The City of Chicago has deployed its full fleet of 280 snowplows and salt spreaders and will focus on clearing Lake Shore Drive and arterial streets before plowing residential streets, according to a statement from Mayor Rahm Emanuel's office.
"Our city is tackling the first major snow storm we have seen in several years - and it's clear that Chicagoans are rising to the challenge," Emanuel said in the statement. "I ask everyone to keep exercising good judgment and remain indoors if at all possible, to take the warnings and advisories seriously, and to check on the well-being of family, friends and neighbors."
The Cook County Department of Transportation also planned to deploy its full fleet of snowplows and salt trucks in preparation for the start of the storm, the county said in a statement.
County officials and the Illinois Department of Transportation are advising against non-essential driving and urging drivers to yield to snowplows and leave a safe distance between their vehicles and plows.

In addition, more than a thousand flights were canceled at the city's airports, and transportation agencies were warning commuters of the storm's impact.
As of 3:50 p.m. Friday, 999 flights had been canceled at O'Hare and 316 flights had been canceled at Midway, according to the Chicago Department of Aviation. Delays at O'Hare were averaging 59 minutes, while delays at Midway were averaging less than 15 minutes.
