Weak layers in the old snowpack can still be released in isolated cases.
Avalanches can in isolated cases be released in the old snowpack and reach medium size in isolated cases on northwest, north and northeast facing slopes. This applies in case of a single winter sport participant. In their paths avalanches can entrain the wet snow. As a consequence of warming during the day individual wet avalanches are possible.
Shady slopes: Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. The weather conditions gave rise to moistening of the snowpack below approximately 1800 m.
Weakly bonded old snow requires caution. Slight increase in danger of wet avalanches as a consequence of warming during the day and solar radiation.
