Avalanche Canada lbaker, Avalanche Canada


New snow and moderate southwest winds will build fresh slabs at higher elevations. Avoid areas that feel stiff or slabby under your skis, they may be more reactive to human triggering.




Avalanche Summary

No new avalanches were reported by 4 pm on Tuesday.

On Monday, a skier accidental size 1 storm slab avalanche was reported on an east aspect at treeline.

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

Snowpack Summary

New snow is accumulating over faceted surfaces in many areas and wind-affected surfaces in open areas at all elevations.

A layer of surface hoar is found down 70 cm in sheltered, north-facing terrain. This layer appears as a sun crust on south-facing slopes. As temperatures slowly warm this layer may become reactive to human triggering. 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

  • Watch for signs of slab formation throughout the day.
  • Be especially cautious as you transition into wind affected terrain.
  • Use appropriate sluff management techniques.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.


Storm Slabs

As storm snow accumulates through the day watch for signs of instability, such as cracking and recent avalanches, increasing. Be especially cautious in leeward terrain where southwest winds may be developing more cohesive slabs.
