Regions: Chic-Chocs.

A lot more rain, sometimes turning to heavy snow, is forecast for Friday. This will put considerable pressure on the snowpack, and it would be wise to avoid avalanche terrain until Saturday.

Confidence

Low

Avalanche Summary

Few observations in the field today. Le Couloir reported an avalanche of wet loose snow : https://www.facebook.com/share/r/15tZh46rBH/

If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

Moist snow on the surface, which could form a crust before the snowfall forecast for Friday afternoon. Snow cover in the alpine has probably diminished considerably due to extreme southerly winds, rain and high temperatures.

The middle of the snowpack is well consolidated, resting on a layer of rounding facets. The height of the snowpack currently varies from 100 cm to 200 cm.

Weather Summary

WEATHER FOR THE CRESTS AND SUMMITS OF CHIC-CHOCS

Thursday evening and night: Rainfall 5 to 10 mm. Southeast winds 5 to 15 km/h. Low +1 °C.

Friday: Rain turning to snow in the early afternoon. Risk of freezing rain in the morning. Accumulations of 5 to 7 mm of rain and 10 to 15 cm of snow. Westerly winds of 30 to 50 km/h. Temperatures stable near 0°C during the day, dropping to -15°C overnight on Friday.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy rain.
  • Keep in mind that the high density of wet avalanches can make them destructive.

Avalanche Problems

Loose Wet

The rain is likely to destabilize the light snow that was on the surface before the storm.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2

Wet Slabs

In places where a wind slab problem existed before the storm, rain could percolate to an underlying weak layer and trigger a wet slab. The probability is low, but the danger exists.

Aspects: North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
