The entire D.C. area is under a winter weather advisory Wednesday as wintry mix creates major havoc on local roads.
Snow and sleet are making roads in Maryland particularly messy. Several accidents have been reported along I-70 in western Maryland, where total snowfall will be higher because of the mountains.
