Fresh wind slabs are to be evaluated with care and prudence. On steep grassy slopes individual gliding avalanches are possible.
The fresh wind slabs can be released easily, even by a single winter sport participant, on 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. In the regions exposed to the foehn wind these avalanche prone locations are more prevalent. Avalanches can reach medium size in isolated cases especially in these regions. The clearly visible wind slabs are to be avoided.
On steep grassy slopes individual gliding avalanches are possible, especially on sunny slopes below approximately 2400 m. Caution is to be exercised in areas with glide cracks.
Snowpack
dp.6: cold, loose snow and wind dp.2: gliding snow
As a consequence of a strengthening southerly foehn wind, mostly shallow wind slabs formed since Monday in gullies and bowls and behind abrupt changes in the terrain. During the course of the night these will increase in size additionally. The fresh wind slabs are lying on soft layers especially 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.
Tendency
Fresh wind slabs are in some cases prone to triggering. Gliding snow requires caution.

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 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 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.
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.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 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 high temperatures gave rise to moistening of the snowpack at intermediate altitudes.

A little snow is lying. The snowpack will be subject to considerable local variations.

The fresh wind slabs can be released easily by a single winter sport participant on 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 especially in the regions with a lot of snow. The clearly visible wind slabs are to be avoided.
Weak layers in the old snowpack can still be released in some places by individual winter sport participants. The avalanche prone locations are to be found on very steep west, north and east facing slopes above approximately 2200 m. The number and size of avalanche prone locations will increase with altitude. Avalanches can reach medium size. In very isolated cases avalanches can also penetrate deep layers. Such avalanche prone locations are to be found on very steep north facing slopes above approximately 2800 m. Especially in the more southerly regions along the main Alpine ridge and in glaciated terrain.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
As a consequence of a strengthening southerly foehn wind, sometimes avalanche prone wind slabs formed since Monday in gullies and bowls and behind abrupt changes in the terrain. During the course of the night these will increase in size once again. The wind slabs are lying on soft layers especially on west, north and east facing slopes. In some places wind slabs are lying on surface hoar. Towards its base, the snowpack is faceted and weak. This applies especially on west, north and east facing slopes at elevated altitudes, in particular in shady places that are protected from the wind.
Tendency
Wind slabs and weakly bonded old snow require caution.
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. 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.

From a snow sport perspective, insufficient snow is lying.

The somewhat older wind slabs are in individual cases still prone to triggering.
The wind slabs of last week can be released in isolated cases on very steep west, north and east facing slopes. The avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain above approximately 2400 m. The rather small wind slabs are clearly recognisable to the trained eye. 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.

The snowpack will be subject to considerable local variations. From a snow sport perspective, in most cases insufficient snow is lying.

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.
