Avalanche Canada
Avoid all avalanche terrain.
A deeply buried weak layer may cause large avalanches to run to the valley bottom.

High
Avalanche Summary
On Sunday, numerous small wet loose avalanches occurred during warm temperatures and sunshine. A few of them triggered wind slabs.
Snowpack Summary
Heavy snowfall is expected to drop 20 to 60 cm by the end of the day Wednesday. This snow falls on:
Large surface hoar crystals in sheltered spots at treeline and below.
Likely a crust on solar slopes.
Old wind affected snow.
A layer of surface hoar from early January is buried 20 to 40 cm deep. It's uncertain whether this layer will persist.
100 to 200 cm deep in the snowpack are layers of crust, facets, and possibly surface hoar that were buried in December.
The lower snowpack is generally well-settled and unconcerning.
Weather Summary
Tuesday Night

Terrain and Travel Advice
- Avoid avalanche terrain during periods of heavy snowfall.
- Make conservative terrain choices and avoid overhead hazard.
- As the storm slab problem worsens, the easy solution is to choose more conservative terrain.
Problems
Storm Slabs
Storm slabs are expected to be easy to trigger. If triggered, they may step down to the persistent problem.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
A buried weak layer from early December is expected to produce avalanches under the weight of the new snow.
Aspects: All aspects.
Elevations: Alpine.
