Weather Forecast
Overnight cooler temperatures are expected for the next several days, which will provide a stabilizing effect to the snowpack surface. No significant precipitation is expected, and sunny conditions will provide strong solar radiation to south and southwest steeper slopes.
Snowpack Summary
Up to 50cm of more settled snow and several different crusts to near treeline elevations provide a lot of support and good travel in the upper snowpack. These firmer upper layers are resting on 50-75cm of weak, poorly bonded faceted snow crystals. Large triggers like small avalanches or cornice drops will easily collapse the upper bridging layers.
Avalanche Summary
No new avalanches were observed or reported today.
Problems
Deep Persistent Slabs
Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
