Regions

South Coast.

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.

Avalanche Summary

No new reports of avalanches. Please let us know what you're seeing out there. Submit your observations by clicking on the "Avalanche Information " tab at the top of the page.

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 Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
