Fresh wind slabs are to be evaluated with care and prudence.

As a consequence of a moderate to strong wind from northwesterly directions, wind slabs formed since Tuesday above the tree line. These can be released by a single winter sport participant in some cases. In particular in regions of the north exposed to the foehn wind the avalanche prone locations are more prevalent. The avalanche prone locations are to be found on very steep slopes and adjacent to ridgelines and in gullies and bowls. More dry snow slides and avalanches are possible as the day progresses, even medium-sized ones, especially on extremely steep slopes.

10 to 20 cm of snow fell on Monday in all altitude zones. The upper section of the snowpack is unfavourably layered and its surface consists of loosely bonded snow lying on a crust,, also above approximately 2200 m. Towards its base, the snowpack is largely stable.

The avalanche danger will persist. Thursday: Evening and night: Some snow will fall.
