The Twin Cities Superstorm, 1987
The downpour on the late night of July 23, 1987, marks the most important rainfall event in the history of Twin Cities. In just 6 hours, Twin Cities International Airport measured a 10- inches rainfall leading to massive flooding in the southern and western parts of the cities.
The rain is believed to have been a by-product of the interaction between the south and east warm, moist atmosphere, and the cooler, drier air of the north and west. The claim is further supported by the intense thunderstorms and the torrential downpour which has been experienced two days before this fateful day.
Severe flash flooding was experienced on the evening of July 23 as most major roads became swamped, and rivers burst their banks. This saw motorist hurriedly abandon their cars for higher ground as water levels rose past car rooftops. Roads were closed, bridges washed out, lives were lost, homes destroyed, and properties of significant value ruined.
