Highlights

Another beautiful day to enjoy the mountain.

Don't forget that at this time of year, conditions are dynamic and remember to bring your sunscreen, water, and wax for your skins!

Avalanche problems

  • Cornices

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–1.5

    The spring weather conditions, in particular in the absence of overnight refreeze, contribute to weakening the cornices. Even small, a cornice fall can be destructive with serious consequences. Since they are very unpredictable, it is best to stay away from them at all times.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–1.5

    The heat and the intense solar radiation will promote the triggering of small loose wet snow avalanches, in particular on the steep slopes on solar aspects.

Snowpack Summary

The lack of refreeze in the last few days has greatly affected the snowpack. The much appreciated corn snow is becoming wet snow, saturated in water. The northern aspects should be favoured. The effects of the sun are not felt there, so only the mild temperatures are affecting the snow, thus limiting the consequences. In general, at all altitudes, the melting continues. The northern aspects will once again offer the greatest snow cover.

More and more places are now without snow cover, mainly at and below treeline, where conditions are rather minimal.

The height of the snow cover is about 80 cm at mid-mountain.

Weather Summary

Forecast for the Chic-Chocs ridges and summits.

Synopsis: The high pressure ridge persists and the weather will remain perfect for a great time outside.

Friday evening and night: Partly cloudy. Light winds from the west. Max +0C. Freezing level 1700m.

Sunday: Generally cloudy. Winds from 20 to 30 km/h from the south. Max +6C. For more details, see the Chic-Chocs alpine forecast.

Terrain and Travel Advice

  • Caution around slopes that are exposed to cornices overhead.
  • As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches
