Snowpack Summary
At treeline, the snowpack sits at about 260cm.In the upper snowpack, weaknesses within and under last week's 80cm of storm snow will need some time to settle and fully strengthen.Persistent weaknesses remain a concern in the many parts of the region. In the mid-pack, facets with an associated crust (resulting from the early December dry spell) at treeline and alpine areas are probably down well over a metre in most places. This layer still seems to be reactive, particularly in shallow areas or terrain with variable snow depths (cross-loaded features, moraines). In the lower snowpack, basal facets from early november should also be on your radar. They may just be waiting for the right trigger (current heavy storm snow loading, cornice fall, step-down avalanches). Any activity on either of these persistent weaknesses would be highly destructive in nature.Expect further storm slab/wind slab development with forecast weather.
