Salt River and Wyoming Ranges

The general avalanche hazard is CONSIDERABLE. Dangerous, deep, unstable slabs rest upon a base of weak, faceted snow. Recent snow and winds have added weight to these slabs, increasing their likelihood of failure. Backcountry travelers venturing onto these dangerous slabs could easily trigger them, or these slabs could be triggered from a distance. If initiated, these slabs could run full track. Six to twelve inch deep surface slabs lying upon good sliding surfaces, along with loose snow sluffs, could also be triggered in steep, wind-loaded terrain.

( Discussion is generated from the previous day's afternoon forecast. )Partly to mostly cloudy skies are forecasted for Wednesday with no precipitation and daytime highs at 9500 feet reaching the low teens after overnight lows 5 to 10 below zero. Winds overnight Tuesday into Wednesday morning will be strong from the north then east at 20 to 25 miles per hour. Steep thermal inversions will hold frigid air in the valley floors. Loose sloughs will continue to be the primary concern of backcountry travelers but strong upper elevation winds may develop easily triggered soft slabs on lee slopes. Once started, slabs will have the potential to pull out large amounts of loose snow and result in deep deposition. The general avlanche danger is expected to be Moderate on Wednesday in the Teton and Togwotee Pass areas. In the Greys River area deeper, hard slabs continue to be more sensitive to triggers and have the potential to run full path. The hazard there will be Considerable.
