Lo esencial

New snowfall and westerly ridgetop winds have created shallow pockets of new soft slab at the mid and upper elevations, which could be triggered by skiers and riders in steep, wind loaded terrain. The possibility persists for backcountry travelers to trigger deeper slabs that formed during the last storm cycle. These slabs could be up to three feet deep. A slight chance remains for these slabs to step down to faceted snow near the base of the snowpack above 7,500 feet. Careful snowpack and terrain evaluation followed by thoughtful decision making will be essential for safe travel in avalanche terrain today.

    Recent snow and strong winds formed soft slabs during the last storm cycle. These slabs lie on a variety of snow surfaces that developed during a dry period between Christmas and January 5th. Slab depths range from one foot at lower elevations to three feet at the higher elevations. These slabs could be triggered by the weight of a single person in very steep terrain that is prone to wind loading.

    Skiers and riders could trigger newly developed wind slabs six to twelve inches deep in steep, wind loaded avalanche terrain above 7,500 feet. Additional accumulation and continued wind will increase the depth and the likelihood of failure as the day progresses.

Avalanche Discussion

Light, scattered snow showers will continue overnight before diminishing during the day on Monday. Cloud cover will also decrease as the day progresses. Overnight lows in the mountains will be near ten degrees before rising into the mid to upper teens during the day. Westerly to northwesterly ridgetop winds will range from 10 to 20 miles per hour.The general avalanche hazard is expected to be Moderate on Monday. Skiers and riders could trigger newly developed wind slabs in steep, wind-loaded terrain. The chance remains to trigger deeper slabs that formed during the last storm cycle. These slides could be up to four feet deep. Faceted snow near the base of the snowpack remains a concern in the Togwotee Pass area. In the Tetons and the Greys River area, a slight chance persists for avalanche activity on these basal facets.
