Stability: poor · Frequency: few
Weakly bonded old snow requires caution.
Distinct weak layers exist in the bottom section of the snowpack in particular above approximately 2000 m. Single winter sport participants can release avalanches in isolated cases. These can reach large size. In particular shady slopes are dangerous. Outgoing longwave radiation during the night will be good over a wide area. As a consequence of warming during the day and solar radiation individual mostly small wet loose snow avalanches are possible below approximately 2200 m.
The snowpack remains unstable in some places. Avalanche prone weak layers exist in the bottom section of the snowpack on shady slopes. The surface of the snowpack will freeze to form a strong crust and will soften during the day.
Weakly bonded old snow requires caution. Increase in danger of wet avalanches as a consequence of warming during the day and solar radiation.
