Wind slabs and weakly bonded old snow require caution.

Wind slabs and weakly bonded old snow require caution.

Weak layers in the old snowpack can be released especially by large additional loads in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. This applies on very steep slopes above approximately 2400 m. Avalanches can reach large size in isolated cases. The fresh and older wind slabs are in some cases prone to triggering in particular on northwest to north to southeast facing aspects above approximately 2400 m. Caution is to be exercised in particular adjacent to ridgelines. On steep grassy slopes more small and, in isolated cases, medium-sized gliding avalanches are possible. This applies in particular in the regions with a lot of snow.

Faceted weak layers exist in the centre of the snowpack in particular above approximately 2400 m. The fresh and somewhat older wind slabs are lying on soft layers in particular on shady slopes at elevated altitudes. The new snow and wind slabs are lying on a crust below approximately 2600 m. As a consequence of new snow and wind the wind slabs will increase in size moderately towards the evening. Towards its base, the snowpack is moist, in particular below approximately 2400 m.

The avalanche danger will persist. As a consequence of new snow and a strong to storm force wind from northwesterly directions, further wind slabs will form.
