Weakly bonded old snow and wet snow represent the main danger.
Avalanches can be released in the old snowpack and reach quite a large size on west, north and east facing slopes. This applies even in case of a single winter sport participant in some cases. The avalanche prone locations are to be found in particular above approximately 2000 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. In their paths avalanches can entrain the wet snow. This extends the avalanche runout distances. Outgoing longwave radiation during the night will be severely restricted. Individual small and, in isolated cases, medium-sized wet avalanches are possible below approximately 2200 m.
Shady slopes: Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. This applies especially above approximately 2000 m. The surface of the snowpack will only just freeze. The weather conditions gave rise to thorough wetting of the snowpack below approximately 2200 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.
