The National Weather Service out of Columbia has issued a Flash Flood Watch for Clarendon County and surroundingn areas from 8 p.m. Sunday through 8 p.m. Monday. Rainfall associated with a developing low pressure system will become widespread and heavy tonight, and persist into early Tuesday. Periods of very heavy rain will contribute to total rainfall of 2 to 4 inches, with isolated higher amounts possible.
Grounds will become saturated as periods of heavy rainfall move across the area. This has the potential to lead to flash flooding, especially in locations with poor drainage such as urban areas or in and around culverts. Excessive roadway ponding is also likely, and at times some roads may become impassable, especially if drainage ditches overflow onto roadways.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
