Points saillants

Fair weather and light winds on Sunday, but remain alert for signs of instability, especially in the SE, S, and SW slope loading areas. Excellent conditions persist below the tree line.

    Wind slabs will remain reactive to skiers on Saturday. With moderate to strong north winds overnight from Saturday to Sunday, the snow available for transport will gradually thicken these slabs. They are particularly sensitive because they rest on sun crusts or hardened snow, providing a good sliding surface. Their thickness generally varies from 10 to 50 cm, but could be greater depending on the orientation.

Confidence

Moderate

  • We are uncertain due to the variability of wind effect on the snowpack.
  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

On Friday, a slab avalanche accidentally triggered by users during the ascent was reported in the Grande Cuve sector of Mont Albert. For more details, see the MIN

Also on Friday, another slab avalanche accidentally triggered by a skier was reported in Rock'n'roll, in the Mur des Patrouilleurs sector of Mont Albert. For more details, here is the MIN.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

New snow and wind-blown snow have formed wind slabs measuring 10 to 50 cm thick, mainly in alpine terrain and at the tree line, on east, south, and west-facing slopes. These slabs lie on various surfaces, including old wind slabs and refreeze crusts, creating good sliding surfaces in places. Several north and west-facing slopes are bare.

A superimposition of wind slabs of varying densities is present at the top of wind-loaded slopes in alpine areas and at the tree line.

Below the tree line, there is generally 15 to 25 cm of light snow resting on a gradually denser layer.

In the Mines Madeleine sector, as well as locally on Ernest-Laforce and on some east-west slopes, a layer of large, fragile grains is buried under 20 to 50 cm of wind slabs.

The average snowpack depth at mid-mountain is approximately 120 cm.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Recent strong wind means wind slabs may be found farther downslope than expected.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
