January 10-11, 2020: Storm System Brings Most Significant Lakeshore Flooding in Years, Heavy Rain, and Wintry Mix

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.

Lakeshore Flooding

Lakeshore flooding was so significant on Saturday, January 11 because of 1.) the duration (~18-21 hours) of strong north-northeast winds that were oriented along the maximum fetch of the lake and 2.) near-record high lake levels.

This was the most impacting flooding of northeast Illinois shores since at least Oct 31, 2014, but for some areas likely much further back than that.

A Lakeshore Flood Watch had been issued early on the morning of January 9 (48 hours of lead time) and upgraded to a warning that evening (30-36 hours of lead time).

Hourly loop of modeled wave heights from 3 a.m. through 7 p.m. on January 11.
