Avalanche Summary

A wind slab avalanche (size 1) was accidentally triggered by a skier, observed on a northeast facing aspect of Mines Madeleine. It slid on the March 21 crust over a short distance (>50 m).

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

Snowpack Summary

On leeward slopes, 10 to 15 cm of recent snow sits atop a solid melt-freeze crust formed on March 21st, this one generally adheres well to the crust.

In the alpine and at treeline, this new snow overlies various surfaces such as a crust, wind-affected pockets, or bare ground. In areas of maximum loading on lee slopes, isolated spots can be found where accumulations may reach up to 20 cm.

At mid-mountain, the snowpack height ranges from 60 to 150 cm.

Weather Summary

WEATHER FOR THE PEAKS AND SUMMITS OF THE CHIC-CHOCS

Terrain and Travel Advice

  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
  • Carefully evaluate steep lines for wind slabs.
  • Closely monitor how the new snow is bonding to the crust.

Avalanche Problems

Wind Slabs

Wind slabs exist in isolated terrain features such as cross-loaded areas and below convex rolls. These sit on a thick crust, offering a good bed surface for avalanches.

Aspects: North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
