One of these weeks, your local National Weather Service office will dust off some winter weather advisories.

When they do, you'll be hearing some new winter weather road terminology from the Minnesota Department of Transportation.

  • Out? Subjective terms like "good, fair, difficult."

  • In? More descriptive winter road condition terminology like "partially covered" and "completely covered."

Here's a more detailed list of terms MnDOT will be using to describe winter road conditions this winter.

Progress.
