Regions

Chic-Choc Mountains, Chic-Chocs.

Enjoy the beautiful day in the mountains on Thursday before the storm (rain) arrives on Friday.

Confidence

Moderate

  • Uncertainty is due to the track & intensity of the incoming weather system.

Avalanche Summary

No avalanche activity was observed or reported.

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

Snowpack Summary

There is considerable spatial variability in the areas affected by wind, ranging from bare surfaces to wind-driven snow accumulations. In areas sheltered from the wind, there is approximately 10 to 20 cm of light snow on the surface.

The snowpack thickness varies between 50 and 100 cm. Accumulation is greater in areas prone to snow loading (gullies, couloirs, depressions).

We are still in early season conditions: there are numerous obstacles on the ground, and they are still very much present!

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND SUMMITS

A significant low-pressure system will pass over the Gaspé Peninsula on Friday, causing temperatures to rise to 10 °C, with extreme southerly winds and heavy rainfall.

Wednesday evening and night: 1 to 3 cm of snow. Northwest wind, 30 to 50 km/h. Low -13.

Thursday: Alternating sun and clouds. West wind, 40 to 60 km/h. High -5.

Friday: Intermittent rain, 6 mm during the day and 15 mm overnight. Winds from the south at 80 to 100 km/h. High +10.

Saturday: Cloudy, 4 to 6 cm. Winds from the west at 60 to 80 km/h. High -10.

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

Terrain and Travel Advice

  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Be cautious of buried obstacles, especially below treeline.
  • Watch for rapidly changing conditions during periods of heavy loading from new snow, wind, or rain.

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.
