CASPER, Wyo. — Winter weather advisories are in effect with 5-12 inches of snow expected in western and southeastern mountain ranges beginning  Monday evening through Tuesday, according to the National Weather Service (NWS) in Riverton.

There will be “hazardous mountain travel due to icy, snow-packed roads and reduced visibilities in falling and blowing snow,” the NWS said. “Outdoor recreation will be hazardous to those caught unprepared for winter conditions.”

In the western mountains, the advisory is in effect from 6:00 p.m. Monday through 2:00 a.m. Tuesday. Periods of snow, heavy at times, could bring 5 to 10 inches across the Gros Ventre Range and 6 to 12 inches in the Teton Mountains.

The Wind River Range will see strongest impacts between 8:00 p.m. Monday and 4:00 a.m. Tuesday.
