Summary
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.
Confidence
Problems
Deep Persistent Slabs
Cornice failures or skier travel in shallow snowpack areas are likely ways to trigger this deep weakness in the snowpack.
Avoid exposure to overhead avalanche terrain, large avalanches may reach the end of run out zones.Avoid shallow snowpack areas where triggering is more likely.
Aspects: All aspects.
