Regions: Chic-Chocs.

The extent of the wind slab danger will depend on the amount of snow received on Wednesday morning.

The heavier the precipitation, the more crucial it will be to exercise caution in your decisions.

Confidence

Moderate

Avalanche Summary

No new avalanches observed or reported.

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

Snowpack Summary

The west and north-facing slopes of the alpine and tree line are generally bare or covered with a crust. The new snow has been deposited on top of this crust on the lee slopes to the east and south. However, strong winds have introduced significant spatial variability, with snow densities and wind slabs of very diverse characteristics.

Below the tree line, a layer of low-density snow, ranging from 10 to 25 cm, covers the crust, which typically supports the weight of a person.

The snowpack depth varies between 100 cm and 200 cm.

Weather Summary

WEATHER FOR THE CRESTS AND SUMMITS OF CHIC-CHOCS

A little snow accompanies the passage of a low-pressure system over the Chic-Chocs, followed by a high-pressure ridge and rather cold weather on Wednesday.

Tuesday evening and night: Snow, 5 to 10 cm. Southwest winds at 40 to 60 km/h shifting to northwest at 40 to 60 km/h. Rapid cooling to a low of -13 °C.

Wednesday: Alternating sun and clouds. Northwest winds at 30 to 50 km/h. High of -18 °C.

Thursday: Sunny. Light southwest winds. High of -7 °C.

Friday: Alternating sun and clouds. Winds from the west at 30 to 50 km/h. High of +1 °C. Freezing level at 580 m.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Carefully evaluate steep lines for wind slabs.

Avalanche Problems

Wind Slabs

On Tuesday afternoon, isolated wind slabs showed reactivity on Mount Albert. The new snow, blown by southwest and then northwest winds, could form new wind slabs on convex slopes, under ridges, and in laterally loaded areas. These may rest directly on a crust, providing an excellent sliding surface.

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2
