After a series of severe tornadoes and thunderstorms hit the greater Chicago area, causing significant disruption, operations at O’Hare International Airport returned to normal once the storms had passed.
On Wednesday, the region experienced multiple tornadoes, leading to the temporary suspension of air traffic at O’Hare International and Midway airports. Tornado sirens sounded in Chicago, prompting urgent calls for residents to seek shelter. Four counties in Illinois, including Cook County where Chicago is located, were affected by eight tornadoes.
As a result of the inclement weather, both O’Hare and Midway airports were forced to ground all commercial flights, resulting in cancellations and delays. FlightAware reported over 300 canceled flights at O’Hare and 32 at Midway. However, operations resumed as usual after the storms had subsided and weather conditions improved, according to the US Federal Aviation Administration (FAA).
