Will Rogers World Airport in Oklahoma City, Oklahoma, reopened this morning and power was restored after tornadoes passed through the area last night and passengers were evacuated into an underground tunnel until the threat subsided.

Early morning flights today were canceled, according to the airport’s Twitter account.

At least five people were killed and dozens injured when tornadoes and storms with high winds ripped through parts of Oklahoma and Missouri last night, according to published reports.

Will Rogers World Airport, which is owned by the City of Oklhahoma, handles more than 3.5 million passengers annually, with about 75 daily departures.
