In particular very steep sunny slopes base of rock walls: The danger of moist and wet avalanches will increase a little during the day.

Early morning: In steep terrain there is a danger of falling on the hard snow surface. The surface of the snowpack has frozen to form a strong crust and will soften later than the day before. In particular very steep sunny slopes and base of rock walls: Medium-sized wet and gliding avalanches are to be expected below approximately 2300 m. Weak layers exist deeper in the snowpack. Single winter sport participants can release avalanches in some places. These can be triggered in deep layers and reach large size. These avalanche prone locations are barely recognisable, even to the trained eye. Remotely triggered avalanches are possible in isolated cases.

Outgoing longwave radiation during the night will be severely restricted. The surface of the snowpack will freeze to form a strong crust. The weather conditions will give rise to moistening of the snowpack in particular on steep sunny slopes below approximately 2300 m. Sunday: In some regions some new snow above approximately 1500 m. The weather conditions fostered a stabilisation of the snow drift accumulations in particular on sunny slopes. In its middle, the snowpack is unfavourably layered. Adjacent to ridgelines and in pass areas snow depths vary greatly, depending on the infuence of the wind. There are large frames on the crest. Numerous medium-sized to large moist and wet avalanches have been released in the last few days.

As the temperature drops only isolated moist and wet avalanches are to be expected. Light precipitation in the south-eastern sector, snow at 1200-1500 m. New snow is lying on a hard crust.
