In very isolated cases avalanches can be released in the old snowpack and reach medium size. This applies even in case of a single winter sport participant in isolated cases, especially above approximately 1900 m on northwest, north and northeast facing slopes. Individual mostly small wet avalanches are possible. Many starting zones have released the snow.
Distinct weak layers exist in the old snowpack in particular on northeast, north and northwest facing slopes. This applies especially above approximately 1900 m. Outgoing longwave radiation during the night was good over a wide area. Towards its surface, the snowpack consists of faceted crystals, especially in areas where the snow cover is rather shallow on shady slopes. Outgoing longwave radiation during the night will be quite good at times. The surface of the snowpack will freeze to form a strong crust. There is a danger of falling on the hard crust. The weather conditions as the day progresses will give rise to softening of the snowpack in particular on very steep sunny slopes. Backcountry tours should be started early and concluded timely.
Weakly bonded old snow requires caution. Slight increase in danger of wet avalanches as a consequence of warming during the day and solar radiation. After an overcast night this applies.
