In sintesi

The Cow of the Woods slidepath in the Hoback Canyon released naturally last night and deposited 10 to 15 feet of snow onto the road. Two avalanche problems confront backcountry travelers today. Skiers and riders could easily trigger newly developed wind slabs on a variety of aspects. These slides could step down to persistent weak layers deep within the snowpack. With new snow in the forecast, along with ample snow available for transport and continued strong winds, natural activity will be possible for both of these avalanche problems. Conservative terrain choices will be essential for safe travel at the lower and mid elevations, and TRAVEL IN AVALANCHE TERRAIN IS NOT RECOMMENDED AT THE UPPER ELEVATIONS.

    Around a foot of new snow, which contains close to an inch and a half of water, has combined with strong westerly ridgetop winds to create dense winds slabs one to two feet in depth in leeward terrain. These slabs have formed on good sliding surfaces which include surface hoar, sun crusts and near surface facets. Backcountry travelers could easily trigger these slides on a variety of aspects, and natural releases are possible.

    Yesterday's snowfall added another load to persistent week layers deep within the snowpack. Backcountry travelers could trigger these slides to depths of four to six feet, and natural activity is also possible.

Avalanche Discussion

Periods of snow are expected through Friday as a cold front brings cooler temperatures to the area. The most significant snowfall will occur Thursday evening and could bring another two to four inches to the area. Mountain temperatures are to rise from the single digits in the morning to the teens in the afternoon. Winds are to be from the west with five to fifteen mile per hour averages.The general avalanche hazard will be Considerable in all areas. Recently formed slabs could be triggered with depths to two feet that lie upon slick sliding surfaces. Deeper avalanches can also be triggered on persistent weaknesses within the snowpack. These slides could fail to the ground and are most likely to occur in the Togwotee Pass and Southwest Trails areas where weak snow is more prevalent.
