On August 4, 2026, the National Weather Service issued a flash flood warning for southeastern Cobb and central Fulton counties in Georgia as thunderstorms produced heavy rain expected to accumulate between 2 and 4.5 inches in a short time. Doppler radar detected the severe weather prompting the Federal Aviation Administration to impose a ground stop at Hartsfield-Jackson Atlanta International Airport as a precaution against hazardous conditions affecting the metro Atlanta area.
The flash flood warning remained active until 3:45 p.m. local time, threatening flooding in low-lying areas that impacted transportation and airport operations. Although the FAA lifted the ground stop
before 1:04 p.m. EDT, departures from Hartsfield-Jackson Atlanta International Airport faced average delays of 105 minutes, causing extended wait times for travelers in the region.
