Conditions are variable across the region. If you are heading to the Duffey Lake area, check the Sea-to-Sky and Whistler/Blackcomb bulletins too.
Confidence
Poor - Due to the number of field observations
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.
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
