Tetons

Several inches of new snow has accumulated on surface hoar and slick old snow surfaces. Shallow, loose snow slides could be triggered by skiers and riders on very steep slopes on a variety of aspects. In addition shallow pockets of older wind slab up to one foot in depth could human triggered on steep slopes in isolated areas. On steep northerly aspects at the upper elevations faceted snow persist at the base of the snowpack. Although no hard slab avalanches have been triggered by skiers or riders in the Teton area on this basal layer, deep instabilities may persist in very steep rocky terrain and cliff areas that face north at the upper elevations.

Our area will be on the western fringe of a winter storm that is impacting areas to the east of the Continental Divide. Some light snowfall is possible overnight and could result in another inch or two of accumulation. On Monday the snow will taper off as skies begin to clear. Temperatures in the mountains will drop into the teens tonight and rise into the 20s on Monday. Winds will back towards the southwest and be light at 5 to 10 miles per hour.The general avalanche hazard is expected to remain LOW in the Teton and Greys River areas and in the Togwotee Pass area below an elevation of 9,000 feet. Loose snow sluffs are possible on very steep slopes and could entrain significant volumes of snow on long, steep sustained pitches. Small pockets of shallow soft slab, less than a foot deep, may form in isolated areas along the highest ridge lines. In the Togwotee Pass area the avalanche hazard at the upper elevations will be MODERATE. Human triggered hard slab avalanches with depths to three feet are possible in steep, rocky terrain that faces north above an elevation of 9,000 feet.
