What You Should Do
Be especially cautious at night when it is harder to recognize the dangers of flooding. High tide will inhibit runoff of heavy rain, flooding areas of poor drainage in Downtown Charleston. Areas most prone to flooding include the Market, Crosstown, East Bay Street and Morrison Drive. Report flooding directly to the Charleston National Weather Service at 1-888-383-2024 or email nws.charlestonsc@noaa.gov.
Expected Conditions
At 9:23 PM EDT, Doppler radar indicated a large cluster of showers and thunderstorms with torrential rainfall. Much of the area received between 1 and 3 inches earlier this evening. Another 1 to 3 inches of rain could fall, which combined with high tide will likely produce areas of flash flooding, especially in parts of North Charleston and Downtown Charleston. Road closures are likely and water may enter buildings. Hazard: Flash flooding caused by thunderstorms. Source: Radar indicated.
