In sintesi

With strong northeasterly winds and new snow expected on Saturday, wind slabs will remain reactive to skiers passing by. Exercise extreme caution when choosing your route, especially in challenging and complex terrain. Excellent snow conditions can be found below the tree line.

    Wind slabs will remain reactive to skiers on Saturday. With moderate to strong winds from the northeast, the expected snowfall (5 to 10 cm) and 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. New wind slabs will also form on southwestern and western slopes.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

On Friday, an avalanche accidentally triggered by users during the ascent was reported in the Grande cuve area of Mont Albert. For more details, see the MIN.

Snowpack Summary

Saturday's new snow and recent snow will be transported to the southeast, south, southwest, and west slopes. It lies on a variety of surfaces: wind-hardened snow, rocky areas, overlapping wind slabs, and sun crusts. Below the tree line, the snow is generally powdery.

A series of wind slabs of different densities, ranging from softer to harder, is found at the top of wind-loaded slopes in alpine terrain and at the tree line.

In the Madeleine Mines sector, as well as in certain areas on Ernest-Laforce and on the coast, a layer of large frosted grains is buried under 20 to 50 cm of wind slabs.

The average thickness of the snowpack 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.
