In sintesi

Dangerous avalanche conditions exist above 8,500 feet. Up there, skiers and riders choosing to venture into steep terrain are likely to trigger large to very large persistent slab avalanches. As the day progresses, the likelihood of triggering these slabs will be on the increase. Yesterday, snowmobilers triggered slides up to 30 inches deep on road cuts. Excellent terrain evaluation skills and conservative choices will be essential for safe travel in avalanche terrain. Monitor wind loading and new snowfall throughout the day and be willing to alter your travel plans if conditions warrant.

    Persistent weak layers, which include faceted snow near the base of the snowpack and buried surface hoar, exist in terrain that held snow prior to Sunday November 24th. This terrain generally includes all aspects above 9,000 feet and northerly slopes down to 8,000 feet. Skiers and riders venturing into these areas are likely to trigger slab avalanches up to three feet deep, and natural activity will be possible. New snowfall, snow available for transport and strong winds will exacerbate this hazard throughout the day. Knowledge of the extent and distribution of the faceted weak layers of concern will be essential for accurate terrain evaluation.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Southwesterly flow aloft will start to bring another round of snowfall overnight and through the day on Monday. Overnight lows in the mountains will be in the mid-teens before rising into the mid-20s during the day. Southerly to southwesterly ridgetop winds will range from 20 to 30 miles per hour.The general avalanche hazard is expected to remain Considerable on Monday, and conditions will continue to be dangerous on steep slopes that held snow prior to last Sunday. This terrain generally includes all aspects above 9,000 feet and northerly slopes down to 8,000 feet. Skiers and riders venturing into these areas are likely to trigger large to very large slab avalanches and natural activity will be possible. New snowfall, snow available for transport and strong winds will exacerbate this hazard.
