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. As a consequence of warming during the day and solar radiation more frequent medium-sized moist loose snow avalanches are to be expected below approximately 2600 m. In addition individual moist slab avalanches are possible. 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.

In some regions up to 50 cm of snow, and even more in some localities, fell in the last two days. As a consequence of wind, avalanche prone wind slabs formed in the last few days, 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. Up to high altitudes rain fell on Wednesday in some regions. Thursday: The surface of the snowpack cooled hardly at all during the overcast night and will soften quickly.

Over a wide area 5 to 10 cm of snow, and even more in some localities, will fall on Friday. As a consequence of the new snow there will be only a slight increase in the avalanche danger.
