Avalanche problem #1 :
For Wednesday, storm slabs are possible in the alpine and at treeline. Recently fallen snow (10-15 cm) in addition to snowfalls from Monday (15-20 cm) have created instabilities such as wind slabs in the alpine and loose dry snow at treeline on steep slopes. Although expected avalanches remain small, they can transport you toward obstacles such as rocks, trees and stumps lower down the slope.
Despite the latest snowfalls (25-35cm), the snowpack conditions are still marginal. Winds, with variable intensity and direction with the last 72h, have swept alpine slopes to the rock (S-SW-W) and loaded significantly (up to 100 cm) other slopes (N-NE-E). At treeline, 15-20 cm of very light snow can be found at the surface, which sits on a layer of denser and firmer snow, as well as a crust near the ground. Snowpack height varies between 70 and 140 cm. Below treeline, the snow depth varies from 30 to 60 cm, barely covering terrain roughness.
A mix of sun and clouds are expected Wednesday with moderate North-West winds (30 km/h) near the summits. Thursday should be a sunny day, with light South-West winds (10km/h). Max daily temperatures will stay around -12C in the mountain and -6C in the valley. Nights will be below normal (-20C).
At the beginning of the season, our observations in the mountains are limited. We are therefore particularly interested in your information which you can send us by email at firstname.lastname@example.org or via Avalanche Canada’s Mountain Information Network (MIN).

This avalanche bulletin is prepared with the most recent weather, snowpack and avalanche activity data available for the Chic-Chocs. It is strictly information that can be used as a part of a decision making process and is not intended to be a replacement for knowledge about avalanche safety including and not limited to safe travel practices and the use of backcountry rescue equipment such as beacon, shovel and probe.
