Large, deep hard slab avalanches continue to be a potential hazard in steep, north facing terrain above 9,000 feet. A chance also persists for humans to trigger isolated pockets of wind slab in very steep, avalanche prone slopes. Evaluate the snowpack and terrain carefully, and identify features of concern.
Deep hard slabs continue to have potential to 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 under larger triggers such as snowmobiles, large cornice drops and groups of people.
( 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.
