Thousands of Chicagoans have filed service requests to the city for snow and ice removal on sidewalks, roads and bike lanes after this winter kicked off with the most snow in the area since 1978.

Overnight Chicago-area snowfall created hazardous road conditions and caused delays at Chicago O'Hare International Airport on Sunday.

So far, 17.1 inches of snow has been recorded in Chicago as of Dec. 7. During the entire 2024-25 winter season just 17.6 inches of snow fell in the area. It marks the snowiest start to winter since 1978, according to NWS. That year, 24.1 inches of snow had fallen by Dec. 7.

Chicago has now seen more than 17 inches of snow this winter season — the quickest accumulation since 1978, according to the National Weather Service.

A Winter Weather Advisory has been issued for much of the Chicago area, as roads may become slick and snow-covered.

After snowy weekend, Chicago expected to receive up to another four inches of snow on Monday during evening rush hour.

The National Weather Service issued a winter weather advisory from midnight to 9 a.m. Sunday as the area could see between 3 to 5 inches of snow.
