Avalanche Forecast
Regions: Chic-Chocs.
Rain could quickly destabilize the snowpack. Use extreme caution if venturing into the mountains.
Confidence
Moderate
Avalanche Summary
No new avalanches observed or reported.
If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).
Snowpack Summary
Surface snow is moist on all slopes and at all altitudes. By the end of Monday, a widespread refreezing crust should have formed in the mountains.
The surface snow, which varies in thickness from 5 to 40 cm depending on location, rests on a refreezing crust formed on March 7th. This crust appears to be thicker in the alpine than below treeline.
In alpine areas and at treeline, there is very little snow on the western and northern slopes. Snow depths vary between 70 cm and 200 cm.
Weather Summary

Terrain and Travel Advice
- A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Keep in mind that the high density of wet avalanches can make them destructive.
Avalanche Problems
Wet Slabs
With high temperatures and precipitation in the form of rain expected on Monday, water could percolate in the upper part of the snowpack and slide over the refreezing crust formed on March 7. This water would carry with it the snow above the crust, which could pose a problem in areas where a recent wind plate was present.
Aspects: North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2
Loose Wet
Although often small, during periods of melting or prolonged precipitation, loose wet avalanches can grow in size and become destructive. Watch this video.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2
