The National Weather Service has issued a flash flood warning for portions of Richmond and Columbia counties.
The warning remains in effect until 7:15 p.m. in Richmond County and until 7:45 p.m. in Columbia County.
The warning was issued after the National Weather Service’s Doppler radar indicated a nearly-stationary thunderstorm producing heavy rain over North Augusta.
The warning is for northern Richmond County, including the city of Augusta, and eastern Columbia County, including Martinez and Evans.
Because the ground is already saturated, the heavy rain will lead to significant street flooding and flooding of other low-lying, flood-prone areas that include the Raes Creek and Reed Creek basins.
Excessive runoff from heavy rainfall will additionally cause flooding of small creeks and streams, urban areas, highways and underpasses.
