A National Weather Service flash flood watch for Rockdale County remains in effect until late Saturday night.

The flash flood watch extends over the northwestern half of the state. A flash flood warning is in place for most of the metro-Atlanta area.

"A strong upper level system and associated cold front will move into Georgia tonight. A backdoor cold front will stall across northeast Georgia this evening," the warning reads.

About 2 to 3 inches of rain are expected in the flood watch areas, with 4 to 5 inches in the north Georgia mountains and western and northern area of Atlanta.

Because the soil is still saturated from the record rainfall over the last week, "any heavy rain that develops will run off into creeks and streams, leading to rapid rises," the statement warns. The water rises are not expected to be as significant as what occured earlier in the week."
