Regions

Chic-Choc Mountains.

Even though the new wind slabs are isolated, they rest on a crust that provides an excellent sliding layer, and is making mountain travel difficult.

Confidence

Moderate

Avalanche Summary

A natural avalanche estimated to be size 1.5 was observed in the Bol de Toilette, near the Grande-Cuve. It was 24 to 48 hours old. It is a wind slab avalanche that slid on the March 21 crust.

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

Snowpack Summary

Tuesday morning, in areas sheltered from the wind, we could find 5 to 10 cm of new snow that are covering a very firm crust formed on March 21st.

In the alpine and at the tree line, there is little snow on all slopes, except on the east and southeast-facing slopes. There are pockets of accumulation that can reach up to 25 cm on the crust in areas of maximum loading.

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

Weather Summary

WEATHER FOR THE PEAKS AND SUMMITS OF THE CHIC-CHOCS

A depression coming from the Great Lakes is bringing some snow by tomorrow.

Monday evening and night: Snow 5 to 10 cm. South wind at 20 to 40 km/h. Minimum -9.

Tuesday: Cloudy. Snow showers, accumulation of 2 to 4 cm. Southwest wind at 10 to 20 km/h. Maximum -1. Freezing level at 480 m.

Wednesday: Cloudy. South wind at 10 to 20 km/h. Maximum 0. Freezing level at 560 m.

Thursday: Cloudy. Light northwest wind. Maximum -2. Freezing level at 375 m.

For more details, see the Chic-Chocs alpine weather forecast.

Terrain and Travel Advice

  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.

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.
