Fresh wind slabs represent the main danger. Weakly bonded old snow requires caution.

Fresh wind slabs represent the main danger. Weakly bonded old snow requires caution.

The fresh wind slabs can be released, even by a single winter sport participant and reach medium size. The avalanche prone locations are to be found in particular on steep shady slopes. At high altitudes and in high Alpine regions the avalanche prone locations are present in all aspects. These avalanche prone locations are sometimes covered with new snow and are difficult to recognise. As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase. More frequent small and, in isolated cases, medium-sized loose snow avalanches are to be expected. In isolated cases avalanches can also release deeper layers of the snowpack and reach large size, especially on very steep west, north and east facing slopes above approximately 2400 m.

In some places wind slabs are lying on soft layers. The meteorological conditions will cause a weakening of the near-surface layers as the day progresses. Faceted weak layers exist in the old snowpack on very steep west, north and east facing slopes, especially above approximately 2400 m on the Main Alpine Ridge.

Hardly any decrease in danger. As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase appreciably. More frequent loose snow avalanches are possible as the day progresses.
