A partly overcast night. In some localities precipitation.

Outgoing longwave radiation during the night will be reduced over a wide area. The surface of the snowpack will freeze to form a strong crust only at high altitudes. In some localities light precipitation. A little new snow above approximately 2500 m. As the day progresses the likelihood of moist and wet avalanches being released will increase a little. Such avalanche prone locations are to be found in particular at the base of rock walls below approximately 2800 m and in steep rocky terrain. Individual mostly small natural avalanches are possible. Individual avalanche prone locations are to be found adjacent to ridgelines above approximately 2800 m. In very isolated cases the avalanches can be triggered in deep layers of the snowpack. This applies on very steep shady slopes above approximately 2800 m.

The new snow of recent weeks has settled to a large extent in all aspects. This snow remains in some cases prone to triggering on very steep shady slopes above approximately 2800 m. The snowpack will be quite moist. The old snowpack is unfavourably layered. In the last two days hardly any more avalanches were reported. At low and intermediate altitudes from a snow sport perspective, insufficient snow is lying.

In some localities light precipitation. The weather conditions will cause a slight rise in the avalanche danger as the day progresses especially at high altitude.
