Weak layers in the old snowpack can be released in isolated cases. The danger of wet avalanches will increase a little during the day.
Avalanches can in isolated cases be released in the old snowpack and reach medium size on west, north and east 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.
Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. Outgoing longwave radiation during the night will be reduced in some case. The weather conditions as the day progresses will give rise to gradual softening of the snowpack.
Weakly bonded old snow and wet snow require caution.
