Major Flooding at Detroit Metro Airport, McNamara Terminal Inaccessible.

August 24, 2023: Heavy rain overnight caused significant flooding at Detroit Metro Airport, leaving the McNamara Terminal inaccessible and stranding travelers.

A combination of heavy rain and storm runoff caused the flooding. According to the National Weather Service, three inches of rain fell on the airport over about five hours.
