Wind slabs and weakly bonded old snow represent the main danger.

Wind slabs and weakly bonded old snow represent the main danger.

As a consequence of snowfall and the strong to storm force southwesterly wind, the snow drift accumulations have increased in size on Wednesday. The fresh wind slabs will be covered with new snow and therefore difficult to recognise. In particular on steep west, north and east facing slopes avalanches can be triggered in the weakly bonded old snow and reach medium size. Caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain, as well as in places that are protected from the wind. The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Remotely triggered avalanches are possible in isolated cases. Restraint is advisable.

Up to 10 cm of snow, and even more in some localities, has fallen. Up to 15 cm of snow, and even more in some localities, will fall. This applies in particular in the south. The new snow and wind slabs are lying on surface hoar in some places in particular on shady slopes above approximately 2000 m. As a consequence of a strong to storm force wind from southerly directions, further wind slabs formed. These are lying on top of a weakly bonded old snowpack above approximately 2000 m. The old snowpack is faceted and weak. This applies especially in shady places that are protected from the wind.

Hardly any decrease in avalanche danger. The current avalanche situation calls for caution and restraint.
