The avalanche hazard will remain elevated over the next couple days as strong winds and small inputs of new snow continue.
Summary
Confidence
Moderate
Avalanche Summary
A number of large avalanches up to size 3 have been observed and reported over the week. The snowpack is very sensitive to small inputs of new snow, loading, and changes in temperature. These avalanches are mostly from the alpine but are running through all elevation bands.
Don't forget to post avalanche observations to the MIN.
Snowpack Summary
Moderate to strong SW winds continue to redistribute snow at treeline and above. Ridge lines are scoured and recent natural activity suggests loading is happening lower in the start zones. Visible wind effect throughout the alpine.
The upper snowpack consists of 30-50 cm of settled snow or wind slab sitting on top of a generally weak mid and lower snowpack. Facets and depth hoar linger at the base of the snowpack with the height of snow varying from 60 to 160cm.
Weather Summary
Light snow and continuing moderate to strong winds are forecast for Friday.

Terrain and Travel Advice
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
Problems
Wind Slabs
Moderate to strong winds from the SW with some new snow continue to build wind slabs in open areas.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Deep Persistent Slabs
The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Natural avalanches continue to step down to this layer resulting in large avalanches.
Aspects: All aspects.
Elevations: All elevations.
