Points saillants

Windslabs could still be reactive to skiers. With good weather on the way, if you're planning to increase the scope of your objectives, be sure to assess the snow conditions before committing yourself.

    The moderate north-easterly wind continues to create windslabs in the alpine and at treeline. Where snow is still available for transport, we can expect to encounter reactive windslabs in start zones, under convexities and in cross-loading zones. Windslabs rest on facets, making them more sensitive to triggering.

Avalanche Summary

No new avalanche was reported or observed.

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

Snowpack Summary

Windslabs continue to form on south to west-facing slopes, where snow is available for transport. The height of the snowpack is extremely variable in the alpine and at treeline, depending on elevation and slope.

In sheltered areas, 15 to 25 cm of light snow covers a consolidated snow interface which rest over the December 30 combo of facets and crust. Facets are developing at the base of the snowpack.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Be cautious of buried obstacles especially below treeline.
