GULF BREEZE, Fla. (AP) — Hurricane Isaias crashed into the U.S. Gulf Coast on Friday as a dangerous Category 2 storm, lashing communities in Alabama and the Florida Panhandle with damaging winds, heavy rain, flooding and life-threatening storm surge.

The first hurricane of the Atlantic season made landfall near Destin, Florida, the Miami-based National Hurricane Center said. It had maximum sustained winds of 105 mph (169 kph). The storm weakened to just below major hurricane status before it came ashore.

“The storm is here. Buckle down at this point. Don’t be getting out on the roads," Florida Gov. Ron DeSantis said at a news conference, adding that flash flooding would be a hazard "throughout the region.”

Hurricane-force winds lashed the Gulf shoreline in the low-lying coastal area known for powdery white sand beaches that are dotted with vacation homes, waterfront bars and seafood shacks. Forecasters warned the conditions could also stir up tornadoes.

Roads in Destin were flooded, while in nearby Pensacola, police warned residents to stay off the streets because of debris across roadways. Some Florida Panhandle counties temporarily suspended emergency response Friday night due to dangerous conditions.

Parts of southern Alabama were also flooded, with officials in Mobile reporting downed trees and power lines.

More than 512,000 customers in Florida and Alabama were without power Friday evening, according to poweroutage.com.

Residents in Panama City, Florida, braved the rain while filling sandbags Friday to protect their houses.

“I mean, it’s just the nature of the beast. It’s Florida," said Corliss Stone, who works for the fire department.

Many will brave Isaias at home

One of the biggest concerns is a storm surge that could be as high as 6 to 9 feet (1.8 to 2.7 meters), according to the hurricane center. Places most at risk include Florida’s Pensacola Beach and the Gulf Islands National Seashore.

Anne Petzold, who lives with her husband in the Florida beach community of Gulf Breeze, said everyone in their neighborhood planned to ride out the storm. The couple installed hurricane shutters and picked up anything in their yard that could turn into a projectile.

“Everybody does what they can do, everybody asks if they need help — they ask for help, they offer help. All good,” she said. “It’s just another adventure.”

Dangerous conditions are expected throughout the western panhandle, southern Alabama and southern Mississippi, the National Hurricane Center said. Several counties announced mandatory evacuations while Mobile, Alabama, imposed a curfew beginning Friday evening until morning.

In a sign of how serious the warnings are, dozens of Waffle Houses in the Florida Panhandle were closed, according to the company's website. The beloved Southern breakfast chain is known for staying open through severe weather and often is a measuring stick of a storm’s severity.

Kelsei Frazier, a Florida native living in Pace who is no stranger to hurricanes, knows all about the Waffle House Index.

“We joke because if Waffle House is still open, then you know it’s not a bad hurricane, but all the Waffle Houses that I know of within at least a normal range from us are closed,” said Frazier. “Which is a pretty big deal.”

DeSantis warned residents to expect power outages, gasoline shortages and closures of bridges and highways.

The state's National Guard deployed about 5,000 soldiers and airmen to help with the response, and search and rescue teams were ready to respond, while some prisons evacuated inmates.

The whole region could get soaked

Isaias is expected to weaken and be downgraded to a tropical storm by Saturday afternoon, the center said.

Still, heavy rain is forecast as it moves inland, with 4 to 8 inches (10 to 20 centimeters) or even more expected through the weekend from southern Alabama to southwestern Georgia.

Isaias, which is the first hurricane to hit the eastern U.S. since Milton tore up the Gulf Coast of Florida in 2024, also is expected to bring heavy rain and potential flooding to much of the Southeast over the weekend, and then to parts of the Midwest and Northeast into Monday.

Isaias grounds flights but likely to miss oil hubs

The storm grounded most Friday flights at several Panhandle airports, including all flights into and out of Destin-Fort Walton Beach Airport. President Donald Trump, meanwhile, scrapped his plans to attend Saturday’s football game between the University of Georgia and the University of Alabama in Tuscaloosa. He said he didn’t want to disrupt the emergency response.

Isaias was expected to miss the oil industry’s biggest hubs along the Gulf Coast, but fuel prices could rise if power outages shut down refineries for processing crude, industry experts said.

On Dauphin Island, a barrier island off the Alabama coast, Mayor Jeff Collier said he didn't expect major damage, “but at the same time, these things are very fickle and a little jog here or there, or some last-minute increase in strength — we just have to be prepared for the worst.”

Meanwhile in the Pacific, Hurricane Simon became a Category 2 storm on Friday and was expected to strengthen further before making landfall in Mexico this weekend.

Tropical Storm Rachel was also expected to bring heavy winds and rain to northern Mexico and Southern California over the weekend.
