The National Weather Service has issued a winter weather advisory for this evening into Wednesday in anticipation of blowing snow that could cause hazardous travel conditions.

The advisory will go into effect at 9 p.m. Tuesday and end at 3 p.m. Wednesday.

The advisory will cover portions of north-central and northeast Illinois, including Winnebago, Boone, McHenry, Lake, Ogle, Lee, DeKalb and Kane counties.

Blowing snow is expected with the potential for “severely reduced visibilities” in open areas and snow drifting onto previously cleared roads, the NWS said.

Hazardous travel conditions are expected to develop in open areas particularly late Tuesday into Wednesday.

Pockets of near white-out conditions could develop along north-south roadways where unobstructed western exposure allows snow to blow across the roadway, the NWS said.

Strong southerly winds could result in blowing and drifting across east-west roadways in open areas Tuesday evening.

Conditions will “deteriorate significantly” late Tuesday as very strong west winds result in significant blowing and drifting snow across north-south roads, the NWS said.

Some potential exists for near-ground blizzard conditions to develop in open areas, the advisory said. People traveling in rural and outlying areas are suggested to postpone unnecessary travel.
