Weakly bonded old snow requires caution. Wet snow requires caution.
Even single winter sport participants can release avalanches in some places. In particular shady slopes are dangerous, especially in areas close to the tree line, as well as above the tree line. Outgoing longwave radiation during the night will be severely restricted over a wide area. Individual small and, in isolated cases, medium-sized wet loose snow avalanches are possible below approximately 2200 m. In addition gliding avalanches are possible. This applies especially on cut and grassy slopes.
Some snow will fall in some regions. The weather will be mild. The snowpack remains unstable in some places. Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning.
Weakly bonded old snow requires caution. Single winter sport participants can release avalanches as before. The weather will be sunny over a wide area. Slight increase in danger of wet avalanches as a consequence of warming during the day and solar radiation.
