MANATEE -- River flood warnings remain in effect for the Manatee River at Myakka Head and the Little Manatee River at Wimauma, according to the National Weather Service, because of heavy rains in recent days.
Today's forecast suggests those warnings should be heeded.
At 1:30 p.m., the Weather Service reported that scattered showers and thunderstorms had developed along the sea breeze front along the western portions of Manatee and Sarasota counties.
"Heavy downpours and dangerous lightning are expected with these storms," the Weather Service said. "These storms are moving slowly eastward and will affect areas along Interstate 75."
Earlier, the Weather Service said there is 30 percent chance of showers and thunderstorms in Bradenton, mainly before 3 p.m.
Otherwise, skies will be partly sunny, with a high near 89 and northwesterly winds of 8 to 10 mph.
Tuesday evening, the chance of rain drops to 20 percent before 2 a.m. Wednesday. Skies will be mostly cloudy, with a low around 75.
The river flood warning is in effect until just after 8:30 p.m.
"Heavy rains over the past several days has caused local rivers to rise above flood stage," the Weather Service said.
The Weather Service advised motorists to not drive cars through flooded areas, and to listen to NOAA weather radio for the latest developments.
