Test the reactivity of the new snow as you move through the mountains.
The new snow will be accompanied by winds that will promote snow transport. Our uncertainty concerns the underlying bed surface, since several north-facing slopes were bare of snow before the storm. Wind slabs will be reactive if they settle on slopes that were previously covered with snow.
No avalanche activity was observed or reported.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
Between 20 and 30 cm of new snow is forecast between now and Tuesday evening. The melt-freeze crust from December 20 will then be 30 to 50 cm deep. Snow cover is very unevenly distributed in the mountains due to recent wind events. There is considerable spatial variability, ranging from bare rocky slopes to wind-blown snow accumulations.
Conditions remain typical for the beginning of the season: there are numerous obstacles on the ground.
A winter storm will hit the Gaspé Peninsula on Monday evening and bring 20 to 30 cm of snow by Tuesday evening.
