Weak layers in the old snowpack are treacherous. In addition the further wind slabs should be taken into account.
The new snow and wind slabs of the last few days are lying on the unfavourable surface of an old snowpack on northwest to north to east facing aspects. Single winter sport participants can release avalanches in some places. In some places the avalanches can be triggered in the faceted old snow, in particular on very steep slopes. The avalanche prone locations are to be found in particular in little used terrain. Remotely triggered avalanches are possible. Several mostly small natural avalanches are possible.
15 to 25 cm of snow, and even more in some localities, has fallen since Tuesday above approximately 2000 m. Several small dry slab avalanches have been released by people. Large-grained weak layers exist in the old snowpack on shady slopes. The new snow of the last few days is lying on surface hoar in some places. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. The numerous rocks hidden by the recent snow are the main danger.
The weather will be sunny.
