In the alpine, on Monday afternoon, we will find beautiful conditions of corn snow under a radiant sun.
Although the avalanche danger is much lower in the spring, we still have to be careful not to be caught by small wet snow avalanches, which can lead us to obstacles below, or by cornice falls.

Snowpack Summary
In the alpine, a cycle of overnight freezing and daytime thawing is taking shape for the next few days, bringing the much appreciated corn snow conditions under the strong afternoon sun. At the base of the mountains, in the absence of an overnight refreeze, the heat and intense solar radiation will continue to rapidly transform the snow to fill it with water and continue the accelerated melting of the snowpack. More and more areas are now without snow cover, mainly at and below the treeline where conditions are quite minimal.Snowpack heights range from 0 cm (valley) to 95 cm (mid-mountain).
Weather Summary
Forecast for the Chic-Chocs ridges and summits.
Synopsis: A ridge of high pressure over the area will keep the weather clear for the next few days.Sunday evening and night: A few clouds, no precipitation, winds southeast 20 to 30 km/h, minimum -4 C, freezing level at 500 m.Monday: Sunny, no precipitation, winds southeast 15 to 30 km/h, maximum +6 C, freezing level at 2400 m.Tuesday: Sunny, no precipitation, winds southeast 15 to 30 km/h, maximum +6 C, freezing level at 2000 m.Wednesday: Cloudy, light southeast winds, maximum +4 C, freezing level at 1400 m. 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
Problems
Cornices
The spring weather conditions, in particular in the absence of overnight refreezing, 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.
Aspects: All aspects.
Elevations: Alpine.

Expected Size
Loose Wet
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.
