In sintesi

Persistent weak layers are present in the snowpack. At the higher elevations small to large persistent slab avalanches can be triggered by the weight of a single person on avalanche prone slopes. In areas with a deeper snowpack this problem layer is further below the surface, may be harder to trigger, and can produce large avalanches. In areas where the snow is shallower, persistent slabs may be easier to trigger and smaller. Today's warming temperatures and sunshine could increase the sensitivity of these slabs to human triggers. A careful evaluation of the snow structure and terrain is warranted.

    Slab avalanches that could severely injure or kill a person can be human triggered on avalanche prone slopes. These slabs could be one to three feet deep above an elevation of 8,000 feet where the hazard is moderate. These avalanches could be triggered on suspect slopes that have existing tracks. The avalanche hazard is low below that elevation where avalanches are unlikely except on isolated terrain features.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Light snowfall will taper off by midnight. Friday will be dry. Temperatures will start out in the upper single digits and low teens and rise into the upper teens and 20’s. West-northwest winds will be light.Small to very large persistent slab avalanches can be triggered by the weight of a single person on avalanche prone slopes. These slabs could be one to two feet deep in the areas with a shallow snowpack and 2 to 4 feet deep in areas with a deeper snowpack. In the Teton and Greys River areas the general avalanche hazard is expected to be considerable above an elevation of 7,500 feet and moderate below that elevation. In the Togwotee Pass area the hazard is expected to be moderate above an elevation of 8,000 feet and low below that elevation.
