Although avalanche danger has decreased post-storm, take a cautious approach and gather your own snow pack information before committing to exposed terrain.

Confidence

Poor - Due to the number of field observations

Weather Forecast

Temperatures should stay cool through the weekend, with the freezing level dropping to around 500 m. Any remaining snow flurries on Saturday should taper off by Sunday. Winds should be mainly light, possibly picking up again by Monday.

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.

Avalanche Problems

Storm Slabs

Storm slabs and wind slabs may be triggered by the weight of a person or sled. A surface slab may be able to step down and trigger a deeper weak layer, creating a surprisingly large avalanche.

Dodge recently wind loaded features by sticking to ridge tops and ribs.>Avoid convexities or areas with a thin or variable snowpack.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 4
