Soft slab avalanches could be human triggered on a variety of aspects. These slabs are expected to be up two feet deep and sensitive to ski cuts.

Highlights
In some areas over two feet of new snow has fallen in the past several days. Soft slabs up to two feet in depth and loose snow sluffs are likely to be triggered by humans in steep avalanche prone terrain, especially at the higher elevations (above an elevation of 9,000 feet). These loose snow sluffs and soft slab avalanches are especially dangerous in cliffs areas and above terrain traps. Expert route selection skills and conservative terrain choices are important today.

Deep hard slabs could be human triggered above an elevation of 9,000 feet in steep north facing avalanche paths. If triggered these dangerous slabs could involve the full depth of the snowpack. These deep slabs are more likely to fail with larger triggers such as snowmobiles, large cornice drops or groups of people.

Loose snow sluffs could be human triggered or release naturally in steep terrain at all elevations. These sluffs could entrain significant volumes of loose snow and run long distances on steep sustained slopes.
Avalanche Discussion
( Discussion is generated from the previous day's afternoon forecast. )Periods of snow will continue overnight and into Tuesday afternoon. Additional accumulations of 4 to 8 inches are likely by Tuesday evening. Temperatures will be in the single digits and teens. Winds will back to the northeast at speeds of 10 to 20 miles per hour.Soft surface slabs will continue to gain depth and volume. Changing wind directions will distribute these slabs onto a variety of aspects. Loose snow sluffs will continue to be a hazard in steep terrain and will also become more significant with respect to size and distribution. Soft slabs up to two feet in depth and loose snow sluffs are likely to be easily triggered by humans in steep avalanche prone terrain, especially at the higher elevations in the forecast areas that have received the most new snowfall. Natural avalanche activity is possible in those favored areas. The general avalanche hazard is expected to be CONSIDERABLE at the upper elevations of the Greys River and Teton areas and MODERATE at the mid and lower elevations of those forecast region and in the Togwotee Pass area. Deep slab avalanches continue to be a hazard on northerly aspects above an elevation of 9,000 feet in the Togwotee Pass and Greys River areas.
