South Carolina, Georgia face renewed threat of flash flooding after record rains slam Charleston

A Flash Flood Watch is in effect for much of southeast Georgia and South Carolina, including Charleston, through Saturday.

CHARLESTON, S.C.– A slow-moving cold front hanging over South Carolina and Georgia is bringing a renewed risk of flash flooding through the weekend. 

The almost-stalled front has plagued the South through most of the week. The strong flow behind Hurricane Erin allowed for pooling of atmospheric moisture along this nearly stationary front.

The combination of elevated moisture and instability allows for storms capable of producing very heavy rainfall.

Flood Watches were effect for much of Georgia and southern South Carolina, including Charleston, which Friday broke its daily rainfall record set in 2008. The city received 4.16 inches of rain, of which 2.25 inches fell in just a half hour.

The heavy downpours flooded dozens of roads throughout the Charleston area. Video from Charleston showed the progression of the flooding, with light rain and minimal street flooding to start off.

As the video progressed, the rain became heavier. Cars drove through badly flooded streets.

NOAA's Weather Prediction Center again issued a level 2 out of 4 flash flood risk for coastal areas in southeastern South Carolina and Georgia, including Charleston and Savannah, Georgia, for Saturday. Many areas will receive 1-2 inches of rain, but some isolated areas along the coast could see 4-6 inches of rain. 

FOX Weather Correspondent Katie Byrne reported from Charleston on Saturday morning, where heavy rainfall was falling once again.

"You're going to need an umbrella and your rain gear on, out today in Charleston," Byrne said.  

Byrne noted pools of water already from persistent downpours Saturday morning.

The fire district that services the Kiawah, Johns, Wadmalaw and Seabrook islands in South Carolina asked motorists to stay off the roadways due to flooding and washouts caused by the heavy rainfall.
