A weekend blizzard blanketed the Midwest in snow and led to class being canceled at NIU, but classes resumed Tuesday.

The blizzard left more than a foot of snow in DeKalb and 22 inches by Lincolnshire, which was the highest accumulation in the state, according to Weather.com.

Here are the places commuting students can seek help when the roads are unsafe due to weather.

Where to look for traffic help

One resource for checking on the condition of roads is the Illinois Department of Transportation. IDOT uses an automated voicemail which reports on all highways across the state.

The blizzard stopping doesn’t mean the roads are safe. I-294 was subject to a multiple-vehicle crash that involved 40-50 cars Monday morning, and the accident was believed to be caused by “black ice,” according to CNBC.com.

Metra

Driving isn’t the only potentially dangerous method of commuting during winter weather as commuters in Chicago met trouble Monday as the Metra struggled with delays, according to WGNTV.com.

Check for weather

There are no active winter weather advisories, although there is expected to be more snowfall during the week. To check for weather advisories in the future, go to the National Weather Service website.
