In sintesi

Wind slabs and wet snow represent the main danger. As a consequence of a strong wind, easily released wind slabs formed adjacent to ridgelines in all aspects.

Avalanche Activity

Wind slabs and wet snow represent the main danger. As a consequence of a strong wind, easily released wind slabs formed adjacent to ridgelines in all aspects.

In the last few days mostly small wind slabs formed as well. The avalanche prone locations are clearly recognisable to the trained eye, especially adjacent to ridgelines, in particular in the central part of the main Alpine ridge. Weak layers exist in the snowpack in shady places that are protected from the wind. Dry avalanches can still be released, mostly by large loads. As a consequence of the rain more mostly small moist and wet avalanches are possible below approximately 2300 m.

Snowpack Structure

Large-grained weak layers exist in the snowpack on shady slopes. This applies especially at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Some fresh snow and in particular the mostly small wind slabs that are forming at high altitude will be deposited on a weakly bonded old snowpack. The rain will give rise as the day progresses to rapid moistening of the snowpack in some places below approximately 2300 m.
