Snowpack Summary
Conditions in the Coquihalla area are quite different to the Duffey/Hurley regions. Reports from the Coquihalla suggest there's less than 1 m of snow in most avalanche areas. On the surface, fairly widespread surface hoar development has been reported. Below this, a small amount of recent storm snow overlies a thick rain crust. In the north, we have very limited observations. That said, I expect a deeper, more complex snowpack where well settled storm snow overlies a mix of crusts and facets which formed in November.
Problems
Deep Persistent Slabs
Persistent weak crystals which formed in November are potentially destructive, and are a bigger issue in the north of the region. Use extra caution in steep, unsupported alpine terrain.
Be aware of thin areas that may propogate to deeper instabilites.>Avoid convexities or areas with a thin or variable snowpack.>
