Event narrative (NOAA)
After heavy rain and flash flooding across much of southern Cook County from the early morning through the afternoon of September 13th, flooding continued across many locations through the evening hours and into the early morning hours of September 14th, when another wave of heavy rain moved across the area. A elderly man fell head first into a flooded window well and drowned in Oak Lawn. He was trying to clear a plugged drain in the window well.
