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 wet loose snow avalanches are to be expected, even medium-sized ones. In addition an appreciable danger of gliding avalanches exists, especially on grassy slopes below approximately 2600 m.

Over a wide area up to 15 cm of snow, and even more in some localities, fell on Friday. In some regions up to 10 cm of snow, and even more in some localities, will fall above approximately 1500 m. The snowpack will be moist below approximately 2400 m. The surface of the snowpack will soften during the day. As a consequence of new snow and wind the wind slabs will increase in size. 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.

Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall until Monday. As a consequence of new snow and strong wind the wind slabs will increase in size. Gliding avalanches and moist snow slides require caution.
