General Avalanche Advisory
Dangerous avalanche conditions exist at the mid and upper elevations. 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. Numerous human triggered and natural avalanches occurred on Saturday, one of which resulted in a partial burial. 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.
TODAY'S AVALANCHE PROBLEMS
TYPE OF PROBLEM
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.
