About 30,000 people heeded orders to leave the Keys as the storm closed in, but an untold number refused, in part because to many storm-hardened residents, staying behind in the face of danger is a point of pride.

John Huston, who stayed in his Key Largo home, watched his yard flood even before the arrival of high tide.

"Small boats floating down the street next to furniture and refrigerators. Very noisy," he said by text message. "Shingles are coming off."Irma made landfall just after 9 a.m. at Cudjoe Key, about 20 miles outside Key West. During the afternoon, it rounded Florida's southwestern corner and hugged the coast closely as it pushed toward Naples, Sanibel, Fort Myers and, beyond that, Sarasota, at 14 mph (23 kph).

Forecasters warned some spots could see a storm surge of up to 15 feet of water.

Gretchen Blee, who moved with her husband to Naples from Long Island, New York, after Superstorm Sandy in 2012 heavily damaged their beach home, took cover in a hotel room as Irma raged.

"I said let's go and live the good life in paradise," she said. "And here we are."Some 400 miles north of the Keys, people in the Tampa-St. Petersburg area started bracing for the onslaught. The Tampa Bay area, with a population of about 3 million, has not taken a direct hit from a major hurricane since 1921.

"I've been here with other storms, other hurricanes. But this one scares me," Sally Carlson said as she snapped photos of the waves crashing against boats in St. Petersburg. "Let's just say a prayer we hope we make it through."After leaving Florida, a weakened Irma is expected to push into Georgia, Alabama, Mississippi, Tennessee and beyond. A tropical storm warning was issued for the first time ever in Atlanta, some 200 miles from the sea.

President Donald Trump approved a disaster declaration for Florida, opening the way for federal aid.

"Once this system passes through, it's going to be a race to save lives and sustain lives," Federal Emergency Management Agency chief Brock Long said on "Fox News Sunday."Florida's governor activated all 7,000 members of the Florida National Guard, and 10,000 guardsmen from elsewhere were being deployed.

Irma at one time was the most powerful hurricane ever recorded in the open Atlantic, a Category 5 with a peak wind speed of 185 mph (300 kph), and its approach set off alarm in Florida.

For days, forecasters had warned that Irma was taking dead aim at the Miami area and the rest of the state's Atlantic coast.

But then Irma made a more pronounced westward shift that put a bull's-eye on the Tampa area — the result of what meteorologists said was an atmospheric tug-of-war between weather systems that nudged Irma and determined when it made its crucial right turn into Florida.
