Avalanche Activity

The fresh wind slabs represent the main danger.

The more recent wind slabs can be released easily or naturally above approximately 2400 m. This applies in particular on steep slopes, and in gullies and bowls, and behind abrupt changes in the terrain. Avalanches can also be released in the old snowpack and reach medium size in particular on steep shady slopes. These avalanche prone locations are difficult to recognise.

Snowpack Structure

Outgoing longwave radiation during the night was quite good. In shady places that are protected from the wind intermediate and high altitudes: Towards its surface, the snowpack is fairly homogeneous; its surface is loosely bonded and consists of surface hoar and faceted crystals. Very steep sunny slopes: Towards its surface, the snowpack is largely stable and its surface has a melt-freeze crust that is strong in many cases. Towards its base, the snowpack is faceted. This applies in particular on steep east, north and northwest facing slopes,.

Tendency

The weather will be mild. Gradual decrease in avalanche danger.
