In sintesi

The general avalanche hazard is HIGH. 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. TRAVEL IN AVALANCHE TERRAIN IS NOT RECOMMENDED AT THE UPPER ELEVATIONS.

    Around 15 inches new snow, which contains close to two inches of water, has combined with strong westerly ridgetop winds to create dense winds slabs up to 30 inches 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.

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

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Snowfall rates exceeding an inch per hour are expected to continue through this evening. After a brief letup Thursday morning, another round of moisture may impact the region through the rest of the day. Strong westerly ridgetop winds will range from 25 to 35 miles per hour. Temperatures will decrease overnight with mountain lows in the mid to upper teens. These temperatures are not expected to rise significantly during the day.The general avalanche hazard is expected to be HIGH on Thursday. Backcountry travelers are very likely to trigger newly developed, dense wind slabs one to three feet in depth in leeward starting zones. Below the new slabs, the snowpack structure is poor and the additional load to the preexisting weak layers will increase the likelihood of triggering slides deep within the snowpack. Natural activity for both the new wind slabs and the deep persistent slabs is likely and TRAVEL IN AVALANCHE TERRAIN IS NOT RECOMMENDED.
