Avalanche Canada
Recent southerly winds have created fresh wind slabs in the alpine. As the temperature gradually warms over the next few days persistent slabs may become more reactive.
Summary
Confidence
Moderate
Avalanche Summary
There has been little avalanche activity reported in the previous few days. If you do observe an avalanche, consider posting a MIN.
Snowpack Summary
Light new snow amounts are beginning to bury a widespread layer of surface hoar crystals, which sit over a crust on solar aspects and low elevations.
A layer of facets, surface hoar and/or a crust buried mid February, are 30 to 50 cm below the snow surface and has been reactive in snowpack tests.
Deeper in the snowpack, a weak layer of facets and a crust from early December can be found. This layer appears to be dormant but is still worth keeping in mind in thin snowpack areas in the alpine.
Weather Summary
Tuesday Night
Mostly clear. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -10 °C.
Wednesday
Mostly cloudy with 1 to 2 cm of snow. 20 to 40 km/h east ridgetop wind. Treeline temperature -7 °C.
Thursday
Cloudy with isolated flurries. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -5 °C.
Friday
Mix of sun and cloud. 10 to 20 km/h southwest wind. Treeline temperature -4 °C.

Terrain and Travel Advice
- Be careful as you transition into wind-affected terrain.
- Be aware of the potential for large avalanches due to buried weak layers.
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
Problems
Wind Slabs
Light new snow and southerly winds are keeping wind slabs reactive in lee terrain.
Aspects: North, North East, East, West, North West.
Elevations: Alpine.
Likelihood
Expected Size
Persistent Slabs
A buried weak layer of facets and/or surface hoar buried mid-February is still capable of producing large avalanches.
Aspects: All aspects.
Elevations: Alpine, Treeline.
