Cold weather is forecast to warm, but is still a concern. Review this blog for strategies for managing the cold.
On Friday, A large (size 2) skier trigger storm slab on a south east aspect at 2200 m was reported north west of Slocan lake. Near white water a naturally triggered size one avalanche was observed at 2250m on a north aspect. On Thursday a report of a remotely triggered size 1 persistent slab avalanche in the Rossland Range was submitted.
In the past week, as much as 70 cm of snow has accumulated in some areas. This new snow has buried a variety of old surfaces, including surface hoar on sheltered, north-facing terrain and a sun crust on south-facing slopes.
The middle of the snowpack contains a series of old melt freeze-crusts.
A thick crust deep in the snowpack largely protects any weak layers further down in the snowpack from being triggered.

Terrain and Travel Advice
- Give the new snow several days to settle and stabilize before pushing into bigger terrain.
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
Recent storm snow requires time to stabilize and bond. Recent moderate to strong winds have redistributed this new snow into lee terrain. In some areas the new snow may be sitting on a weak layer of surface hoar.
