August 28, 1990

Friday, August 28, 2020 marks 30 years since Plainfield, IL and adjacent communities of the far southwestern Chicago metro were struck by the strongest August tornado on record in the United States. That late summer day will long be remembered by residents of northern Illinois due to the lives the tornadoes took and the devastation it caused. This page serves as a collection of information from that event, including accounts shared by many public citizens, as well as a description of advances in meteorology, communication, and readiness over the past three decades.
