Regions

Chic-Choc Mountains, Chic-Chocs.

The difficulty of moving around on the icy surface is likely to be a greater concern than the danger of avalanches this weekend.

Nevertheless, remain alert to the formation of wind slabs on the crust.

Confidence

Moderate

  • Forecast snowfall amounts are uncertain.

Avalanche Summary

No avalanche activity was observed or reported.

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

Snowpack Summary

The rapid drop in temperatures on Saturday morning will gradually freeze the snowpack over the weekend, leading to the formation of a widespread crust in the mountains.

The light snow forecast will fall on this crust and may have difficulty sticking to it.

The significant thaw has greatly affected the snowpack. Conditions remain typical for the beginning of the season: there are numerous obstacles on the ground.

Weather Summary

Winter is back! A few snow showers and winter temperatures will follow the significant low-pressure system that hit the Chic-Chocs on Friday.

WEATHER FOR THE CHIC-CHOCS RIDGES AND SUMMITS

Friday evening and night: Rain turning to snow, 3 to 5 cm. Wind from the south, becoming south-westerly, 50 to 70 km/h. Temperatures dropping to a low of -10 °C.

Saturday: Light snow showers, 1 to 2 cm. Winds from the west, 60 to 80 km/h, decreasing in the afternoon. High -13 °C.

Sunday: Light snow, 1 to 3 cm. Winds from the southwest, 10 to 20 km/h. High -5 °C.

Terrain and Travel Advice

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.

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.
