Regions

Chic-Choc Mountains, Chic-Chocs.

The amount of snow expected between now and Monday afternoon remains uncertain. Test the reactivity of the new snow when travelling through terrain.

Confidence

Low

  • Forecast snowfall amounts are uncertain.
  • Uncertainty is due to the track & intensity of the incoming weather system.

Avalanche Summary

We received a report of an avalanche that occurred on Saturday. The group triggered a wind slab up to 1 m thick in the upper part of a northeast-facing couloir in the Mines Madeleine sector. The avalanche reportedly slid down to below treeline, carrying surface snow with it.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

The snow forecasted on Sunday night into Monday (approximately 10 to 15 cm) should be redistributed on south-facing slopes due to strong northwesterly winds. Most slopes have been heavily affected by the winds of the last few days. Snow cover is highly variable, ranging from completely bare areas to heavily loaded areas.

In sheltered areas, there is 30 to 40 cm of snow of varying density on the surface. Facets lie on top of the December 20 melt freeze crust, which is between 30 and 50 cm deep.

The average snowpack depth at mid-mountain ranges from 50 to 110 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

A weather system from Texas will move south of the region on Sunday, bringing snow to the Chic-Chocs, with precipitation intensifying overnight until Monday.

Sunday evening and night: Snow up to 10 cm. Northeast winds, 20 to 40 km/h. Low -10.

Monday: Snow ending in the afternoon. Accumulation of 5 to 10 cm. Winds from the northwest at 40 to 60 km/h. High -10.

Tuesday: Mostly cloudy. Accumulation 1 to 2 cm. Winds from the southwest at 30 to 50 km/h. Low -6.

Wednesday: Intermittent snow. Accumulation 1 to 2 cm. Wind from the southwest, 20 to 40 km/h. Low -1.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Wind slabs are most reactive during their formation.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
