In sintesi

The general avalanche hazard remains MODERATE above an elevation of 9,000 feet and LOW below that elevation. At the higher elevations some potential may remain for humans to trigger deep hard slab avalanches in isolated avalanche paths. New snow lies upon hard snow surfaces and could also be triggered as loose snow sluffs. Avalanches are unlikely below an elevation of 9,000 feet. As the day warms, expect sun balling and very small wet slides involving only the new snow in steep terrain at all elevations.

    Weak snow persists near the base of the snowpack. In isolated areas, dangerous hard slabs with depths to 40 inches could be human triggered on this layer. This basal weakness is limited in distribution and is most likely to be found along the east slope of the Wyoming Range in upper elevations in avalanche paths that face north to southeast. Rapid warming and direct sunlight will increase the sensitivity of these slabs this afternoon.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Another weak disturbance will bring the chance for periods of light snow tonight through Thursday morning. Periods of sun are expected during the afternoon when temperatures in the mountains are to reach the mid-thirties. Southwest winds are to have ten to twenty mile per hour averages.The general avalanche hazard is expected to be Low in the Tetons where a mostly stable snowpack exists. Avalanche activity will be limited to loose snow sluffing or small very soft slabs in steep wind loaded terrain features. In the Togwotee Pass and Southwest Trails areas the hazard will be Moderate. In these areas, in addition to the loose new snow hazard, a slight chance continues for slabs to fail on weak snow deep in the snowpack. This hazard exists only above 9,000 feet in some steep avalanche paths.
