Weakly bonded old snow is to be evaluated with care and prudence. Gliding avalanches require caution.
Avalanches can be triggered in the old snowpack and reach quite a large size. Avalanche prone locations are to be found in all aspects above approximately 2400 m. Caution is to be exercised in particular along the border with Italy. Defensive route selection is recommended.
In addition an appreciable danger of gliding avalanches exists, in particular on steep sunny slopes below approximately 2600 m, as well as on steep shady slopes below approximately 2400 m. These can reach dangerously large size. Areas with glide cracks are to be avoided as far as possible.
The somewhat older wind slabs can still be released in some cases on very steep shady slopes above approximately 2600 m. This applies especially adjacent to ridgelines. In some cases avalanches are medium-sized.

Outgoing longwave radiation during the night will be reduced. The snowpack will be wet all the way through below approximately 2200 m. The snowpack will be moist below approximately 2400 m.
Afternoon: Above approximately 1500 m snow will fall over a wide area.
New snow and wind slabs are lying on a weakly bonded old snowpack. This applies above approximately 2400 m in all aspects. The somewhat older wind slabs are lying on soft layers in particular on shady slopes. This applies above approximately 2600 m.
Tendency
Weakly bonded old snow represents the main danger. Numerous small and medium-sized loose snow avalanches are to be expected. Gliding avalanches require caution.

Gliding avalanches are the main danger. Fresh wind slabs at high altitude.
An appreciable danger of gliding avalanches exists, in particular on steep sunny slopes below approximately 2600 m, as well as on steep shady slopes below approximately 2400 m. These can reach dangerously large size. Areas with glide cracks are to be avoided as far as possible.
The fresh wind slabs can be released by a single winter sport participant in isolated cases in particular on very steep shady slopes above approximately 2600 m. This applies especially adjacent to ridgelines. In some cases avalanches are medium-sized.
Avalanches can in very isolated cases be triggered in the old snowpack. Avalanche prone locations are to be found in particular on very steep east, north and west facing slopes above approximately 2400 m.

Outgoing longwave radiation during the night will be reduced. The snowpack will be wet all the way through below approximately 2200 m. The snowpack will be moist below approximately 2400 m.
Afternoon: Above approximately 1500 m snow will fall over a wide area.
Fresh and somewhat older wind slabs are lying on soft layers in particular on shady slopes. This applies above approximately 2600 m. In very isolated cases new snow and wind slabs are lying on a weakly bonded old snowpack.
Tendency
Increase in avalanche danger as a consequence of the new snow. Numerous small and medium-sized loose snow avalanches are to be expected. Gliding avalanches require caution.
