Tetons

At the mid and upper elevations southwest winds have formed soft surface slabs up to 30 inches deep. These slabs could be human triggered on steep slopes. In addition deep hard slabs up to five feet in depth lie upon hard crusts. These dangerous slabs could be human triggered on very steep slopes, especially by larger triggers such as groups of people or snowmobiles. At the lower elevations avalanches are unlikely except in isolated pockets on road cuts or steep banks.

A very cold air mass with a strong northwest flow will remain over the area through Thanksgiving Day. Limited moisture in the flow will keep variable clouds and light snowfall or flurries at times over the mountains. Temperatures will rise to near zero from overnight lows near 20 below zero. Winds will west-northwesterly at 25 miles per hour at the summit level. The general avalanche hazard is expected to be MODERATE at an elevation of 7,500 to 10,500 feet and LOW below an elevation of 7,500 feet. At these higher elevations dense wind slabs up to two feet deep and dangerous hard slabs up to four feet in depth exist in cliff areas and the starting zones of active avalanche paths. People, especially those in groups or on snowmachines, could trigger these slabs. Avalanches are unlikely at the lower elevations.
