The National Weather Service office in Peachtree City, Georgia, has issued a Flash Flood Warning covering six counties in the greater Atlanta area: Cobb, DeKalb, Fulton, Douglas, Carroll, and Paulding. The warning was issued at 10:23 a.m. EDT on September 12 and remains in effect until 1:30 p.m. EDT.
A flash flood warning means flooding is happening now or is imminent — this is a step above a flood watch, which only signals that conditions are favorable. Heavy rain falling on already-wet ground or overwhelming storm drains can send water rising quickly on roads, in underpasses, and along small creeks and streams.
What you might notice
Residents in the warned counties may see water pooling on roads, rapidly rising streams, flooded intersections, and overflowing drainage ditches. Commutes could be disrupted, especially during the midday hours covered by this warning. Low-lying areas, underpasses, and roads near creeks are most at risk.
What to do
First, never drive through flooded roads — just 12 inches of moving water can carry away a small car, and most flash-flood deaths happen in vehicles. Turn around and find another route. Second, if you live near a creek or in a low spot, be ready to move to higher ground quickly, and keep phones charged with wireless emergency alerts turned on. Third, avoid walking through floodwater, which can hide open manholes, debris, and electrical hazards.
The warning is currently set to expire at 1:30 p.m. EDT, though it could be extended or reissued if heavy rain continues. This alert is based on official data from the National Weather Service office in Peachtree City, Georgia (NWS/NOAA).
Frequently Asked Questions
What should I do right now?
Avoid driving on flooded roads, stay off low-lying routes and underpasses in the six warned counties, and be ready to move to higher ground if water rises near your home. Keep emergency alerts enabled on your phone until the warning expires at 1:30 p.m. EDT.
How long will this warning last?
The warning runs until 1:30 p.m. EDT on September 12, but NWS Peachtree City may extend or reissue it if heavy rain continues over Cobb, DeKalb, Fulton, Douglas, Carroll, or Paulding counties.
Is it safe to drive through water that looks shallow?
No. About 12 inches of moving water can sweep away a small car, and floodwater often hides washed-out pavement underneath. Turn around and take another route.
Does this affect my commute in Atlanta?
Possibly — Fulton, DeKalb, and Cobb cover much of the metro core, so expect flooded intersections, slow traffic, and possible road closures through early afternoon. Check conditions before leaving and allow extra time.
