A little more snow is expected this Friday. Assess the reactivity of wind slabs when traveling.
The tests we conducted at treeline showed that the wind slabs were highly reactive, as they are based on facets that formed on the crust of December 20. The new snow expected on Friday should form new wind slabs that will overlie the old ones.
We received 15 cm of snow during Monday night's storm. This snow is still light in areas sheltered from the wind. Facets formed on the breakable melt-freeze crust from December 20, located between 10 and 30 cm deep.
Snow is very unevenly distributed in the alpine and at treeline due to recent wind events, ranging from bare rocky slopes to wind-blown snow accumulations.
No avalanche activity was observed or reported.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
A new winter storm rapidly intensifying will gradually affect the Gaspé Peninsula starting late Thursday afternoon.
