GENERAL AVALANCHE ADVISORY

Skiers and riders still have the potential to trigger large to very large persistent deep slab avalanches above 7,500 feet. These slides are more likely to occur in terrain where the faceted layers from December and January reside less than three feet below the snow surface. Backcountry travelers might also be able to trigger an isolated pocket of wind slab up to a foot deep in steep, wind-loaded terrain near high elevation ridgelines. Monitor the weather and be willing to turn around if conditions warrant. Below 7,500 feet, the snowpack is mostly stable and avalanches are unlikely.

DESCRIPTION

The possibility remains for skiers and riders to trigger dangerous persistent deep slab avalanches above 7,500 feet. Large triggers, such as snowmobiles or cornice failures, are more likely to be able to impact the deeply buried weak layers of faceted snow. However, the weight of a single skier might be sufficient to trigger one of these persistent deep slabs if a shallow, weak zone is encountered. These low probability/high consequence slides could range in depth from two to five feet and will carry severe consequences for anyone involved.
