Severe Weather Forces Airport Operational Measures
Severe storms swept across Illinois and Indiana on August 11, 2026, triggering the FAA’s ground stops. The weather system brought intense wind gusts reaching up to 100 miles per hour, brief tornadoes, and heavy rainfall to the Chicago area. These conditions resulted in downed trees and power lines along with issued
flood warnings.
The Chicago Department of Aviation confirmed the control tower at Midway Airport was temporarily evacuated during the storm event, disrupting airport operations. NBC 5 meteorologist Kevin Jeanes reported the storm’s intensity and path through the region.
FAA and Local Authorities’ Response
The FAA indicated the ground stop at O’Hare could be extended depending on storm progress. Following the ground stop, the agency implemented a ground delay program at O’Hare that will remain active until 10 p.m. CT to manage flight arrivals and departures safely.
The Chicago Department of Aviation provided additional confirmation of the Midway tower evacuation, emphasizing safety precautions during the severe
weather. The ground stops were enacted primarily to safeguard air traffic and airport personnel from the hazardous storm conditions.
Flight operations were significantly impacted as departures to Chicago were temporarily halted, causing delays and cancellations. The ground delay program at O’Hare will continue to restrict departures throughout the rest of the day.
