The latest winter storm to hit the Chicago area is causing problems on the highways and streets across the city and suburbs.
Commuters are cautioned to leave early and take it slow, as the snow has already piled up, creating slick creations.
The Illinois Department of Transportation , Illinois Tollway and the city of Chicago have their entire fleets of snow plows working overnight and throughout the morning to clear the roads.
The Chicago area remains under a winter storm warning until 1pm Wednesday.
The heaviest snowfall, possibly up to 10 inches, is expected to fall to the south of Chicago.
Anywhere from 4 to 8 inches are expected across much of the area, though some places along the Wisconsin border may see only 1 to 3 inches.
High winds are creating near white-out conditions in some portions of Will, Cook and Kane Counties.
Metra is implementing its winter weather plan, spokeswoman Meg Reile said.
Metra will put extra train crews in place to make up for staffing shortages or emergencies. Metra brought in other crews at 1 a.m. to get a head start on clearing and salting platforms in advance of the rush hour.
Metra will also modify its system of alerts that are posted on the website and sent via email and Twitter.
Instead of posting or sending out single-train alerts, as it has in the past, Metra will condense these by line so customers are not swamped with information they might not need, Reile said.
This winter is the fourth snowiest on record but Wednesday’s snowfall could move this winter’s total into third place after the storm, maybe even second.
A total of 75.5 inches of snow has fallen so far this season, behind the 77 inches of 1969-70, the 82.3 inches of 1977-78 and the 89.7 inches of 1978-79.
