The Federal Aviation Administration (FAA) lifted a ground stop at Hartsfield-Jackson Atlanta International Airport on Friday, September 11, 2026, but delays persisted with average arrival delays reaching 107 minutes and some flights delayed up to 271 minutes. The FAA issued the ground stop initially from 4:45 p.m. to 5:45 p.m. amid severe weather conditions, then replaced it with a ground delay program that lasted through 9:59 p.m., affecting flights arriving and departing from the airport.
Flood-Related Road Closures Impact Metro Atlanta Transportation
Heavy rainfall between 1.5 and 4 inches caused standing floodwaters that closed several key routes near the airport. The Georgia Department of Transportation shut down
the Interstate 285 westbound ramp to Interstate 85 southbound in Fulton County due to inundation. GA 400 near Northridge Road in Sandy Springs and the roadway at Courtney Drive near Finley Drive in Clayton County became impassable because of rising floodwaters. Flash flood warnings were active until 10:30 p.m. across multiple Metro Atlanta counties, including Fulton, DeKalb, Clayton, Carroll, Douglas, Haralson, and Paulding.
Hartsfield-Jackson’s High Traffic Volume Amplifies Delay Effects
As the world’s busiest passenger airport, Hartsfield-Jackson handled 106.3 million travelers and offered 63.1 million scheduled flight seats in 2025, spanning over 4,700 acres. The sheer volume of flights arriving from 10 regional air traffic control centers
magnifies operational disruption during severe weather events. The FAA’s ground stop and subsequent delay program created cascading delays affecting numerous flights scheduled during the storm.
Travelers Experience Extended Delays and Ground Transport Disruptions
Despite the FAA lifting the ground stop, passengers faced delays near two hours on average for arriving flights, with some waiting over four hours. Road closures from flooding added challenges for ground transportation access to and from the airport, contributing to congestion and logistical complications for travelers. The ongoing backlog at the airport sustained flight disruptions well after the ground stop ended.
Official Flood Warnings and Transportation Advisories Remain in Effect
The National Weather Service maintained flash flood warnings until 10:30 p.m. across seven
counties around Metro Atlanta, cautioning residents about flooded roads and swollen streams. The Georgia Department of Transportation urged drivers to obey barricades, warning that as little as 12 inches of moving floodwater can carry away vehicles. These advisories accompanied the severe thunderstorms and heat index values recorded in the upper 90s to low 100s during the weather event.
