The main problem is a persistent weak layer in persistent weak layer, fresh wind slab is temporarily prone to triggering
The avalanche risk is moderate above around 2000 metres and low below. With the southerly foehn, fresh, prone-to-triggering pillows of wind drifted snow develop, which can easily be triggered by individuals in a few places, especially in the extended northern exposures. In addition, in the aspects from west to north to east, medium and occasionally large, dry slab avalanches can still be triggered by individuals in a few places. Danger areas are difficult to recognise away from freshly formed drift snow packs. Take particular care at the transitions from little to more snow. The likelihood of gliding avalanches remains somewhat increased.
Snowpack
During the partly cloudy night, only a thin melt-freeze crust forms, which softens again during the day. In shady high altitudes, soft, faceted snow can often still be found on the surface, which can be partly transported in the foehn aisles and partly overlaid by fresh wind slab in windless areas. Below this lies a well-set sequence of compact, older drift snow layers, in which a crust is embedded in combination with faceted crystals. The connection at the transition to the old snow foundation, which consists mainly of deep rime, is still poor. Deep and sunny middle layers are largely snowed out.
Tendency
The southerly foehn subsides and it snows unproductively. The avalanche danger does not change significantly.

Note the persistent weak layer
The avalanche risk is low. Medium-sized slab avalanches can still be triggered in a few hard-to-recognise places, especially in the extended northern sector above 1800 m, but usually only with a large additional load. This is in particular at the transitions from little to more snow. Occasionally, fresh, small-scale pillows of wind drifted snow develop that are temporarily prone to triggering.
Snowpack
During the partly cloudy night, only a thin melt-freeze crust forms, which softens again during the day. In shady high altitudes, soft, faceted snow can often still be found on the surface, which can be transported in particularly susceptible foehn lines. Below this lies a well-set sequence of compact, older drift snow layers, in which a crust is embedded in combination with faceted crystals. The connection at the transition to the old snow foundation, which consists mainly of deep rime, is still poor. Deep and sunny middle layers are largely snowed out.
Tendency
The southerly wind is easing and it's not snowing heavily. The avalanche risk does not change significantly.
Danger level
Low risk of isolated wet snow avalanches
The avalanche risk is low. In exceptional cases, small snow slabs can still be triggered in the entrance areas of steep gullies on the shady slopes with a large additional load. The risk of being swept away and falling on icy surfaces generally outweighs the risk of burial.
Snowpack
Low and sunny mid-altitude areas are snowed out. Where present, the snowpack is moist to wet and well-set right up to the summit areas. During the partly cloudy night, only a thin melt-freeze crust forms, which softens again during the day. In the higher areas on shady slopes, there are still weak layers of large faceted crystals in the lower part of the snowpack, especially close to the ground.
Tendency
There is unproductive precipitation. The avalanche danger does not change significantly.
