A dangerous avalanche situation will be encountered over a wide area. The danger exists in particular in alpine snow sports terrain.
Avalanches can be released in the weakly bonded old snow very easily. This applies in particular on west, north and east facing slopes above the tree line, in isolated cases also on south facing slopes above approximately 2200 m. Avalanches can reach large size. Remotely triggered avalanches are probable.
The avalanche prone locations are widespread and are barely recognisable. The number and size of avalanche prone locations will increase with altitude. Fresh avalanches and whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.
Great caution and restraint are required.
Snowpack
dp.5: snowfall after a long period of cold dp.6: cold, loose snow and wind
In some regions up to 80 cm of snow, and even more in some localities, has fallen since Saturday.
The new snow and wind slabs are lying on top of a weakly bonded old snowpack. The old snowpack is faceted. This applies especially in shady places that are protected from the wind.
Tendency
Avalanches can as before be released very easily. The snowpack remains prone to triggering over a wide area.

A precarious avalanche situation will prevail. The avalanche danger is within the upper range of danger level 3 (considerable).
Avalanches can be released in the weakly bonded old snow very easily. This applies in particular on west, north and east facing slopes above the tree line, in isolated cases also on south facing slopes at elevated altitudes. Mostly the avalanches in these loacations are medium-sized. Remotely triggered avalanches are possible.
The avalanche prone locations are widespread and are barely recognisable. Individual avalanche prone locations are to be found also in areas close to the tree line. The number and size of avalanche prone locations will increase with altitude. Fresh avalanches and whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.
Caution and restraint are required.

Weak layers in the old snowpack necessitate caution.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 2200 m. Mostly avalanches are medium-sized.
Caution is to be exercised in particular in gullies and bowls, as well as at transitions from a shallow to a deep snowpack. The avalanche prone locations are covered with new snow and are difficult to recognise. The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger.

10 cm of snow, and even more in some localities, has fallen.
The new snow and wind slabs are lying on top of a weakly bonded old snowpack. They are poorly bonded with the old snowpack. The old snowpack is faceted.
The snowpack will be generally subject to considerable local variations.
Tendency
Avalanches can be released by a single winter sport participant.

Wind slabs and weakly bonded old snow represent the main danger.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above the tree line. In isolated cases avalanches are medium-sized.
In addition the fresh and older wind slabs are capable of being triggered.
Caution is to be exercised in particular in gullies and bowls, as well as at transitions from a shallow to a deep snowpack. The avalanche prone locations are sometimes covered with new snow. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger.
