived. As Isaias approaches the coast, increasing wind shear should tear into its peak winds. The official forecast has the storm at about 100 mph as it comes ashore late Friday or overnight — somewhere on a stretch of coast between Mobile, Alabama, and Destin, Florida. The Pensacola News Journal reported that the Wednesday-morning track and the model consensus put the most likely landfall between Mobile and Destin, centered on Pensacola. But as meteorologist Ryan Truchelut of WeatherTiger told the USA TODAY Network, the wind field is forecast to grow larger even as the peak winds come down — a big, lopsided storm with rainfall, wind, surge, and tornado impacts reaching hundreds of miles east of wherever the center crosses the shore.

For context on what's under warning right now: a hurricane warning is in effect from Ocean Springs, Mississippi, to the Bay/Gulf County line in Florida. A tropical storm warning covers the Florida coast from the Bay/Gulf County line to the Aucilla River. A storm-surge warning runs from the mouth of the Mississippi River to the Suwannee River. All told, USA TODAY reported, watches and warnings for storm surge, flooding, and high winds cover more than 600 miles of coastline — from southeastern Louisiana to the Florida coast south of Tallahassee.

Surge is the killer

The number everyone on the Gulf Coast needs to internalize is the surge. The National Hurricane Center's peak forecast calls for 5 to 7 feet of storm surge from Ocean Springs, Mississippi, to Indian Pass, Florida, and in Mobile Bay — with 4 to 6 feet from Indian Pass to the Steinhatchee River, and lower but still dangerous totals farther east. Florida Sen. Rick Scott put it as bluntly as it can be put during a news conference Thursday at the Port of Pensacola: "You cannot survive 5 to 7 feet of storm surge — it will kill you," Scott said, warning the region could also see up to 10 inches of rain and a big tornado risk.

Storm-surge specialist Brad Reinhart of the National Hurricane Center has been saying it all week. Reinhart was a high school student on the Mississippi coast when Katrina's record 28-foot surge wiped homes down to clean concrete slabs in Bay St. Louis, and he's spent his career trying to make people understand what water can do. Isaias's surge will be far smaller than Katrina's, but as Reinhart told USA TODAY earlier this year, the surge warnings "mean your life is in danger and you need to heed the warnings and evacuate if told to do so." Five to seven feet is over most people's heads, and it doesn't knock — it rushes in.

Rainfall is the other half of the water story. The hurricane center is forecasting 4 to 8 inches across southern Alabama, the Florida Panhandle and Big Bend, and southwest Georgia from Friday through the weekend, with localized totals up to 15 inches possible in banding across the Panhandle and Big Bend. Flash and urban flooding are likely across the region, the hurricane center said, with considerable impacts possible across much of southern Alabama and the Panhandle into southwestern Georgia. The National Weather Service in Mobile said residents from Pensacola through the western Panhandle should expect "significant impacts," including hurricane-force winds near the center, life-threatening surge, dangerous rip currents, numerous flash floods, and tornadoes — especially east of the center.

Evacuations, closures, and airports going quiet

Alabama Gov. Kay Ivey went on video Thursday urging residents and visitors to get ready — and then she went further. At the request of local officials, all tourists and visitors in Baldwin County south of the Gulf Intracoastal Waterway, plus everyone on Dauphin Island in Mobile County, must evacuate immediately, Ivey said: "that means visitors in Gulf Shores, Orange Beach and Dauphin Island need to head home." She also closed state offices and buildings in nine counties — Baldwin, Coffee, Covington, Dale, Escambia, Geneva, Henry, Houston, and Mobile — starting Friday at noon CT. A day earlier she'd declared a state of emergency for 40 Alabama counties. In Florida, Gov. Ron DeSantis declared a state of emergency in 25 North Florida counties, from Escambia to Baker.

The Pensacola News Journal reported a string of evening closures: Destin-Fort Walton Beach Airport closed to commercial operations at 9 p.m. CT tonight, Pensacola International Airport halts commercial flights at 10 a.m. CT Friday, and Leon County schools are dismissing early Friday. More than a dozen Florida school districts have already said they'll be shut Thursday, Friday, or both, and officials on both sides of the state line are canceling events and shuttering government offices ahead of the storm.

The record this storm just broke

Isaias is historic for something beyond the forecast cone: it's the latest first hurricane of any Atlantic season in the reliable record — and not by a little. The storm's development into a hurricane leaves the season's 1914 no-hurricane record technically intact, but AccuWeather reported that Isaias broke the 1905 record for the latest first hurricane of a season by about three and a half hours. USA TODAY noted the 2026 Atlantic season has been one of the slowest in recent memory, thanks to a powerful El Niño in the Pacific churning up the shearing winds that strangle Atlantic storms — plus Saharan dust, dry air, and a drought in Ethiopia that killed off the thunderstorm clusters that seed hurricanes. The Pacific, meanwhile, has had at least 21 named storms, and tropical storms Rachel and Simon were swirling off the West Coast as Isaias bore down on the Gulf.

One more piece of context worth having: the National Weather Service in Greenville-Spartanburg put out a graphic Thursday comparing Isaias to Hurricane Helene, the Category 4 that devastated the Southeast in 2024. The takeaway, as the weather service said Thursday: "the current forecast is far less severe." Helene dumped up to 30 inches of rain in some areas; Isaias's forecast for that region is 1 to 3 inches, with dry conditions ahead of the storm helping ease the flooding concern.

What Friday actually looks like: tornadoes east, flooding everywhere

The wind forecast goes beyond the cone in a way people underestimate. Much of Alabama and eastern Mississippi could see gusts of 50 to 60 mph Friday night into Saturday morning as Isaias moves in, which is enough for widespread power-line trouble — and gusts will extend well inland across Alabama, Mississippi, north Georgia, and the southern Appalachians during the day Saturday as the storm grows in size and accelerates. "The impacts from Isaias will be felt hundreds of miles away from where the center comes ashore," WPLG-TV hurricane specialist Michael Lowry wrote Thursday, "especially to the east of its track."

And then there are the tornadoes. The hurricane center says an isolated tornado risk begins Friday night in coastal areas of Alabama, the Florida Panhandle, and far southwestern Georgia, continuing into Saturday for eastern Alabama, Georgia, and the Panhandle. Truchelut, the WeatherTiger meteorologist, put the tornado risk more pointedly: expect embedded severe storms with high tornadic potential east of where landfall occurs. Flash-flood risk is rated at Level 3 of 4 for Mobile and the western Panhandle. The National Weather Service in Tallahassee told residents to finalize preparations by midday Friday — after that, the weather does the scheduling.

National Hurricane Center Director Michael Brennan said it plainly in a Thursday livestream: "Today is the day to prepare, and get ready, and be in your safe place by tomorrow." The storm hits late Friday. Tonight is the window — and the window is closing.
