Avalanche Forecast

Moderate

On Thursday there was a report of a remotely triggered (from a distance)size 1 persistent slab avalanche in the Rossland Range. On Wednesday in the Bonnington range there was a report of a naturally triggered size 3 avalanche on an east aspect in the alpine. This was suspected to have run on a layer of surface hoar buried in early January.

If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).

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.

• 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.
