Regions

Chic-Choc Mountains.

There is some uncertainty as to the type of the expected precipitation. Remember to adjust your itinerary to the changing conditions as the day progresses.

Avalanche Summary

No new avalanche was reported or observed.

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

Snowpack Summary

Surface hoar was observed at all elevations and aspects, except for solar slopes. In the alpine and at treeline, this layer rests on a compacted, wind-affected surface. Below treeline, the first couple centimetres were wet on Friday, and will certainly show a crust on Saturday morning.

The core of the snowpack is well consolidated, and resting on the December 30 combo of facetted grains and crust. Facetted grains and depth hoar are developing at the base of the snowpack.

Weather Summary

Synopsis : A low-pressure system from the Great Lakes will bring mild temperatures and precipitation. Their type and total amounts are uncertain, however.

Friday evening and night : Generally cloudy. Trace of snow or sleet. Southwest winds from 30 to 40 km/h. Minimum -2C. Freezing level at 750m.

Saturday : Cloudy. 2 to 5 cm of snow or light rain. Southwest winds from 45 to 55 km/h. Maximum 0C. Freezing level at 750m.

Sunday: Cloudy. 1 to 4 cm of snow. Northwest winds from 40 to 50 km/h. Maximum -7C.

Monday: Cloudy. Trace of snow. Northwest winds around 40 km/h. Maximum -10C.

Terrain and Travel Advice

  • Adjust your travel plans accordingly to the changing conditions of elevation and time of day.
  • Although their spatial distribution is isolated, wind slabs are reactive.
  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.

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.
