Regions

Chic-Choc Mountains.

Wind slabs may still be unstable in places. It's crucial to assess and test the slope carefully before setting off.

Confidence

Moderate

Avalanche Summary

A few very small wet loose avalanches were observed on Thursday on southern aspects.

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

Snowpack Summary

A new surface crust has probably developed on sunny slopes due to Thursday's sunshine. In areas sheltered from the wind, there is between 5 and 30 cm of new snow on top of a refreezing crust.

As a general rule, west- and north-facing slopes, both in the alpine and at treeline, are bare or crust-covered. Snowpack thickness varies between 100 cm and 200 cm.

Weather Summary

WEATHER FOR THE CRESTS AND SUMMITS OF CHIC-CHOCS

Thursday evening and night: Partly cloudy. Wind southwest 35 to 60 km/h becoming light. Low -9.

Friday: Becoming cloudy in the morning, followed by a few flurries. Accumulation of 2 to 4 cm. Wind 30 to 50 km/h from the west. High -3. Freezing level at 500 m.

Saturday: Intermittent snow. Snow flurries possible, 4 to 6 cm. Wind southwest, 30 to 50 km/h. High -1. Inversion in the afternoon.

Sunday: Alternating sun and clouds. Wind 40 to 70 km/h from the south. Maximum +8. Freezing level at 3500 m.

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

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.

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.
