Regions

Chic-Choc Mountains, Chic-Chocs.

The wind slabs that formed over the weekend are still present. Approach the upper slopes of the eastern sectors with caution or opt for forested terrain., where the snow remains powdery.

Confidence

High

  • We are confident due to a stable weather pattern.
  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

Small slab avalanches on Mount Lyall were reported on Saturday on the mountain information network (see MIN).

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

Snowpack Summary

In alpine terrain and at treeline, the snowpack is characterized by alternating wind-blown snow and layers of wind slabs. Wind slabs are 20 to 60 cm thick in start zones.

Below 600 m elevation, a brittle melt-freeze crust is present at a depth of approximately 10 to 20 cm.

In general, the first two-thirds of the snowpack are gradually denser. At its base, there is a combination of crusts and facets resting on the ground.

The average height of the snowpack at mid-mountain is approximately 120 cm.

Weather Summary

A high-pressure ridge will bring calm, cold, and generally clear weather on Monday.

Sunday evening and night: Generally cloudy. Northwest winds 20 to 40 km/h. High −23 °C.

Monday: Partly cloudy. East winds 20 km/h. High -13 °C.

Tuesday: Cloudy. Snow 2 cm. Northwest winds 20 km/h with gusts to 40 km/h. High -15°C.

Wednesday: Cloudy. Northwest winds 20 km/h with gusts to 50 km/h. High -17°C.

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.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.

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.
