Slab avalanches are the main danger.

Slab avalanches are the main danger.

The fresh wind slabs represent the main danger. These can as before be released, in particular by large loads. Dry avalanches can in isolated cases be released in near-ground layers and reach medium size. The avalanche prone locations are to be found in particular in extremely steep terrain and at transitions into gullies and bowls, this also applies adjacent to ridgelines and in pass areas at intermediate and high altitudes. Transitions from a shallow to a deep snowpack where weaknesses exist in the old snowpack are especially unfavourable. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate the danger.

As a consequence of a moderate to strong wind from northeasterly directions, visible wind slabs formed by Thursday in particular adjacent to ridgelines and in gullies and bowls. In particular at intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. Faceted weak layers exist in the bottom section of the snowpack at intermediate and high altitudes. In all aspects below approximately 2000 m from a snow sport perspective, in most cases insufficient snow is lying.

The weather will be sunny. The wind will be moderate to strong adjacent to ridgelines. The avalanche danger will increase a little during the day.
