Winter storm warnings and weather advisories from the National Weather Service are in place across six states due to expected snowfall, freezing rain, and hazardous road conditions.
Two states, Michigan and Indiana, have full warnings in place, while winter weather advisories have been issued for other parts of those two states as well as in New York, Tennessee, Minnesota, and Alaska.
These warnings, which include significant snowfall and icy conditions in some areas, have been put in place to advise residents of the potential travel difficulties and safety concerns.

A Winter Storm Warning indicates that heavy snow of at least 6 inches in 12 hours, or at least 8 inches in 24 hours, is expected. It can also be issued if sleet accumulation will be at least half an inch.
A Winter Weather Advisory is issued for one or more of the following: snow of 3 to 5 inches in 12 hours, sleet accumulation up to 1/4 inch, freezing rain in combination with sleet and/or snow, or blowing snow.
Here’s a breakdown of the latest updates by state:
