    Wind slabs may be found behind terrain breaks like ridges and ribs. A slab could fail on a deeply buried weakness, creating a surprisingly large avalanche.

Weather Forecast

Mainly clear cool weather. Freezing levels are near 700m. Light to moderate SE winds.

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. There's a small amount of recent storm snow over a relatively simple, recently rain-soaked snowpack. Around the Duffey, we have limited observations, but it's expected that wind slabs exist and that these may be overloading snowpack weaknesses formed in November (avalanches have been failing on these layers in the Whistler area). Below treeline the snowpack is likely be thin and have a sporty surface crust.
