Some counties will be under a winter storm warning overnight while others are under a winter weather advisory.
A powerful storm is on the horizon, but there's still plenty of uncertainty surrounding the storm's path and what it will mean for parts of the Chicago area. Still, ice, snow and localized blizzard conditions are all possible as officials warn of hazardous travel conditions across the state.
The Illinois Department of Transportation said a "major storm" is expected to bring heavy rains, flooding, double-digit snowfalls, ice and high winds, all of which will "create slick conditions, impacting travel across much of the state."
“The Illinois Department of Transportation’s snow-and-ice teams will be prepared and out in force, but the public needs to be ready for conditions to change quickly and worsen if they are out on the roads,” Illinois Transportation Secretary Omer Osman said in a statement. “As always during periods of extreme weather, the safest option is to postpone any unnecessary trips and stay home. If you must travel, prepare for very slow and potentially hazardous conditions. And please slow down around our plows and other emergency vehicles, giving them plenty of room to do their jobs.”
