Weakly bonded old snow is to be evaluated with care and prudence. Wind slabs require caution.

In isolated cases avalanches can be triggered in the weakly bonded old snow and reach large size in isolated cases, in particular on very steep shady slopes above approximately 2400 m. In addition the various wind slabs of the last few days are capable of being triggered in some locations. They are to be evaluated with care and prudence in particular on northwest to north to northeast facing aspects above approximately 2600 m. Avalanches can in isolated cases penetrate deep layers. At elevated altitudes the avalanche prone locations are more prevalent. As the moisture increases more frequent wet avalanches are possible, even medium-sized ones.

As a consequence of new snow and a moderate to strong northwesterly wind, sometimes large wind slabs formed in the last few days. These are lying on soft layers in particular on northwest to north to northeast facing aspects above approximately 2600 m. Avalanche prone weak layers exist in the top section of the snowpack in particular on steep shady slopes. Outgoing longwave radiation during the night will be severely restricted over a wide area. The surface of the snowpack will freeze very little and will soften during the day.

On Friday it will be mild. Some rain will fall over a wide area, especially in the north. Increase in danger of wet avalanches.
