TAMPA, Fla. — Florida work crews hustled to remove lingering wreckage from one hurricane ahead of another Tuesday, while thousands of people fearing a once-in-century direct hit from Milton streamed out of the Tampa Bay area, which has a population of more than 3.3 million people, to seek safety inland.

Though slightly weakened, Milton was still a powerful Category 4 storm and was expected to plow ashore late Wednesday or early Thursday, then remain fairly strong as it crosses Florida. The system could bring towering storm surges and the power to turn debris from Hurricane Helene into dangerous projectiles.

“All this crap is going to be missiles,” said Nick Szabo, who was hauling away piles of waterlogged couches, mattresses and appliances in Clearwater Beach. “It’s like a spear coming at you.”

Gov. Ron DeSantis said the state has deployed more than 300 dump trucks that have removed 1,200 loads of debris and continue to work around the clock.

After dawn Tuesday, trash trucks trundled up a nearly deserted street in normally bustling Indian Rocks Beach to gather mounds of debris. Sheriff’s deputies used a loudspeaker to urge anyone left to escape as soon as possible.

In Clearwater, Szabo said his team hauled some 260 tons of debris Monday and planned to continue until Tuesday evening. “It feels good to help,” Szabo said.

The county that’s home to Tampa ordered areas adjacent to the bay and all mobile and manufactured homes to evacuate.

“You do not have to get on the interstate and go far away,” DeSantis told a news conference, assuring residents there would be enough gasoline to fuel their cars for the trip. “You can evacuate tens of miles. You do not have to evacuate hundreds of miles away. You do have options.”

Most of Florida’s west coast was under a hurricane or tropical storm warning as the system and its 155 mph winds spun just off Mexico’s Yucatan peninsula. Hurricane warnings were extended early Tuesday to parts of the state’s east coast.

In Riverview, south of Tampa, several drivers waiting in a long line for fuel Tuesday said they had no plans to evacuate.

“I think we’ll just hang, you know — tough it out,” said Martin Oakes, of nearby Apollo Beach. “We got shutters up. The house is all ready. So this is sort of the last piece of the puzzle.”

Ralph Douglas, who lives in neighboring Ruskin, said he, too, will stay put, in part because he worries about running out of gas trying to return after the storm or getting blocked by debris.

“Where I’m at right now, I don’t think I need to evacuate,” he said.

The National Hurricane Center downgraded Milton early Tuesday to a Category 4 hurricane, but forecasters said it still posed “an extremely serious threat to Florida.”

Forecasters warned that the sea could surge as high as 15 feet at Tampa Bay, leading to evacuation orders for beach communities all along the coast. In Florida, that means anyone who stays is on their own and first responders are not expected to risk their lives to rescue them at the height of the storm.

The state has helped evacuate over 200 health care facilities in Milton’s path, and more than 30 county-run shelters are open, DeSantis said.

At the Tampa airport, John Fedor and his wife were trying to catch a cab to a storm shelter after missing multiple flights home to Philadelphia. They had hoped taking a Caribbean cruise would bring them closer, but tensions were rising after they spent nearly $1,000 on unplanned transportation and hotel rooms due to travel delays.

After a two-mile walk to the airport, Fedor’s suitcase cracked open and the wheels broke.

“We looked into driving home, taking the train home, but nothing worked out,” John Fedor said. “We’re kind of like stranded here.”

Milton is forecast to cross central Florida and dump as much as 18 inches of rain while heading toward the Atlantic Ocean, according to the hurricane center. That path would largely spare other states ravaged by Helene, which killed at least 230 people on its path from Florida to the Appalachian Mountains.

Tampa Bay has not been hit directly by a major hurricane since 1921.

President Joe Biden approved an emergency declaration for Florida, and the White House announced Tuesday that he would postpone a trip to Germany and Angola to monitor Milton, “given the projected trajectory and strength” of the storm.

“This could be the worst storm to hit Florida in over a century,” Biden told reporters. “God willing it won’t be. But that’s what it’s looking like right now.”

Rep. Kathy Castor, D-Fla., said 7,000 federal workers were helping in one of history’s largest such mobilizations.

“I need people to listen to their local officials to get out of harm’s way,” said Deanne Criswell, administrator of the Federal Emergency Management Agency. “People don’t need to move far. They just need to move inland.”

Stragglers were a problem during Helene and also Ian in 2022.

Many residents said they evacuated during previous storms only to have major surges not materialize. But there was evidence Monday that people were heeding the warnings to get out before Milton arrives.

Vehicles streamed north on Interstate 75, and traffic clogged the southbound lanes for miles as other residents headed for relative safety on the other side of the state, though nearly all of Florida is expected to see some of Milton’s effects.
