Monday will be another sunny day. Remember that with a moderate avalanche danger rating, small avalanches in specific areas or large avalanches in isolated areas are possible to trigger by human intervention. Use safe travel practices during your mountain outings.
The wind slabs that formed over the past few days (Friday to Saturday night) rest on sun crusts or hardened snow, providing a good sliding surface. Their thickness generally varies from 10 to 50 cm, but could be greater depending on their orientation. The light winds and rising temperatures expected on Sunday and Monday will help stabilize them.
On Friday, a slab avalanche accidentally triggered by users during the ascent was reported in the Grande Cuve sector of Mont Albert. For more details, see the MIN
Also on Friday, another slab avalanche accidentally triggered by a skier was reported in Rock'n'roll, in the Mur des Patrouilleurs sector of Mont Albert. For more details, here is the MIN.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
New snow and wind-blown snow have formed wind slabs measuring 10 to 50 cm thick, mainly in alpine terrain and at the tree line, on east, south, and west-facing slopes. These slabs lie on various surfaces, including old wind slabs and refreeze crusts, creating good sliding surfaces in places. Several north and west-facing slopes are bare.
A superimposition of wind slabs of varying densities is present at the top of wind-loaded slopes in alpine areas and at the tree line.
Below the tree line, there is generally 15 to 25 cm of light snow resting on a gradually denser layer.
In the Mines Madeleine sector, as well as locally on Ernest-Laforce and on some east-west slopes, a layer of large, fragile grains is buried under 20 to 50 cm of wind slabs.
The average snowpack depth at mid-mountain is approximately 120 cm.
