Hurricane Isaias has become the first Atlantic hurricane of 2026 and is tracking toward the northern Gulf Coast, where governors have already declared emergencies and ordered evacuations.
The storm strengthened into a hurricane Wednesday night after a long stretch of quiet weather, and by Thursday afternoon it was packing maximum sustained winds of 85 mph while centered about 355 miles south of the mouth of the Mississippi River, NPR reported.
Forecasters said Isaias was moving east-northeast at 10 mph and could approach the northern Gulf Coast on Friday afternoon, with landfall possible late Friday or early Saturday near Mobile Bay and the Florida-Alabama line.
That forecast put Alabama and Florida into rapid preparation mode. Alabama Gov. Kay Ivey declared a state of emergency for 40 counties. Florida Gov. Ron DeSantis declared a state of emergency for 25 counties and warned that the storm’s structure would not hit every shoreline the same way.
In a Thursday afternoon update, DeSantis said the storm’s shape matters as much as its wind speed.
"The issue with this storm is it's a very eastside-heavy storm,"
the Florida governor said, pointing residents and local officials toward the side of the system most likely to drive rain, surge, and outages.
He also said the ground is already wet.
"We are saturated"
DeSantis told the public, a plain warning that fresh rain on soaked soil raises flood risk even if the storm does not linger.
Florida had mandatory or voluntary evacuation orders in effect for parts of seven counties as of midday Thursday. The governor said the state was staging more than 6,000 utility linemen and restoration workers, with about 5,000 Florida National Guard personnel expected to be available.
The National Hurricane Center posted a hurricane warning for the Gulf Coast from Ocean Springs, Miss., to the area around Mexico Beach, Fla. Storm surge alerts covered a wider stretch of shoreline than the hurricane warning alone.
If the peak surge arrives with high tide, water levels of 5 to 7 feet are possible from Ocean Springs to Indian Pass, Fla. Rain totals of 3 to 7 inches are forecast from southeastern Louisiana to the Florida Panhandle over the weekend, with up to 10 inches in some spots.
Warm Gulf water helped the system gain strength. Sea surface temperatures around 87 degrees in part of the Gulf of Mexico gave the storm fuel to intensify as it moved north.
The Florida Panhandle sits in the zone most likely to take the hardest hit on power and rainfall if the track holds. Officials there are preparing for outages as crews and Guard units wait on standby.
Isaias did more than earn a name upgrade. It ended an unusually empty stretch of the Atlantic season.
The season began June 1. By the time Isaias reached hurricane strength, the basin had gone more than four months without an Atlantic hurricane. The National Hurricane Center has said that in an average year in recent decades, the Atlantic would already have produced at least five hurricanes by this point on the calendar.
Philip Klotzbach, a research scientist in the Department of Atmospheric Science at Colorado State University, told NPR the quiet stretch stood out even against a season expected to run below normal.
"While we anticipated a well below-average season this year, it's certainly been surprising to see just how quiet it has been,"
Klotzbach said. He noted that since 1851, only three hurricane seasons on record had produced no hurricanes through Oct. 7.
A strong El Niño pattern has been cited as a major reason Atlantic activity stayed muted for so long. That same pattern tends to suppress storms more over the open tropical Atlantic than over the Gulf, which left room for a system like Isaias to build once it found warm water closer to the U.S. coast.
Klotzbach also pointed to one feature that could limit the worst inland flooding if the forecast holds.
"Isaias will be moving quickly as it comes onshore, which should hopefully reduce the chances for catastrophic flooding,"
he said. A faster-moving storm still brings surge and wind. It just dumps less total rain over the same towns than a system that stalls.
As of Thursday afternoon, Isaias was not a classic round bull’s-eye on satellite. The circulation leaned like an italicized letter O, with more of its weight on the eastern side, the same trait DeSantis flagged for coastal counties.
Models remained divided on the exact timing of a turn toward the northeast over Thursday and Friday. The practical window for coastal residents stayed the same: approach on Friday afternoon, possible landfall late Friday or early Saturday near the Florida-Alabama border region.
No injuries, deaths, or damage totals had been reported at the time of the Thursday coverage. The story on the ground was still preparation, emergency orders, evacuation notices, staged repair crews, and surge warnings, not recovery.
For Gulf Coast communities already dealing with wet ground, the checklist is familiar and unforgiving: heed local evacuation orders, plan for power loss, and treat surge zones as the first danger line when a hurricane aims at Mobile Bay and the Florida Panhandle.
When a quiet season finally sends a hurricane at the coast, the governors who move early on emergency powers, Guard readiness, and utility crews are doing the job voters hired them to do.
