Regions

Chic-Choc Mountains, Chic-Chocs.

Newly formed wind slabs rest on a crust that provides an excellent sliding surface for avalanches. Carefully assess the presence of these slabs and their adhesion to the crust before venturing onto a steep slope, in alpine terrain or at the tree line.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanches reported or observed.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

The wind caused significant spatial variability in alpine and at the tree line, with conditions ranging from icy surfaces to powder snow, including packed snow and soft wind slabs.

Between 10 and 20 cm of light, low density snow covers a widespread crust. This crust is very hard in the alpine. Below the tree line, it is sometimes more brittle and unable to support a skier’s weight. Under the crust, the snowpack is well-consolidated.

At mid-mountain, the average depth of the snowpack is around 140 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

Cloudy conditions and milder temperatures as a low-pressure system approaches.

Saturday evening and night: Cloudy. South-westerly wind 20–40 km/h. High -16°C.

Sunday: Cloudy, with a few snow showers, 2 to 4 cm. South-westerly wind 20 to 40 km/h. Maximum -10°C.

Monday: Snow 5 to 10 cm, slight chance of rain. Southerly wind 10 to 20 km/h. Maximum -1°C. Freezing level at 550m.

Tuesday: Sunny. North-westerly wind 20 to 40 km/h. Maximum -4°C.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Carefully evaluate steep lines for wind slabs.
  • Expect slab conditions to change drastically as you move into wind-exposed terrain.
  • 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.
