Regions

Chic-Choc Mountains.

With cloudy skies and light winds, conditions will be pleasant in the mountains. Stay alert for small, isolated wind slabs.

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

Wednesday evening and night: Cloudy. Isolated flurries. South wind at 15 km/h. Low of -5°C.

Thursday: Cloudy. Flurries with an accumulation of 2 to 5 cm. North-northeast wind at 10 to 20 km/h. High of -4°C. Freezing level at 500 m.

Friday: Cloudy. Isolated flurries with an accumulation of 5 to 10 cm. Northwest wind at 20 to 45 km/h. High of -3°C.

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.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
