The National Weather Service office in Peachtree City, Georgia, issued a Flood Warning for Cobb County on September 12 at 12:32 PM EDT. A Flood Warning means flooding is already occurring or is imminent in the warned area – this is a step beyond a Flood Watch, which only means conditions are favorable for flooding.
Residents in Cobb County, which includes communities such as Marietta, Smyrna, Kennesaw, and Powder Springs, may notice rapidly rising water on roads, creeks, and in low-lying areas. Urban and small-stream flooding is the most common threat in this part of metro Atlanta, where heavy rain can overwhelm drainage systems quickly. Underpasses, parking lots, and roads near creeks like Sope Creek and Nickajack Creek are typical trouble spots during events like this.
What you should do
If you are in the warned area, keep these points in mind:
– Never drive through flooded roads. Just 12 inches of moving water can carry away most cars, and 2 feet can sweep away SUVs and trucks. Turn around, don’t drown.
– Move to higher ground if you live in a flood-prone spot, and avoid basements or lower levels if water is rising nearby.
– Keep an eye on local NWS updates and county emergency alerts, as the warning may be extended or upgraded if rainfall continues.
Most flood warnings of this type remain in effect for several hours, until water levels recede. Continue to avoid flooded areas even after the rain stops, as creeks and streams can keep rising for a while afterward.
This alert is based on data from the National Weather Service (NWS) office in Peachtree City, Georgia.
Frequently Asked Questions
What should I do right now?
Avoid driving through any water-covered roads, stay away from swollen creeks and drainage areas, and move to higher ground if your home is in a low-lying spot. Monitor NWS Peachtree City updates and local emergency alerts until the warning expires.
How long will this flood warning last?
Flood warnings typically stay in effect for several hours, until observed flooding recedes. The NWS will update, extend, or cancel the warning as conditions change, so check for the latest statements this afternoon and evening.
Is it safe to drive in Cobb County right now?
Use caution and expect water on roads near creeks, underpasses, and poor-drainage areas around Marietta, Smyrna, and Kennesaw. If you encounter a flooded road, turn around – the depth and speed of the water are easy to misjudge.
Will the flooding get worse?
That depends on whether additional heavy rain falls over the same areas. Creeks and streams can continue rising even after rain tapers off, so conditions should be monitored until the NWS officially cancels the warning.
