Fast Facts

  • A multi-faceted, large storm system brought numerous impacts to northern Illinois and northwest Indiana, including heavy rain and localized flooding, followed by strong winds and the most significant lakeshore flooding in the Chicago area in years. There also was occasional wintry precipitation including icing.
  • North to northeast winds frequently gusting to 40-50+ mph in Chicago throughout Saturday, January 11, brought large, battering waves into shore line areas and significant flooding resulting in the closure of Lake Shore Drive. The winds also resulted in major aviation impacts in the Chicago area, and O'Hare International Airport was forced to have around 1,000 cancellations.
  • Rainfall of 1.5 to 3" across much of the area on Friday night, January 10, resulted in rapidly rising rivers into flood stage. Wintry precipitation also impacted the area, including icing and some snow that resulted in slick roadways.
