Avalanche Summary

No new reports of avalanches. Please let us know what you're seeing out there. Submit your observations to the Mountain Information Network.

Snowpack Summary

Conditions in the Coquihalla area are quite different to the Duffey region. Reports from the Coquihalla suggest there's less than 1 m of snow in most avalanche areas with a relatively simple, recently rain-soaked, snowpack. Around the Duffey, we have limited observations, but it's expected that fresh storm and wind slabs exist and that these may be overloading snowpack weaknesses formed in November.

Problems

Storm Slabs

Storm slabs and wind slabs may be triggered naturally or by the weight of a person. A surface slab may be able to step down and trigger a deeper weak layer.

Choose well supported terrain without convexities.>Use ridges or ribs to avoid wind loaded and cross loaded slopes.>

Aspects: All aspects.

Elevations: Alpine, Treeline.
