In sintesi

Some potential persists for backcountry travelers to trigger surface slabs in very steep, wind-loaded avalanche terrain at the mid and upper elevations. The snowpack is mostly stable at the lower elevations and avalanches are unlikely.

    Snowfall over the weekend was accompanied by southwesterly to westerly ridgetop winds. This scenario was followed by moderate to strong northerly to northeasterly ridgetop winds which redistributed snowfall and stiffened wind slabs. Skiers and riders could trigger these slabs with depths of one to two feet on a variety of aspects above 7,500 feet. The likelihood of triggering these slabs will decrease with a drop in elevation where winds were less of a factor.

Avalanche Discussion

Friday looks to be mostly clear in the morning with increasing afternoon clouds as a weak system approaches. This system is not expected to bring significant snowfall but will break down the inversion conditions. Valley temperatures should be slightly warmer tomorrow morning and mountain temperatures are to reach the upper teens to low twenties. The general avalanche hazard will be moderate above 9000 and low below that elevation. At the higher elevations wind slabs with depths to two feet lie on a variety of aspects. In the Togwotee Pass area weak snow persists near the base of the snowpack on high north facing slopes where deeper failures are possible.
