Lo esencial

We are uncertain about how much snow we will receive and how strong the winds will be by Wednesday evening. Wind slabs of varying size could develop. Travel cautiously and carefully assess the stability of the new snow before committing to your descent.

    New wind slabs may form throughout the day on Wednesday, depending on wind strength. These wind slabs are likely to be particularly reactive to skier triggering, as they will rest on sun crusts or hard, wind-hardened surfaces, providing an excellent sliding surface. Depending on the amount of snowfall received, slab thickness could range from 10 to 50 cm.

    A problematic layer has been observed in the Mines Madeleine sector as well as in some coastal areas. In these locations, wind slabs sit on a layer of very large rimed grains buried 10 to 50 cm below the surface. Recent tests indicate that these slabs are easy to trigger by skiing on these aspects. This issue is primarily found below ridgelines and in areas of wind-loaded snow. The weak layer is mainly present on southeast through northwest aspects.

    Small loose snow avalanches may occur on steep slopes and could catch skiers off guard. Pay attention to this issue during your descents to avoid being pushed into terrain you don’t want to be in. The significance of this problem will depend on how much new snow falls.

  • We are uncertain about forecast precipitation amounts.

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 could receive 10–15 cm of new snow by Wednesday evening. This snow will fall onto a variety of surfaces: wind-hardened snow, rocky surfaces, old wind slabs, sun crust, and below treeline, onto light, unconsolidated snow.

In the Mines Madeleine area, a layer of large facets is buried beneath 30–50 cm of wind slab, producing very easy results in recent stability tests on southeast through northwest aspects.

The average snowpack depth at mid-mountain is approximately 120 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS
A low-pressure system will move across the Gaspé Peninsula over the next few days, bringing several centimetres of fresh snow.

Tuesday night: Snow. Accumulation of 5–10 cm. Southwest winds 10–20 km/h. Low −7 °C.

Wednesday: Snow. Accumulation of 4–6 cm. North winds 10–20 km/h. High −5 °C.

Thursday: A mix of sun and cloud. Accumulation of 2–4 cm. Northwest winds 15–30 km/h. High −8 °C.

Friday: Sunny. Northwest winds 15–30 km/h. High −19 °C.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Approach lee and cross-loaded slopes with caution.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Use appropriate sluff management techniques.
