The fresh wind slabs can be released in isolated cases on very steep west, north and east facing slopes above approximately 2200 m. Such avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. In the regions exposed to the foehn wind these avalanche prone locations are more prevalent and larger. Avalanches can reach medium size especially in these regions. The clearly visible wind slabs are to be avoided.
On steep grassy slopes individual gliding avalanches are possible, but they will be mostly small. This applies on sunny slopes below approximately 2400 m.
Snowpack
dp.6: cold, loose snow and wind dp.2: gliding snow
As a consequence of a moderate to strong southerly foehn wind, mostly shallow wind slabs formed since Monday in gullies and bowls and behind abrupt changes in the terrain. The fresh wind slabs are lying on soft layers on west, north and east facing slopes. In some places wind slabs are lying on surface hoar. Isolated avalanche prone weak layers exist in the bottom section of the snowpack on shady slopes. This applies in particular in places that are protected from the wind at elevated altitudes.

Fresh wind slabs can be released in isolated cases.

Wind slabs require caution. Weakly bonded old snow at elevated altitudes.
The fresh and older wind slabs can be released by a single winter sport participant in isolated cases on very steep shady slopes. Such avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain above approximately 2400 m. Avalanches can reach medium size in isolated cases. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
In isolated cases avalanches can also be released in near-ground layers, in particular on very steep shady slopes at elevated altitudes. Steep, glaciated terrain must also be critically assessed.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
A little snow is lying. The snowpack will be subject to considerable local variations. The fresh and somewhat older wind slabs are lying on top of a weakly bonded old snowpack on shady slopes at elevated altitudes. Faceted weak layers exist in the bottom section of the old snowpack in shady places that are protected from the wind.

Wind slabs and weakly bonded old snow require caution.

Wind slabs represent the main danger.
The wind slabs can be released by a single winter sport participant in isolated cases especially on very steep west, north and east facing slopes. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain above approximately 2400 m. Avalanches can reach medium size. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
In isolated cases avalanches can also be released in near-ground layers, in particular on very steep shady slopes at elevated altitudes. The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
Some snow fell in the last two days in some localities. In all regions a little snow is lying. The snowpack will be subject to considerable local variations. The somewhat older wind slabs are lying on top of a weakly bonded old snowpack on west, north and east facing slopes at elevated altitudes. Faceted weak layers exist in the bottom section of the old snowpack in shady places that are protected from the wind. The autumnal weather conditions gave rise to moistening of the snowpack at intermediate altitudes.
The fresh wind slabs can be released even by a single winter sport participant on very steep west, north and east facing slopes above approximately 2200 m. Avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. Avalanches can reach medium size. The clearly visible wind slabs are to be avoided.
Weak layers in the old snowpack can still be released in isolated cases by individual winter sport participants. Such avalanche prone locations are to be found in particular on very steep shady slopes at elevated altitudes. Avalanches can reach medium size. In very isolated cases avalanches can also penetrate deep layers. This applies on very steep north facing slopes above approximately 2800 m.

As a consequence of a moderate to strong southerly foehn wind, wind slabs formed since Monday in gullies and bowls and behind abrupt changes in the terrain. The wind slabs are lying on soft layers on west, north and east facing slopes. In some places wind slabs are lying on surface hoar. Faceted weak layers exist in the bottom section of the old snowpack. This applies especially on west, north and east facing slopes above approximately 2200 m, in particular in shady places that are protected from the wind. Field observations confirm the existence of a weak snowack especially in high Alpine regions.
Tendency
Wind slabs and weakly bonded old snow require caution.
Danger level
Wind slabs require caution.
The wind slabs can be released in isolated cases on very steep west, north and east facing slopes. Restraint should be exercised because avalanches can sweep people along and give rise to falls.
Snowpack
dp.6: cold, loose snow and wind
The autumnal weather conditions gave rise to moistening of the snowpack at intermediate altitudes. Some snow fell in the last two days in some localities. From a snow sport perspective, in most cases insufficient snow is lying. The snowpack will be subject to considerable local variations. Somewhat older wind slabs are lying on top of a weakly bonded old snowpack especially on steep shady slopes. The autumnal weather conditions gave rise to moistening of the snowpack at intermediate altitudes.
Tendency
Thursday: The avalanche danger will persist.
Danger level
Individual avalanche prone locations for dry avalanches are to be found in particular on shady slopes above approximately 2400 m.
The somewhat older wind slabs can be released in isolated cases, but mostly only by large additional loads, on very steep shady slopes. Individual avalanche prone locations are to be found in gullies and bowls above approximately 2400 m. The mostly small wind slabs are clearly recognisable to the trained eye. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack
The snowpack will be subject to considerable local variations. From a snow sport perspective, in most cases insufficient snow is lying. The moderate wind will transport only a little snow. Somewhat older wind slabs are lying on top of a weakly bonded old snowpack on steep shady slopes.
Tendency
From a snow sport perspective, in most cases insufficient snow is lying. Individual avalanche prone locations are to be found at elevated altitudes.
Danger level
Low avalanche danger will prevail.
Avalanches can in very isolated cases be released, but they will be small in most cases. This applies especially on very steep shady slopes at elevated altitudes.

Thus far only a little snow is lying. Wind slabs and gliding snow require caution.
The fresh wind slabs can be released in isolated cases on very steep west, north and east facing slopes at elevated altitudes. The avalanche prone locations are to be found especially adjacent to ridgelines and in pass areas. The small wind slabs are to be avoided in particular in terrain where there is a danger of falling.
On steep grassy slopes individual gliding avalanches are possible, but they will be mostly small.
Snowpack
dp.6: cold, loose snow and wind dp.2: gliding snow
As a consequence of a moderate southerly foehn wind, mostly shallow wind slabs formed since Monday especially in the vicinity of peaks. The clearly visible wind slabs are lying on soft layers on west, north and east facing slopes. In some places wind slabs are lying on surface hoar.
Tendency
Wind slabs are small and can only be released in isolated cases.
