In sintesi

Above 9000 feet, a chance remains to trigger slabs that formed during last weeks storm cycle. In north facing terrain at those elevations, weak snow at the base of the snowpack continues to be a season long concern. Larger triggers such as groups of skiers or snow machines may be required to cause failure of these slab problems. The snowpack is mostly stable below 9000 feet where avalanche activity is unlikely. Evaluate snow and terrain carefully and avoid features of concern today.

    Dense to hard slabs were formed last week during a major storm that brought heavy snowfall and strong southwest winds to the area. Failure on the many density breaks during the storm is no longer expected, however failure does remain possible on the weak snow or hard crust layers buried during the early days of the storm. If triggered these slabs could have depths from one to three feet and are most likely to be found in very steep avalanche paths, particularly near cliff areas.

    The chance remains for backcountry travelers to trigger very large deep slab avalanches on northerly aspects above 9,000 feet. If triggered, these dangerous hard slabs could involve the full depth of the snowpack. These slabs could be triggered by larger loads such as snow machines or groups of people, or step down from the release of a surface slab.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )The storm impacting the area will deliver its strongest precipitation this evening through midnight. The chance of snow will continue throughout the day on Friday with minimal accumulation expected. Three inches could fall at higher elevations tonight with another one to two during the day on Friday. Temperatures are to be cooler with highs in the mid-twenties on summits while valley reach the low to mid thirties. The general avalanche hazard will be Moderate above 9000 feet where some potential remains for backcountry users, particularly larger loads such as snow machines or groups of people, to trigger slabs formed last week with depths of one to four feet. Below 9000 feet the avalanche danger will be Low and avalanche activity will be unlikely. At Togwotee, a chance still continues to trigger slides to the ground in high steep north facing avalanche paths.
