Regions

Chic-Choc Mountains.

In most parts of the forecast area, the height of the snowpack makes it impossible to practice alpine sports safely. Natural obstacles are very (too) close to the surface. Let's be patient and rediscover other means of locomotion to get around the mountains.

Confidence

Moderate

Avalanche Summary

Early season, observations are limited. Thanks for sharing your observation through the Mountain Information Network if you head out.

No new avalanches have been observed or reported. Please share your observations at [email protected] or via the Mountain Information Network.

Snowpack Summary

Between 5 and 20 cm of new snow lies on top of the New Year's crust (the crusty surface left by December's rain). There seems to be more new snow in the south of the forecast area and at higher altitudes. Snow cover remains minimal, however, and in several places the snowpack is below the critical threshold for producing avalanches. The height of the snow cover varies between 5 and 50 cm.

Weather Summary

Synopsis: The Gaspé Peninsula lies between two low-pressure systems, bringing winds from the west. Since the river is not yet frozen, wind circulation will generate light precipitation during the week. A high-pressure system should hit us on Friday.

Tuesday evening and night: Mostly cloudy. Wind 30 to 40 km/h from the west. Minimum -10C.

Wednesday: Cloudy. 2 to 4 cm of snow. Wind 15 to 30 km/h from the southwest. High -6C. Low -11.

Thursday: Cloudy. 3 to 5 cm of snow. Wind 10 to 20 km/h from the south. High -5C.

Friday: Alternating sun and clouds. 1 to 2 cm of snow. Wind 40 to 50 km/h. Maximum -15.

Terrain and Travel Advice

  • Wind slabs may be poorly bonded to the underlying crust.
  • Wind slabs are most reactive during their formation.
  • Expect shallow snow cover that barely covers ground roughness.

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.
