Lo esencial

Conditions remain highly variable across the forecast area. In some locations, older wind slabs may still react to a skier’s weight, especially in the Mines Madeleine area. Don’t get caught off guard — actively assess slab reactivity and choose your terrain accordingly.

    Across most of the forecast area, wind slabs appear to have stabilized and are no longer reacting to skier traffic.

    However, a problematic weak layer has been observed in the Mines Madeleine area as well as in some coastal locations. In these areas, wind slabs are resting on a layer of very large rimed grains buried 10–50 cm deep. Recent tests show that these wind slabs are easy to trigger while skiing on these aspects. This problem is most commonly found below ridgelines, in snow-loaded features, and on southeast through northwest aspects.

Confidence

Moderate

  • We are uncertain due to a highly variable snowpack.
  • 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

In alpine terrain and at treeline, snow coverage is highly variable: north and west aspects are often scoured, while other aspects alternate between firm snow and stacked wind slabs of varying densities.

Below treeline, 10–20 cm of powder snow overlies a snowpack that gradually becomes denser.

A series of sun crusts is present on steep south-facing slopes. In most areas, these crusts are friable and do not significantly impact travel.

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

The average snowpack depth at mid-elevation is approximately 110 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.

Monday evening and overnight: Generally cloudy. Southwest winds at 10–20 km/h. Low of -8°C.

Tuesday: Cloudy. Snow beginning in the afternoon. Accumulation of 5–10 cm. Southwest winds at 20–40 km/h. High of -5°C.

Wednesday: Snow. Accumulation of 5–10 cm. Northeast winds at 10–20 km/h. High of -6°C.

Thursday: Cloudy. Accumulation of 2–4 cm. Northwest winds at 30–50 km/h. High of -8°C.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Now is a good time for backcountry travel.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
