Cook County, IL–(ENEWSPF)– The Cook County Department of Homeland Security and Emergency Management issued a press release warning of, "Dangerous multifaceted and potentially life threatening winter storm Tuesday night into Wednesday."

The blizzard warning is in effect from 3 pm CST Tuesday to 3 pm CST Wednesday, the release said.

The release continues:

The National Weather Service in Chicago has issued a blizzard warning…which is in effect from 3 pm CST /4 pm EST/ Tuesday to 3 pm CST /4 pm EST/ Wednesday. The blizzard warning replaces the blizzard watch.

  • Timing…snow will increase in intensity and become heavy gradually spreading into northern Illinois by Tuesday evening. Snow…which will be heavy at times…will continue Tuesday night into Wednesday morning. Lake enhanced snow showers will continue near Lake Michigan in northeast Illinois Wednesday morning. Northeast winds of 25 to 40 mph with stronger gusts will result in blizzard conditions developing late Tuesday afternoon and continuing through the overnight hours.
  • Accumulations…snow accumulations in excess of a foot are expected over much of the area from Tuesday afternoon through Wednesday afternoon. Localized totals in excess of 18 inches remain possible…especially near the lake.
  • Hazards…white-out conditions are expected at times Tuesday night as very heavy snow and strong winds result in blizzard conditions. Snowfall rates of at least 2 to 3 inches per hour are possible…especially where thunder snow may be present.
  • Impacts…conditions will rapidly deteriorate from south to north across the region Tuesday afternoon…with travel likely becoming virtually impossible at times Tuesday night and into early Wednesday morning. Snow is expected to fall so heavily at times Tuesday night that plows may be unable to keep up with the snow…with many side streets and untreated roads becoming impassable.

Precautionary/preparedness actions:

A blizzard warning means severe winter weather conditions are expected or occurring. Falling and blowing snow with strong winds and poor visibilities are likely. This will lead to whiteout conditions…making travel extremely dangerous. Do not travel. If you must travel…have a winter survival kit with you. If you get stranded…stay with your vehicle.
