Upper Passeier Valley

Fresh wind slabs represent the main danger. Gliding snow requires caution. Wet loose snow avalanches are possible in the afternoon.

Fresh wind slabs represent the main danger. Gliding snow requires caution. Wet loose snow avalanches are possible in the afternoon.

The fresh snow of the weekend and the often large wind slabs can be released by a single winter sport participant in particular on steep shady slopes above approximately 2400 m. This applies especially adjacent to ridgelines. Mostly avalanches are medium-sized. The number and size of avalanche prone locations will increase with altitude. Weak layers in the old snowpack can still be released in very isolated cases by individual winter sport participants. Avalanche prone locations are to be found in particular on very steep west and east facing slopes above approximately 2400 m. Avalanche prone locations are to be found also on very steep north facing slopes above approximately 2100 m. Avalanches can in isolated cases penetrate deep layers and reach large size. As a consequence of the moist air wet loose snow avalanches are possible in the afternoon, even medium-sized ones. This applies in case of a single winter sport participant, especially on extremely steep sunny slopes below approximately 2400 m. In addition an appreciable danger of gliding avalanches exists, especially on grassy 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.

In some regions up to 30 cm of snow, and even more in some localities, fell in the last two days above approximately 1500 m. Outgoing longwave radiation during the night will be reduced. The snowpack will be moist below approximately 2400 m. The surface of the snowpack will soften quickly. As a consequence of new snow and strong wind the wind slabs have increased in size. Fresh and somewhat older wind slabs are lying on soft layers in particular on shady slopes. They are in some cases prone to triggering. This applies above approximately 2400 m. Isolated avalanche prone weak layers exist deeper in the snowpack in particular on steep east, north and west facing slopes. In very isolated cases new snow and wind slabs are lying on a weakly bonded old snowpack.

Fresh wind slabs require caution. Gliding avalanches and moist snow slides require caution.
