The Federal Aviation Administration issued ground stops for all departures at Chicago’s O’Hare International Airport and Midway Airport on Thursday morning as thunderstorms and heavy rain moved through the region. The action, taken to preserve safety amid torrential downpours, affected travelers during the early rush hour.
At O’Hare, the ground stop was lifted at 7:15 a.m., ending the pause in departures after roughly two hours of delayed flights. Meanwhile, the halt at Midway was still in effect through at least 8:45 a.m., extending the disruption for a longer period. The FAA’s intervention reflects standard protocol when severe weather threatens visibility and runway conditions, allowing air traffic controllers to manage the situation safely.
Chicago experienced a bout of intense thunderstorms on September 17, bringing heavy rain that prompted the FAA’s precautionary measures. The agency’s ground stop orders are designed to prevent aircraft from taking off into hazardous conditions, reducing the risk of weather‑related incidents. By suspending departures, the FAA aims to keep both passengers and crew out of the most dangerous phases of flight until conditions improve.
Travelers at both airports faced an average delay of about two hours as the weather system moved across the city. The combined effect of the ground stops at O’Hare and Midway contributed to a noticeable slowdown in the morning travel schedule, underscoring the impact of severe weather on Chicago’s busy air travel network.
