The Federal Aviation Administration (FAA) issued a ground stop at Hartsfield-Jackson Atlanta International Airport on July 12, 2026, initially until 2:30 p.m. due to severe thunderstorms. This ground stop was extended until 4 p.m. before expiring later that afternoon. At 8:10 p.m. the FAA reinstated a second ground stop at the airport, which lasted until 9 p.m.
Severe Weather Warnings Across Eastern Georgia
During this period, several counties in eastern Georgia were placed under severe thunderstorm watches and warnings. The watch, active until 9 p.m., included counties such as Baker, Berrien, Brooks, Calhoun, Clay, Colquitt, Cook, Decatur, Dougherty, Early, Grady, Lanier, Lee, Lowndes, Miller, Mitchell, Quitman,
Randolph, Seminole, Terrell, Thomas, Tift, and Worth. Specific warnings were issued for Habersham County until 6:15 p.m., and for Morgan, Newton, Oconee, and Walton counties until 4:45 p.m.
Flight Delays and Operational Impact
As of approximately 1 p.m. on July 12, the FAA reported over 900 flight delays at Hartsfield-Jackson Atlanta International Airport. The average delay duration was around 40 minutes, with the longest delay recorded at 75 minutes. These disruptions were a direct consequence of the thunderstorm-related ground stops imposed by the FAA, which paused flight departures temporarily.
The FAA indicated there was a 30 to 60 percent probability of further extensions to the
ground stop during the day. The severe weather condition and its impact on airport operations caused significant disruptions to flights departing from one of the busiest airports in the United States.
Meteorologist Eboni Deon from Severe Weather Team 2 earlier forecasted a chance of scattered or isolated severe storms on the afternoon of July 12, 2026, which coincided with the ground stop events.
