Strong winds force O'Hare runway closures, delays

High winds have shut down most of O'Hare International Airport's runways, causing arrival delays of more than two hours on average.

The Chicago Tribune reports that the airport is landing arriving aircraft on two diagonal runways that are used in crosswind weather conditions.

The Federal Aviation Administration said the other five east-west parallel runways were closed Wednesday until conditions improve.

According to the tracking website, more than 270 flights in and out of O'Hare were canceled by midday Wednesday.
