CHARLESTON COUNTY, SC - The National Weather Service has issued a flash flood watch until 5 a.m. on Thursday for Charleston and tidal Berkeley.
A flash flood watch means there is potential for flash flooding based on current forecasts.
An earlier flash flood warning for Berkeley, Colleton, Charleston and Dorchester counties expired late Wednesday night.
At 8:23 p.m. on Wednesday, NWS doppler radar indicated extremely heavy rain extending from Cottageville to downtown to Isle of Palms. Nearly 6 inches of rain had fallen at the Mount Pleasant Regional Airport.
The Charleston Police Department says the following streets are having traffic diverted due to flooding: Huger and King Streets and Ashley Avenue north of the Crosstown.
The risk for flash flooding will increase with high tide in progress.
Avoid driving into water on the road. The water is usually deeper than it appears and the road may be washed out. Only one foot of water will stall a vehicle and less than two feet of water can float and carry away a vehicle.
South Carolina Electric and Gas was also called out to a lightning strike on a power line that occurred during the storm Wednesday night at Sam Rittenburg Boulevard and Orange Grove Road. Residents lost power temporarily in that area while crews worked to get the power restored.
