Avalanche Canada
Small inputs of new snow as we head into the weekend will continue to add incremental load over the weak persistent and deep persistent layers. This will not be enough to trigger a natural cycle but will only add load to a stressed snowpack.
Continue to avoid steep convexities and unsupported features. Be suspicious near open, or connected slopes. Now is not the time to let your guard down.

Snowpack Summary
Previous southwest winds redistributed any loose surface snow onto the already existing persistent slab, particularly in lee features. A layer of Surface Hoar and Facets is down 20-40cm in sheltered areas. Large Facets and Depth Hoar comprise the bottom portion of the snowpack. Snowpack depths vary from 50-100cm depending on location; in the alpine, many exposed features have been stripped to the ground.
Weather Summary
Detailed weather forecasts from Avalanche Canada:
Terrain and Travel Advice
- Make conservative terrain choices and avoid overhead hazard.
- Keep in mind that human triggering potential persists as natural avalanching tapers off.
Problems
Deep Persistent Slabs
The bottom of the snow pack is inherently weak with well developed Facets and Depth Hoar. Avalanches initiating in the upper snowpack are likely to step down to this layer and gain significant mass.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
A varied slab sits over the December 17th Facet-Surface Hoar layer. This problem is most significant in open tree line features and in the alpine where you can expect a stiffer, likely more reactive slab.
Aspects: All aspects.
Elevations: All elevations.
