Upper Passeier Valley

Fresh wind slabs represent the main danger. Gliding snow requires caution.

Fresh wind slabs represent the main danger. Gliding snow requires caution.

The wind slabs can be released even by a single winter sport participant in particular on steep shady slopes above approximately 2400 m. 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. The avalanche prone locations are to be found in particular on west, north and east facing slopes above approximately 2400 m. Avalanches can in isolated cases penetrate deep layers and reach large size. More frequent medium-sized moist loose snow avalanches are to be expected below approximately 2600 m. In particular in the regions with a lot of snow more frequent medium-sized gliding avalanches are to be expected, especially below approximately 2600 m.

Over a wide area up to 15 cm of snow, and even more in some localities, will fall. As a consequence of new snow and wind the wind slabs will increase in size moderately. They are in some cases prone to triggering, in particular at high altitudes and in high Alpine regions. Isolated avalanche prone weak layers exist deeper in the snowpack in particular on steep east, north and west facing slopes. The snowpack will be moist below approximately 2400 m.

The weather conditions will facilitate a gradual stabilisation of the snowpack.
