Weak layers in the old snowpack can be released in isolated cases.
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 and solar radiation individual small and medium-sized wet avalanches are to be expected.
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 quite good over a wide area. The weather conditions as the day progresses will give rise to thorough wetting of the snowpack.
Wet snow requires caution.
