The National Weather Service issued a winter weather advisory for Washtenaw County that goes into effect 8 p.m. Tuesday and lasts until 7 a.m. Wednesday.

A clipper system expected to bring two to four inches of snow to the region triggered the advisory, which warns that heaviest accumulations are expected between 10 p.m. and 2 a.m.

According to the advisory, snow-covered roads and reduced visibilities overnight could result in hazardous travel conditions. The additional snow could also compound any issues caused by the 14-plus inches that fell on the region over the weekend.
