A woman was found slumped over at a bus stop in a southwest neighborhood of Chicago during the late afternoon of Monday, August 8th. She was taken to the hospital where she was pronounced dead. The high temperature at Midway Airport on the 8th was 92 degrees.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
