(--), in the regions exposed to heavier precipitation caution is to be exercised on wind-loaded slopes, in particular along the border with France.

As a consequence of new snow and a moderate to strong wind from northwesterly directions, wind slabs formed. This applies especially adjacent to ridgelines and in gullies and bowls. In particular in regions exposed to heavier precipitation the avalanche prone locations are more prevalent. The new snow and wind slabs can be released by a single winter sport participant above approximately 2200 m, in particular on steep slopes, and at transitions from a shallow to a deep snowpack. Avalanches can also be triggered in the old snowpack and reach large size in isolated cases. This applies in particular on shady slopes at elevated altitudes.

Especially in the regions exposed to the foehn wind snowfall. The wind will be moderate to strong. These weather conditions will give rise to unfavourable bonding of the snowpack. Wind slabs will form in particular in gullies and bowls, and behind abrupt changes in the terrain. Adjacent to ridgelines and in pass areas as well as in high Alpine regions snow depths vary greatly, depending on the infuence of the wind. Individual weak layers exist in the snowpack on shady slopes, especially on steep slopes above approximately 2400 m.
