Fort Pierce, Fla. ? About three-quarters of a million residents of Florida’s east coast were urged to evacuate — again — as Hurricane Jeanne churned westward Friday and threatened the state with its fourth pounding in six weeks.

The 100-mph storm could come ashore somewhere on the state’s east coast by Sunday, targeting some of the same areas hit by previous storms and potentially turning piles of still-uncleared debris into deadly missiles.

“I’m not staying in this bunch of junk,” 76-year-old Ed Oglesby said as he patched his torn roof in a Hutchinson Island mobile home park still littered with twisted metal from homes wrecked by Hurricane Frances.

A single state hasn’t been hit by four hurricanes in one season since Texas in 1886. Jeanne could continue a devastating run that has thrashed Florida’s Panhandle (Ivan), southwest coast (Charley) and midsection (Frances). Together, they have caused billions of dollars of damage and at least 70 deaths in the state.

“I know people are frustrated, they’re tired of all this,” Gov. Jeb Bush said. “Trust me, their governor is as well.”

Crews with bulldozers worked Friday to clear the mess of flattened homes, torn roofs and snapped trees left when Frances tore through the heart of the state earlier this month. But many acknowledged it was a losing battle.

“With another hurricane, there’s just too much there — we just don’t have the manpower to get it all done,” said Martin County spokesman Greg Sowell, who estimated nearly 80 percent of debris remained from Frances.

Pam Custis shed tears Friday as she looked at a heap of smashed furniture and flooded carpets in front of her Fort Pierce condominium, which has been stripped to a skeleton of concrete floors and metal frames. The debris pile was as tall as she is.

“This is all we have left,” she said of her condo’s shell. “When this other hurricane comes, this pile is going to be knocking down the rest of it.”

Eight counties along about 300 miles of coastline issued evacuation orders for residents on barrier islands, low-lying areas and mobile homes.

But with almost the entire state in Jeanne’s danger zone and a hurricane warning stretching from Miami-Dade County in the south to St. Augustine in the north, some questioned whether there was any safe place to run.

“I ain’t going anywhere unless they make me,” retiree Larry Ruby said as he patched the roof of his Hutchinson Island mobile home. “I don’t think you can get away from it.”
