August 13, 1987:

A succession of thunderstorms produced rainfall that was unprecedented in 116 years of precipitation records at Chicago, Illinois during an 18 hour period from the evening of the 13th to the early afternoon of the 14th. The resulting flash flood was the worst to ever strike the Chicago metropolitan area, causing 3 deaths and water damage that amounted to 221 million dollars worth. O Hare International Airport received an event total of 9.35 inches of rain in 18 hours, shattering the previous 24 hour record of 6.24 inches. For a period of about 24 hours, the airport was only accessible from the air as all roads were blocked by high water, including the Kennedy Expressway.
