For the second time this week, the National Weather Service is warning you of potentially slippery conditions due to a winter storm.

Snow started in Door County at around 9 a.m., but the winter weather advisory does not officially kick in until 3 p.m. Lakeshore counties like Door, Kewaunee, and Manitowoc are expected to get hit the hardest with up to five inches of snow predicted. The combination of heavy snow, poor visibility, and covered roads will likely make travel conditions hazardous during the overnight hours. The winter weather advisory runs until 6 a.m. Friday.
