KEY WEST, Fla. - A state of emergency was declared for all of Florida today as the one-two punch of a tropical storm and then a hurricane raged closer, the first time the state has faced such a potentially messy plight in almost a century.

Tropical Storm Bonnie was forecast to hit the state this afternoon, and Hurricane Charley early Friday. Schools and government offices were closed, and Gov. Jeb Bush activated the Florida National Guard.

Tropical storm warnings were posted along the Panhandle for Bonnie. For Charley, hurricane warnings and watches were posted for the Keys and the state's southwest coast. A steady line of traffic drove north off the Keys late Wednesday as tourists followed orders to evacuate the entire 100-mile-long island chain. Officials expanded the order today to include a mandatory evacuation of mobile homes in the lower Keys.

Because the Panhandle is already soaked from days of rain, some low-lying areas there may have to be evacuated if there's flooding, said Craig Fugate, the state's emergency management director.

"Residents should make sure they're getting prepared," said Daniel Brown, a forecaster at the National Hurricane Center in Miami. "They're both something people should be watching."

Such a double-whammy hasn't happened in Florida since Oct. 17, 1906, when two tropical storms hit the state, said Ken Reeves, the senior meteorologist at AccuWeather, a commercial forecasting center.

According to Hurricane Center projections, both storms could spread rain along the East Coast after hitting Florida. For North Carolina, the heavy rain from the storms was coming just a week after Hurricane Alex damaged parts of that state's Outer Banks.

At 8 a.m., Bonnie was centered about 80 miles southwest of Apalachicola and moving northeast near 22 mph. Bonnie was expected to make landfall along the central Panhandle on Thursday afternoon, when isolated tornadoes were also possible, forecasters said.

The storm's maximum sustained winds were at 55 mph as of 8 a.m., down from 65 mph Wednesday. Bonnie could dump 4 to 6 inches of rain, leading to coastal storm surges 1 to 3 feet above normal, forecasters said.

A steady rain was falling at daybreak in Apalachicola in the Panhandle, expected to absorb a big part of Bonnie's brunt. There was only a light breeze, with storm-force winds not expected to arrive until later in the day.

Charley had top sustained winds of about 85 mph and was expected to strengthen. It was centered about 40 miles east of Grand Cayman, and was moving northwest near 16 mph.

Charley was expected to make landfall in Florida early Friday. A hurricane warning was issued in the Keys from the Dry Tortugas to the Seven Mile Bridge and in southwest Florida from East Cape Sable to Bonita Beach.

Charley was expected to remain at hurricane force when it passes over mainland Florida, forecasters said. Three to 6 inches of rain were expected, with higher amounts possible, Brown said.
