The advisory is in effect for southern portions of Gallatin, Madison, and Beaverhead Counties. Saturday morning the roads are expected to be slick and icy. The heaviest snowfall will be along the Montana-Idaho border during the day on Friday. These storms will be good for the snowpack in the local mountains which is below normal according to the United States Department of Agriculture. Currently, Gallatin County is 75% to the normal yearly average. The increased snowpack will also aid the local ski conditions at Big Sky Ski Resort and Bridger Bowl.
