Snowfall amounts are uncertain. Pay particular attention to the formation of new wind slabs and their reactivity.
Depending on the amount of snow expected between now and Monday evening, wind slabs could form on leeward slopes. They will rest on a melt-freeze crust, providing an excellent sliding surface.
No new avalanche observed or reported.
If you are heading into the backcountry, please share your observations on the Mountain Information Network (MIN).
At the surface, a melt-freeze crust is present up to the alpine. The snowfall expected on Sunday night will accumulate on this crust. In the alpine and at treeline, conditions vary greatly between different aspects, but especially between different mountains. We find either surface rock, ice, crusted snow or wind-hardened snow accumulations.
The middle of the snowpack consists of alternating well-consolidated snow and melt-freeze crusts. At mid-mountain, the depth of the snowpack varies from 60 to 180 cm.
Snowy precipitation is expected during the week.
Sunday evening and night: Rain changing to snow this evening. Snow accumulation of 5 to 10 cm. Northeast winds, 30 to 60 km/h. Low -2. Freezing level at 300 m.
Monday: Snow. Accumulation of 3 to 5 cm. Northeast winds, 30 to 50 km/h. Maximum -1. Freezing level at 600 m.
Tuesday: Alternating sun and clouds. Northeast winds, 10 to 20 km/h. High 3. Freezing level at 900 m.
Wednesday: Snow. Accumulation of 15 to 20 cm. Light northeast winds. Maximum 1. Freezing level at 600 m.
