Tetons

Yesterdays new snow and west to northwest winds formed new soft slabs one to two feet deep. Today's increasing west winds will continue to load these slabs. At the mid and upper elevations skiers or riders who venture into steep wind loaded avalanche starting zones could trigger these slabs. In steep rocky areas and near cliff bands these slabs have some potential to step down another foot or two into older layers of crusts and faceted snow. Avalanches are unlikely at the lower elevations except in isolated pockets.

Some light snow will fall over the western mountains mainly north of Alpine overnight with accumulations of three to six inches. On Friday skies will be cloudy with a couple inches of new snow in the morning hours, a break during the day and increasing snowfall by evening. Temperatures will be in the teens and 20s. Winds will be westerly at 25 to 35 miles per hour with higher gusts. Strong west winds and new snow will continue to build soft surface slabs. These slabs are likely to be easily triggered by humans and could release naturally on steep wind loaded aspects. Slab depths of one to three feet are possible at the higher elevations (9,000 to 10,500 feet) where the general avalanche hazard is expected to be CONSIDERABLE. Pockets of slab up to two feet in depth could be human triggered on steep slopes with fresh deposits of wind-blown snow below an elevation of 9,000 feet where the general avalanche hazard is expected to be MODERATE. Some potential may exist in isolated areas for hard slabs up to four feet deep to occur especially if larger triggers such as snowmachines are involved.
