Regions

Chic-Choc Mountains.

Tuesday will be the last fine day to enjoy winter conditions before Wednesday's rain and the refreezing crust that should form on Thursday.

Confidence

Moderate

Avalanche Summary

No new avalanches reported or observed.

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

Snowpack Summary

In the alpine and in areas affected by the wind, you'll find a multitude of old, very hard wind slabs.

These slabs are overlying older/denser snow or a weak layer of facet grains.

Between 5 and 20 cm of cold powdery snow can be found on sheltered slopes. The mid-snowpack is well consolidated, resting on the December 30 combo of facets and crust. Facets and depth hoar are developing at the base of the snowpack.

Weather Summary

Synopsis: Tuesday will be the calm before the storm. According to the weather models, we're expecting close to 30 mm of rain starting on Wednesday, with warm temperatures and strong winds. This will be followed by a drastic drop in temperatures on Thursday, and perhaps a little snow.

Monday evening and night: Cloudy. 5 cm of snow. Wind northwest, 20-30 km/h. Minimum -13C.

Tuesday: Cloudy. Wind south, 30 to 40 km/h. High -3C.

Wednesday: Cloudy. 20 mm rain. Wind south, 40 to 60 km/h. Maximum +5C. Freezing level at 2500m.

Thursday: Cloudy. 10 mm rain followed by 10 cm snow. Wind northwest, 40 to 60 km/h. Cooling temperatures down to -20C.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Avoid rock outcroppings, convexities, and anywhere the snowpack is thin and/or variable.
  • Be cautious of buried obstacles especially below treeline.

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.
