    Tuesday morning's natural avalanche at Mont-Albert confirms the reactivity of the wind slabs. It will be possible for users to trigger wind slabs over the next few days. Caution is advised, especially in the alpine.

Avalanche Summary

A natural avalanche of size 2.5 was reported to us. It occurred early in on Tuesday morning in the Mélèze, on a southern slope.

If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

On Tuesday, the snow became moist up to 700 m of elevation. We can expect a refreezing crust on the surface by Tuesday evening. In the alpine and at treeline, there are a variety of wind-affected surfaces (rocks, hard-packed snow, snow accumulation). At all elevations, 40 to 60 cm of rather light snow resting on a well-consolidated snowpack. Significant presence of facets at the base of the snowpack (up to 60 cm), especially where the snowpack is thinner. Snowpack height varies between 120 and 220 cm.

  • Approach lee and cross-loaded slopes with caution.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
