Weakly bonded old snow is to be avoided. Wind slabs require caution.
Winter sport participants can release avalanches in isolated cases. They can be triggered in deep layers 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. Wind slabs can still be released at elevated altitudes. This applies in particular in case of a large load. Avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. Avalanches can reach medium size in isolated cases.
The old snowpack will be weakly bonded, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes. The sometimes storm force wind has transported the fresh and old snow significantly. Hard wind slabs formed. The various wind slabs have bonded quite well together.
Weakly bonded old snow requires caution.
