Salt River and Wyoming Ranges

The general avalanche hazard is HIGH. New snow and strong winds have created dangerous unstable conditions. Large natural avalanches are likely and could run full path. Travel in avalanche terrain is not recommended.

( Discussion is generated from the previous day's afternoon forecast. )Widespread light to moderate snowfall will continue through the night and into Friday morning. Heavy snowfall is expected in the Teton and Gros Ventre Ranges Thursday evening and will shift into the Salt River and Wyoming Ranges around midnight. Winds accompanying this storm system will generally be west with gust to 50 miles per hour. New snow accumulations through Friday morning are expected to range from 8 to 13 inches in the mountains and 3 to 7 inches in the valleys. The snowfall will taper to snow showers by Friday afternoon. Mountain temperatures will remain in the single digits. With heavy snowfall and strong winds in the forecast the general avalanche hazard is expected to increase to HIGH. Surface slabs up to three feet in depth are likely to be easily triggered by humans on steep avalanche prone slopes and could release spontaneously. Dangerous deep hard slabs are possible in areas with a persistant weak base layer of faceted snow.
