Avalanche Activity

Gliding avalanches are the main danger. Fresh wind slabs at high altitude. Wet loose snow avalanches are possible especially in the afternoon.

An appreciable danger of gliding avalanches exists, in particular on steep sunny slopes below approximately 2600 m, as well as on steep shady slopes below approximately 2400 m. These can reach dangerously large size. Areas with glide cracks are to be avoided as far as possible. As a consequence of the moist air wet loose snow avalanches are possible as the day progresses, even medium-sized ones. This applies in case of a single winter sport participant, especially on extremely steep slopes below approximately 2400 m. The fresh wind slabs can be released by a single winter sport participant in isolated cases in particular on very steep shady slopes above approximately 2600 m. This applies especially adjacent to ridgelines. In some cases avalanches are medium-sized. The number and size of avalanche prone locations will increase with altitude. Avalanches can in very isolated cases be triggered in the old snowpack. Avalanche prone locations are to be found in particular on very steep east and west facing slopes above approximately 2400 m. Avalanche prone locations are to be found also on very steep north facing slopes above approximately 2100 m.

Snowpack Structure

Outgoing longwave radiation during the night will be reduced. The surface of the snowpack will soften during the day. The snowpack will be wet all the way through below approximately 2200 m. The snowpack will be moist below approximately 2400 m. Fresh and somewhat older wind slabs are lying on soft layers in particular on shady slopes. This applies above approximately 2600 m. In very isolated cases new snow and wind slabs are lying on a weakly bonded old snowpack.

Tendency

Gliding avalanches are the main danger.
