Wind slabs can be released easily.

Wednesday: 10 to 20 cm of snow, and even more in some localities, fell by the evening. In the last few days the wind was moderate to strong over a wide area. Forming both soft and hard slabs. Faceted weak layers exist in the old snowpack in particular on north, east and west facing slopes. Along the border with France and along the border with Switzerland: Numerous medium-sized and, in isolated cases, large natural avalanches have been released on Thursday. Artificially triggered avalanches and naturally triggered avalanches have shown an unfavourable avalanche situation.

On Sunday the wind will be moderate. These meteorological conditions will cause a slow decrease in the avalanche danger.

Wind slabs can be released easily.

As a consequence of new snow and a moderate wind from variable directions, sometimes deep wind slabs formed in the last few days in all aspects. They are lying on top of a weakly bonded old snowpack. Single winter sport participants can release avalanches as before, including medium-sized ones, caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain, and on very steep slopes. Very steep west, northwest and north facing slopes: The avalanches can be triggered in deep layers of the snowpack. These can be released, in particular by large loads and reach large size in isolated cases. Remotely triggered avalanches are possible. Backcountry touring and other off-piste activities call for caution. Careful route selection and spacing between individuals are recommended. In addition further individual small and medium-sized natural avalanches are possible.
