Florida Braces For Another Storm

(CBS/AP)  Florida Gov. Jeb Bush issued a state of emergency as tropical storm Katrina threatened to dump more than a foot of rain on parts of water-logged Florida as it approached the southern coast Wednesday, with forecasters expecting it to strengthen to a weak hurricane before hitting the coast.

Katrina was expected to strike Florida's east coast early Friday.

At 8 p.m. EDT, the season's 11th named storm had top sustained winds of about 45 mph. Katrina was centered about 165 miles east-southeast of the Florida coast and was moving west-northwest at 9 mph.

A 150-mile stretch of Florida's coast including Miami, Fort Lauderdale, West Palm Beach and Vero Beach was under a hurricane watch, meaning sustained winds of at least 74 mph were possible by Friday. The watch area also included inland Lake Okeechobee.

CBS News Correspondent Mark Strassmann says Katrina has a combination hurricane trackers like to see least: slow-moving and still developing over warm waters.

"There's some possibility that this is going to be a stronger storm by the time it gets to the coast. There's a lot of warm water, a very deep source of energy," WFOR-TV meteorologist Bryan Norcross says.

Many in the area, which endured two hurricanes last year, didn't seem too worried about the slow-moving storm whose worst threat appeared to be flooding. Hardware stores noticed a slight increase in sales, but there didn't appear to be a crush of customers looking for plywood, water and other supplies.

Katrina formed Wednesday over the Bahamas and was expected to cross Florida before heading into the Gulf of Mexico. It could dump 6-12 inches of rain in the state, with some spots getting up to 20 inches.

This is the 13th anniversary of Hurricane Andrew, reports CBS News Correspondent Peter King. It was the most expensive natural disaster in U.S. history. Katrina will be weaker, but wetter, dumping more than a foot of rain in some areas.

"We're uncertain on the intensity forecast. It still has a couple of days to intensify before it makes landfall," Eric Blake, a National Hurricane Center meteorologist, told King.
