CHICAGO (CBS) — Whether driving or walking, the heavy snowfall in the Chicago area will likely be a significant challenge for those looking to get out Sunday as the snow keeps falling.

Thick snow covered the area overnight, and the City of Chicago had around 300 salt spreaders and plows out clearing main roads. When that is complete they will move on to residential streets. Meanwhile, the Illinois Department of Transportation had more than 1,800 trucks and equipment out tackling the roads.

However, it is suggested to stay off the roads unless completely necessary.

Saturday night CBS 2 did find one person who was out and about making deliveries to those who decided to stay inside.

“It’s like really busy, and I’m doing a lot of orders,” said Uber Eats driver Tetyana Blyshak.

A winter storm warning is still in effect for the Chicago area until 6 p.m. Sunday. The system’s snow has lightened in intensity since Saturday but will continue to bring moderate to heavy snow at times.
