Weakly bonded old snow and wet snow represent the main danger.
Distinct weak layers exist in the bottom section of the snowpack in particular above approximately 2000 m. Winter sport participants can release avalanches in some places. These can penetrate deep layers and reach large size, especially on west, north and east facing slopes. Individual avalanche prone locations are to be found also on southeast, south and southwest facing slopes above approximately 2400 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Remotely triggered avalanches are possible. As a consequence of warming during the day and solar radiation more wet avalanches are to be expected as the day progresses. This applies in particular on steep sunny slopes below approximately 2400 m. In particular on steep, rather lightly snow-covered east and west facing slopes the wet avalanches can penetrate even deep layers and reach large size in isolated cases. In addition gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 2400 m.
The weather will be very warm. The snowpack remains prone to triggering. Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The surface of the snowpack will freeze to form a strong crust and will soften during the day. Sunshine and high temperatures will give rise as the day progresses to extreme and thorough wetting of the snowpack in particular on steep sunny slopes below approximately 2400 m.
Little snow will fall. Avalanches can be released in the weakly bonded old snow by a single winter sport participant. The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. The danger of wet snow slides and avalanches will already exist in the early morning.
