Salt River and Wyoming Ranges

The general avalanche hazard remains MODERATE above an elevation of 8,000 feet. Areas of unstable snow persist in steep, avalanche-prone terrain. Hard slabs to 30 inches in depth lie on a base of weak, faceted snow. Slides could be triggered by the first person on a slope or after a slope has been crossed multiple times.Evaluate terrain and snow stability carefully. Backcountry travelers have triggered avalanches in the Tetons over the past two days in steep, rocky terrain and similar events should be expected in the Greys River/Southwest Trails area. At the lower elevations the general avalanche hazard is LOW.

( Discussion is generated from the previous day's afternoon forecast. )A disturbance in the westerly flow will bring light snow to the region overnight and continuing into Wednesday. Accumulations of three to four inches are forecasted by Wednesday evening. Morning lows will be in the single digits then warm only to around ten degrees during the day. Exposed ridge tops will have southwest to westerly winds of 15 to 20 miles per hour. The General Avalanche Danger will continue at MODERATE above 8,000 feet due to areas of persistent unstable snow. Light density forecasted snow will not likely create a higher hazard unless winds pick up to cause significant drifting. Backcountry travelers on steep, avalanche terrain could trigger a hard-slab avalanche to three feet in depth. These slides could be started by a single person or after a slope has been crossed multiple times. Persistent hard slabs are sometimes triggered lower on a slope than softer slabs. Recent slides have had areas nearby with shallow, cliffy terrain where accelerated faceting has occurred. At the lower elevations the general avalanche hazard is LOW and avalanches are unlikely.
