Regions: Chic-Chocs.

The storm have left less snow than expected, which has been moved by northeasterly winds to form wind slabs in the upper lee slopes and cross loaded areas.

Watch out for wind-loaded areas, especially on steep slopes and convex rolls.

Moderate

Avalanche Summary

No new avalanche activity has been observed or reported.

More and more relevant information is shared by users with the Mountain Information Network. Thank you for contributing to the collection of this valuable data! You can also continue to write to us at [email protected].

Snowpack Summary

Following the storm, an additional 10 to 15 cm of snow is added to the 20 to 30 cm of low density snow covering the January 2 crust. This crust supports the weight of a skier or snowboarder.

In areas exposed to the winds, there is a variety of surfaces affected by the wind, ranging from soft slabs to hard slabs, as well as sastrugis or the crust directly on the surface.

In general, the height of the snowpack varies from 50 to 100 cm depending on the area and the elevation.

Weather Summary

Forecast for the Chic-Chocs ridges and summits.

Synopsis: A ridge of high pressure brings sunshine for Sunday while a low pressure system moves up from the south to bring mixed precipitation from Monday.

Saturday evening and night: Clearing, northerly winds 30 to 50 km/h, minimum -17 C, freezing level at valley bottom.

Sunday: Sunny, northeasterly winds 20 to 40 km/h, maximum -7 C, freezing level at valley bottom.

Monday: Periods of snow, 5-10 cm, northeasterly winds 50 to 70 km/h, maximum -5 C, temperature inversion, freezing level at valley bottom.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.

Avalanche Problems

Wind Slabs

Wind slabs have developed with moderate to strong northeast winds over the past 24 hours. They are found at the top of W-SW-S slopes in the alpine and in cross loaded areas at treeline. Our observations of the day show that they react to the passage of a skier, but with a limited propagation.

Aspects: South, South West, West.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5
