Regions

Chic-Choc Mountains.

New wind slabs are forming. An incident could quickly be aggravated by the weather conditions.

Confidence

Moderate

Avalanche Summary

No new avalanches reported or observed

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

Snowpack Summary

We have received between 10 cm and 30 cm of new snow since Monday morning. The new snow rests on old, wind-affected snow surfaces in the alpine region and at treeline. The cold weather of recent days has created sporadic layers of facets within the snowpack. These layers produced results in our tests. Prominent peaks and reliefs are blown by the wind, but depressions and departure zones have higher snowfall amounts. Snow depth at mid-mountain varies between 90 and 150 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND SUMMITS

A low-pressure system will approach the region this evening and cross it on Wednesday. A small high-pressure system will then pass over the Chic-Chocs on Thursday, giving very cold temperatures and clear weather.

Tuesday evening and night: Partly cloudy. Westerly winds, 20 to 40 km/h. Minimum -23C.

Wednesday: Alternating sun and cloud. Winds southwest, 10 to 20 km/h. High -16C.

Thursday: Sunny. Trace of snow. Wind northwest, 30 to 50 km/h. Maximum -23C.

Friday: Alternating sun and clouds. Trace of snow. Southerly winds, 10 to 30 km/h. Maximum -15C.

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

Terrain and Travel Advice

  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.

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.
