Hurricane Ian's most damaging winds begin to hit Florida coast. Here are the latest updates

ST. PETERSBURG, Fla., (AP) — Hurricane Ian's most damaging winds began hitting Florida's southwest coast Wednesday, lashing the state with heavy rain and pushing a devastating storm surge after strengthening to the threshold of the most dangerous Category 5 status.

Fueled by warm waters in the Gulf of Mexico, Ian grew to a catastrophic Category 4 hurricane overnight with top winds of 155 mph (250 kph), according to the National Hurricane Center. The storm trudged on a track to make landfall north of the heavily populated Fort Myers area, which forecasters said could be inundated by a storm surge of up to 18 feet (5.5 meters).

“This is going to be a nasty nasty day, two days,” Florida Gov. Ron DeSantis said early Wednesday, stressing that people in Ian’s path along the coast should rush to the safest possible shelter and stay there.

Ian’s plodding pace meant the storm was expected to spend a day or more crawling across the Florida peninsula, dumping flooding rains of 12 to 18 inches (30 to 45 centimeters) across a broad area including Tampa, Orlando and Jacksonville in the state’s northeast corner.

Catastrophic storm surges could push 12 to (3.6 meters) of water or more across more than 250 miles (400 kilometers) of coastline, from Bonita Beach to Englewood, the hurricane center warned.

“It’s going to get a lot worse very quickly. So please hunker down," DeSantis said.
