Regions

Chic-Choc Mountains.

Depending on the amount of snow that fell on Tuesday night, the problem of wind slabs could be greater than expected. Evaluate the slopes carefully before setting off.

Confidence

Moderate

Avalanche Summary

No new avalanches reported or observed.

If you are heading into the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

2 to 4 cm of snow covers a new melt-freeze crust. Below this, 15 to 30 cm of snow rest on a thick, solid melt-freeze crust dating back to March 21. The middle of the snowpack consists of an overlay of well-consolidated snow and melt-freeze crust.

At higher altitudes, the eastern and southeastern slopes enjoy better snow cover, while the southern, western and northern slopes are rather bare.

At mid-mountain, snow depth varies between 60 and 180 cm.

Weather Summary

WEATHER FOR THE PEAKS AND SUMMITS OF THE CHIC-CHOCS

A sunny but cold day is forecast for Wednesday, before the arrival of another system on Thursday, bringing significant quantities of snow.

Tuesday evening and night: Snow flurries. Accumulation of 2 to 4 cm of snow. Northwest winds, 60 to 80 km/h. Low -16.

Wednesday: Sunny. Wind northwest, 30 to 50 km/h. High -13.

Thursday: Snow. Accumulation, 5 to 10 cm. Winds south, 40 to 60 km/h. Maximum -8.

Friday: Snow. Accumulation, 5 to 10 cm. Light winds. High 0.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Closely monitor how the new snow is bonding to the crust.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.

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.
