Wind slabs represent the main danger. Weakly bonded old snow is to be evaluated with care and prudence.
As a consequence of new snow and a strong to storm force wind, clearly visible wind slabs formed in all aspects. These can be released easily above approximately 2200 m. Caution is to be exercised in particular at the base of rock walls and behind abrupt changes in the terrain, as well as adjacent to ridgelines and in gullies and bowls. Mostly avalanches are medium-sized. Shooting cracks when stepping on the snowpack can indicate the danger.
Additionally in isolated cases avalanches can penetrate near-ground layers of the snowpack and reach large size, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes.
Loose snow avalanches are possible, but they will be mostly small. In the event of solar radiation this applies in particular, especially on extremely steep slopes.
Snowpack

10 to 20 cm of snow, and even more in some localities, fell in the last few days. The sometimes storm force wind has transported the new snow. In some cases the various wind slabs have bonded poorly together.
The old snowpack will be weakly bonded in some places, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes.
Tendency
Gradual decrease in danger of dry avalanches as a consequence of warming.

New snow and wind slabs represent the main danger.
The large quantity of fresh snow and the extensive wind slabs can be released easily, even by a single winter sport participant,. The fresh and older wind slabs are covered with new snow and therefore difficult to recognise. Avalanches can reach medium size, especially above approximately 2200 m.
Avalanches can in isolated cases penetrate near-ground layers of the snowpack and reach large size, especially on very steep west, north and east facing slopes above approximately 2200 m.
Isolated small and medium-sized gliding avalanches are possible in particular on very steep grassy slopes.
In addition small to medium-sized loose snow avalanches are possible, in the event of prolonged bright spells especially on extremely steep slopes.

New snow and weakly bonded old snow are to be assessed with care and prudence.
Avalanches can in some cases be released in the old snowpack and reach large size, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Remotely triggered avalanches are possible in isolated cases.
The no longer entirely fresh wind slabs can be released by a single winter sport participant above the tree line. Such avalanche prone locations are covered with new snow and are therefore difficult to recognise. Caution is to be exercised in particular at the base of rock walls and behind abrupt changes in the terrain, as well as adjacent to ridgelines and in gullies and bowls. Avalanches can reach medium size.
In addition small and medium-sized loose snow avalanches are possible, in the event of prolonged bright spells especially on extremely steep slopes.

The old snowpack will be weakly bonded in some places, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes in high Alpine regions.

Winter sport participants can release avalanches in isolated cases. They can be triggered in the old snowpack and reach medium size. Caution is to be exercised in particular on very steep west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes. Especially transitions from a shallow to a deep snowpack are unfavourable. Avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain.

Wind slabs represent the main danger. Weakly bonded old snow requires caution.
As a consequence of a storm force wind from northerly directions, clearly visible wind slabs formed in all aspects. These can be released even by a single winter sport participant above approximately 2200 m.

The no longer entirely fresh wind slabs of the last few days can be released by a single winter sport participant. Such avalanche prone locations are to be found in particular in areas close to the tree line and above the tree line. Caution is to be exercised in particular on wind-loaded slopes, as well as in gullies and bowls, and behind abrupt changes in the terrain.
Additionally in very isolated cases avalanches can penetrate near-ground layers of the snowpack and reach medium size, especially on shady slopes at elevated altitudes.
