The Federal Aviation Administration lifted a ground stop at Hartsfield-Jackson Atlanta International Airport but converted it into a ground delay program lasting until 9:59 p.m. on September 11, 2026. Arrival flights faced average delays of 107 minutes, with some delayed as long as 271 minutes. Initial departure delays averaged about 45 minutes before increasing amid ongoing thunderstorms.
Flooding Shutdowns Disrupt Airport Access
Heavy floodwaters closed the Interstate 285 westbound ramp to Interstate 85 southbound in Fulton County, directly affecting access to the airport. Rising water also rendered the GA 400 stretch near Northridge Road in Sandy Springs impassable. Additional flooding blocked roadways at Courtney Drive
near Finley Drive in Clayton County. These closures were part of flash flood warnings issued by the National Weather Service covering Clayton, DeKalb, Fulton, Carroll, Douglas, Haralson, and Paulding counties until 10:30 p.m., with rainfall totals ranging from 1.5 to 4 inches during the storms.
Flight Operations Hit by Severe Delays at World’s Busiest Airport
Hartsfield-Jackson Atlanta International Airport, handling 106.3 million travelers in 2025, experienced significant disruption due to the weather-driven ground stop and delays. The initial ground stop, extended from 4:45 p.m. to 5:45 p.m., halted all arrivals from 10 major air traffic control centers spanning the eastern, central, and southern United States. The FAA’s transition to a
ground delay program prolonged wait times, with flight delays reaching up to 271 minutes for some arrivals.
Extreme Weather Conditions Fueled Flooding and Delays
The regional storm system produced heat index values in the upper 90s to low 100s combined with extreme moisture, resulting in slow-moving thunderstorms that caused persistent heavy rainfall. These conditions led to standing floodwater blocking critical highways near the airport. The National Weather Service Forecast Office in Peachtree City manages weather alerts for a 96-county area, including all of Metro Atlanta, providing continuous flood warnings and river forecasts throughout the event.
Official Warnings on Flood Safety
The Georgia Department of Transportation cautioned that as little as 12 inches
of moving floodwater can displace vehicles. Both the department and the National Weather Service strongly advised drivers to obey barricades and not attempt to cross flooded roads. Traffic and road closures caused by flooding continue to affect ground transportation options to and from Hartsfield-Jackson Airport today.
Regional Impact of Hartsfield-Jackson’s Size on Delays
As the world’s busiest passenger airport, Hartsfield-Jackson’s handling of 63.1 million scheduled flight seats in 2025 generates extensive regional air traffic coordination. Holding inbound aircraft across 10 regional air traffic control centers due to the ground stop compounded delays, creating ripple effects across multiple states. The disruptions mark the latest weather-related impacts to Metro
Atlanta, following previous severe weather and outage events this year.
