Regions: Chic-Chocs.

The weather conditions - new snow, winds and rising temperatures - are combined to reduce the stability of the snowpack. It seems that winter conditions are still present in alpine terrain. Evaluate the slopes carefully before setting off.

Confidence

Moderate

Avalanche Summary

No new avalanches observed or reported.

If you're out and about in the backcountry, please share your observations on the RIM ( Réseau d'Information en Montagne ).

Snowpack Summary

Up to 40 cm of fresh snow (moist below 600 m) lies on a widespread refreezing crust. The upper part of the snowpack, up to 90 cm deep, is moist. The middle of the snowpack consists of alternating well-consolidated snow and refreezing crusts.

There is considerable spatial variability in the alpine zone and at the treeline (presence of rocks, ice, blown snow). At mid-mountain, snowpack thickness varies from 80 to 200 cm.

Weather Summary

WEATHER FOR CHIC-CHOCS PEAKS AND SUMMITS

A sunny day in the mountains on Friday before the arrival of another low-pressure system.

Thursday evening and night: Cloudy. Northwest winds, 45 to 60 km/h. Low -6. Freezing level to valley bottom.

Friday: Clearing in the morning. Wind northwest, 20 to 40 km/h. Maximum +2. Freezing level at 900m.

Saturday: Rain, 5 to 10 mm. Wind southwest, 20 to 40 km/h. High +5. Freezing level at 2800m.

Sunday: Snow. Accumulation 25 to 35 cm. Wind northwest, 60 to 90 km/h. Maximum 0. Freezing level at 600m.

For more details, consult the Chic-Chocs alpine weather forecast.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Carefully evaluate steep lines for wind slabs.

Avalanche Problems

Wind Slabs

About 40 cm of snow have accumulated since Tuesday evening, and the prevailing winds are favouring the formation of wind slabs, whose reactivity remains difficult to predict.

Aspects: East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Loose Wet

Recently fallen snow lies on a crust. At lower altitudes, it is moist and reacts in places to skiers.

Aspects: All aspects.

Elevations: Below Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
