Avalanche Forecast
Regions: Chic-Chocs.
Depending on the system's arrival time on Tuesday, new reactive wind slabs could develop throughout the day.
However, you can still find isolated wind slabs even before the new snow comes in, keep an eye out.
Confidence
Low
Avalanche Summary
Two size 1.5 avalanches were accidentally triggered at the Mur des Patrouilleurs on eastern aspects.
If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).
Snowpack Summary
Little change since Sunday. In wind-exposed areas, northwest to southwest aspects are scoured down to the crust, while the northeast to south aspects show little accumulation (except for the start zones and cross loaded features). Below treeline, 5 to 25 cm of low-density snow overlie the crust, which generally supports the weight of a user.
The snowpack is wet under this crust. It rests on a layer of facets that tends to round out. The height of the snowpack varies between 100 cm and 200 cm.

Terrain and Travel Advice
- Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
- Wind slabs are isolated, but may remain reactive.
Avalanche Problems
Wind Slabs
Although leeward aspects show few slab characteristics, wind slabs do exist in isolated areas. They sit above the crust, which increases their reactivity. Two avalanches were triggered on a cross loaded feature on Sunday.
Aspects: North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
