Regions

Chic-Choc Mountains.

Conditions are slowly improving in the mountains, and small isolated wind slabs are developing on the upper alpine slopes. They should be to watch, because even small ones can have serious consequences due to the still minimal snowpack and the many obstacles at the surface or barely covered.

Confidence

Moderate

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

About 10 to 15 cm of new snow was added over the weekend, for a total of 15 to 25 cm of fresh snow that covers the December melt-freeze crust or directly the ground. In the valley, the thickness of the snowpack barely exceeds 15 to 20 cm, while it varies between 50 and 60 cm at mid-mountain. Consequently, conditions remain minimal with rocks, trees and stumps on the surface or barely covered.

Weather Summary

An extended northerly flow is likely to generate persistent snow until Thursday.

Monday night: Snow, 5 to 10 cm, northwesterly winds 20-30 km/h, temperature -5 C, freezing level at valley bottom.

Tuesday: Periods of snow, 2 to 4 cm, northwesterly winds 20-40 km/h, temperature -3 C, freezing level at 150 m.

Wednesday: Snow, 10-15 cm, northerly winds 10-20 km/h, temperature -2 C, freezing level at 250 m.

Thursday: Snow, 10-15 cm, northerly winds 10-20 km/h, temperature around 0 C, freezing level at 500 m.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • 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.
