Deep instabilities may persist in some slide paths at the upper elevations. Large human triggered avalanches remain a possibility in isolated areas. Wet slides are possible below an elevation of 8,000 feet where isothermal snow exist on steep snow covered slopes.
In isolated areas at the upper elevations depth hoar persists near the base of the snowpack. Deep hard slabs with depths to 40 inches could be human triggered on this weak persistent layer. This basal weakness is limited in distribution and is most likely to be found along the east slope of the Wyoming Range.
( Discussion is generated from the previous day's afternoon forecast. )Strong winds and areas of snowfall are expected overnight as a storm system passes to our north. Several inches of snowfall are possible before skies begin to clear on Wednesday. Winds will be from the west-southwest at 20 to 30 miles per hour with higher gusts. Temperatures will remain in the 20s at the higher elevations and in the 30s in the valleys.Mostly stable conditions exist with some isolated areas of instability. At the upper elevations recent snow and strong westerly winds will continue to form small pockets of wind slab. Buried weak layers persist in some upper elevation avalanche paths in the Togwotee Pass area and the Wyoming Range. Although the general avalanche hazard is mostly LOW isolated areas of MODERATE hazard persist at the upper elevations.
