Wake from a car passing by causes canoe-paddlers to capsize in St.Petersburg, Fla., as flooding continues to worsen and Tropical Storm Debby pounds the Tampa Bay area.

Underscoring the storm's unpredictable nature, forecasters discontinued a tropical storm warning for Louisiana after forecast models indicated Debby was less likely to make a westward turn than initially predicted. Coastal Alabama and parts of Florida, including the Panhandle, remained under tropical storm warnings.

Debby already had dumped heavy rain on parts of Florida and spawned some isolated tornadoes, causing some damage to homes and knocking down power lines. High winds forced the closure of an interstate bridge that spans Tampa Bay and links St. Petersburg with areas to the southeast.
