Avalanche Activity

The snow sport conditions outside marked and open pistes are quite favourable.

The older wind slabs are in individual cases still prone to triggering, especially on very steep shady slopes in little used backcountry terrain. This applies especially above approximately 2700 m along the border with France and along the border between Valais and Italy. A clear night: Outgoing longwave radiation during the night will be good. The surface of the snowpack will freeze to form a strong crust and will soften during the day.

Snowpack Structure

The wind was light. Sunny slopes: The surface of the snowpack has frozen to form a strong crust and will soften during the day. In shady places that are protected from the wind: Towards its surface, the snowpack is dry and has a loosely bonded surface. Snow depths vary greatly above approximately 2200 m, depending on the infuence of the wind. Adjacent to ridgelines and in pass areas and at high altitude a little snow is lying. At low altitude less snow than usual is lying.

Tendency

The snow sport conditions outside marked and open pistes are quite favourable.
