A weather front will bring new precipitation accompanied by strong winds — the perfect combo for the formation of new wind slabs. The danger rating rises to Considerable, so careful terrain management is advised.
With new snow and strong west winds, reactive wind slabs are expected to form on northeast through southeast aspects. These slabs will form over older, more stubborn wind slabs. The new slabs could reach 10 to 40 cm in thickness.
A size 2 avalanche on a northeast aspect was reported in the Cuve des Mélèzes. It is believed to have occurred early Tuesday morning and was likely triggered by a user. The avalanche was reported on the Mountain Information Network (MIN). If you have additional information about this event, please contact us. This information is very valuable and helps improve the quality of our forecasts.
If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).
Up to 10 cm of new snow could fall by Wednesday evening.
In the alpine and at treeline, conditions are highly variable, with wind-hardened snow, pockets of powder, wind slabs of varying densities, and areas scoured down to bare ground, particularly on west- and south-facing slopes.
Below treeline, 20 to 40 cm of light snow overlies a progressively denser snowpack, down to basal weak layers of faceted grains and depth hoar.
On solar aspects, a sun crust is present 5 to 30 cm below the surface.
At mid-elevation, the average snowpack depth is around 130 cm.
