Tetons

At the upper elevation unstable slabs up to two feet in depth persist on shaded aspects. These slabs could be triggered by the weight of a person in very steep active avalanche paths. Avalanches are unlikely at the mid and lower elevations.

Snowfall will develop, increase overnight and continue through Friday. Strong southwest to west winds will accompany the snowfall and create areas of blowing snow. Accumulations of six to 12 inches are possible in the mountains by late afternoon/early evening. Temperatures will decrease as the storm progresses and end up in the single digits by Saturday morning. The general avalanche hazard is expected to MODERATE at the upper elevations (9,000 to 10,500 feet) and will increase as the day progress. Pockets of new soft slab will form on leeward aspects and may build to depths of 12 to 18 inches by the end of the day. Older slabs up to two feet in depth persist in isolated areas. Humans who venture into steep avalanche starting zones could trigger these slabs. The general avalanche hazard at the mid and lower elevations is expected to be LOW. Isolated pockets of new soft slab up to a foot deep will form on leeward aspects and could be human triggered in steep avalanche starting zones.
