In Florida, Ivan struck at a time when the state is still reeling from Hurricanes Charley and Frances. Charley ravaged the state's west coast five weeks ago, while Frances pounded the east over Labor Day weekend.

Insurance experts put Ivan's damage at anywhere from $3 billion to $10 billion. Hurricanes Charley and Frances had combined estimated insured damages between about $11 billion and $13 billion.

Florida Gov. Jeb Bush deployed about 2,000 National Guard troops to the Panhandle. His brother, President Bush, was expected to visit the area Sunday — the president's third trip to review hurricane damage in Florida.

"I would think that when they do the final assessment, this is like Charley but a bigger area," the governor said.

The one-two-three punch also has bruised Florida's tourism industry. Following the storms, travel bookings to the state have dropped on a scale similar to the period following the Sept. 11 attacks, according to Dale Brill, senior vice president of marketing for Visit Florida, the state's official tourism marketing corporation.

In Milton, Fla., George Campbell got his first view Friday of what life will be like for a couple of weeks — sitting in traffic on Highway 90 that backed up for miles with people desperate for ice and water.

"My main concern? Just get our way of life back to normal," said Campbell, who retired from the Air Force in this region, dotted by Air Force and Navy bases and home to thousands of military retirees.

Naval Air Station Pensacola suffered massive damage during the storm, estimated in the hundreds of millions of dollars, the Navy said Friday. Ninety percent of the buildings on the base suffered "significant" damage, although no one was reported injured, according to a Navy statement.

Some military aircraft stationed in the Pensacola area had been flown out ahead of the storm, but other aircraft left behind may have been damaged.

Ivan weakened after coming ashore with 130 mph winds early Thursday, but it continued to spin off tornadoes and cause flooding across the South, already soggy after Charley and Frances. More than a million people were without power across eight states.

Among those flooded out of their homes was a 1,000-pound alligator that disappeared from a small coastal zoo in Alabama. The 14-foot gator, named Chucky, was one of nine alligators believed to have gotten out of the Alabama Gulf Coast Zoo during flooding, said zoo general manager Kate Ramon.

"We keep Chucky well fed, so he's normally not dangerous. But he's out now and he's dangerous. We've got to find him," she said.

Florida was praying that Ivan would be the last of the hurricane season's devastation. Out in the Atlantic, Tropical Storm Jeanne churned on a track toward landfall next week in the southeastern United States — and, possibly, Florida.

Even farther out, Tropical Storm Karl strengthened Friday in the far eastern Atlantic, but posed no immediate threat to land.
