Avalanche Summary
An accident involving snowmobilers occurred on Tuesday, March 26, near La Martre, just outside our forecast area. For more details, please consult the MIN report.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
The top 25 to 30 cm of the snowpack is moist or wet. The rainfall still to come will help to make the upper part of the snowpack isothermal, allowing water to percolate down to the underlying crust.
There is a crust of 4 cm thick down 40 cm from the surface. Beneath this crust, there is 20 cm of dry snow resting on a layer of ice that extends to the base of the snowpack.
Last weekend's wind loaded the south and southeast slopes with snow in the alpine and at treeline.

Terrain and Travel Advice
- Keep in mind that wet avalanches can be destructive due to their high density.
- Avoid avalanche terrain during periods of heavy rain.
Problems
Wet Slabs
Warm temperatures and precipitation in the form of rain could trigger wet slabs in places where a slab (storm or wind) existed. Every day of warm weather increases the risk of avalanches.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Loose Wet
Warm temperatures and rain could produce small avalanches of loose wet snow. The risk is greater on steep slopes. The more water-logged the snow (slush), the greater the avalanche risk.
Aspects: All aspects.
Elevations: All elevations.
