Below approximately 3400 m the danger of moist and wet avalanches will increase to level 3 (considerable) in the late morning.

Below approximately 3400 m the danger of moist and wet avalanches will increase to level 3 (considerable) in the late morning.

The spring-like weather conditions in the late morning will give rise to a loss of strength within the snowpack. This applies in particular on steep east, south and west facing slopes in particular at intermediate and high altitudes, as well as on shady slopes below approximately 2600 m. More medium-sized and, in isolated cases, large moist and wet avalanches are possible. They can occur in particular in starting zones where previous releases have taken place. In addition a danger of ground avalanches exists, in particular on steep grassy slopes. Backcountry tours, off-piste skiing and ascents to alpine cabins should be started and concluded very early. The conditions are to some extent favourable in the morning for winter sport activities. Faceted weak layers exist in the top section of the snowpack. Single winter sport participants can release avalanches in some places, including medium-sized ones. These avalanche prone locations are to be found in particular on steep north, northeast and northwest facing slopes above approximately 2600 m.

The surface of the snowpack will freeze to form a strong crust only at high altitudes and will already be soft in the early morning. Towards its surface, the snowpack is unfavourably layered. Less snow than usual is lying. On sunny slopes below approximately 2200 m from a snow sport perspective, insufficient snow is lying. In the last three days on steep sunny slopes several small and, in isolated cases, medium-sized avalanches were reported. This applies in all aspects in particular between approximately 2400 and 2800 m, as well as on sunny slopes in high Alpine regions.

The conditions remain spring-like.
