Heavy rain from thunderstorms prompted a flood advisory for northern Volusia County until 4:45 p.m. Thursday in Volusia County and 5 p.m. in Flagler, according to the National Weather Service in Melbourne.
"Up to two inches of rain have already fallen, with an additional one to two inches possible," said NWS meteorologist Jesse Smith.
Smith said that some locations that will experience flooding include Daytona Beach, Port Orange, Ormond Beach, New Smyrna Beach, South Daytona, Palm Coast, Flagler Beach, Marineland and Beverly Beach. A few stronger storms will be possible, forecasters said, producing frequent lightning strikes and strong wind gusts up to 40 mph.
Excessive runoff from heavy rainfall may cause flooding of small creeks and streams, urban areas, highways, streets and underpasses as well as other drainage areas and low lying spots, forecasters said.
Scattered showers and storms are expected this afternoon through the early evening, forecasters said, with storms moving slowly east to southeast across the region and offshore.
A marine warning is in effect for Volusia and Flagler counties until 3 p.m. with forecasts of wind gusts 34 knots or greater.
"Additional storms will develop over the mainland and push off of the Volusia and Brevard coasts this afternoon," said NWS meteorologist Tim Sedlock.
The NWS reminded residents to turn around rather than drive through flooded roads. "Most flood deaths occur in vehicles," Smith said.
Scattered to numerous thunderstorms are expected through the afternoon and evening hours for the rest of the week and into the weekend, forecasters said. A few stronger storms will continue to be possible each day, producing frequent lightning strikes, strong gusty winds and locally heavy rainfall.
