The tropics are fulfilling predictions of an active stretch in the 2012 hurricane season, with two storms strengthening in the Atlantic Ocean and a third system showing signs of development in the northeastern Gulf of Mexico.
The National Hurricane Center on Wednesday gave the gulf system a 50 percent chance of becoming a tropical storm in the next two days. It would be named Nadine.
Several computer models show the system ultimately moving east over North Florida, probably by the weekend.
"We'll get some rain out of it for sure,'' said Bay News 9 meteorologist Mike Clay. "It's probably 50-50 if it becomes a tropical entity.''
Tropical Storm Leslie on Wednesday developed into a hurricane, the sixth of the season, the National Hurricane Center said. With sustained winds of 75 mph, Leslie is north of the Leeward Islands and moving north at 2 mph.
Forecasters think it could threaten Bermuda but is probably no threat to the U.S. mainland.
Tropical Storm Michael, located in the central Atlantic, is also threatening to become a hurricane, with sustained winds of 65 mph. It is moving northeast at about 6 mph and probably is no threat to land, forecasters say.
