In sintesi

New snow and wet snow represent the main danger. As the precipitation becomes more intense the avalanche prone locations will become more prevalent. As a consequence of a strong wind, easily released wind slabs formed adjacent to ridgelines in all aspects.

Avalanche Activity

New snow and wet snow represent the main danger. As the precipitation becomes more intense the avalanche prone locations will become more prevalent. As a consequence of a strong wind, easily released wind slabs formed adjacent to ridgelines in all aspects.

During the course of the night as a consequence of the rain there will be an additional increase in the danger of wet avalanches. This applies in particular below approximately 2600 m. Especially on very steep west, north and east facing slopes and below approximately 2600 m more frequent wet slab avalanches are to be expected as the penetration by moisture increases. These can release the saturated snowpack and reach large size also in the regions with a lot of snow. Fresh wind slabs can be released by a single winter sport participant in some cases in particular on very steep shady slopes above approximately 2600 m. Such avalanche prone locations are to be found adjacent to ridgelines and in gullies and bowls. The conditions are unfavourable for backcountry touring.

Snowpack Structure

The rain will give rise as the day progresses to rapid moistening of the snowpack in some places below approximately 2600 m. This situation will give rise to a loss of strength within the snowpack especially on west, north and east facing slopes. Some fresh snow and in particular the mostly small wind slabs that are forming at high altitude will be deposited on the unfavourable surface of an old snowpack in particular on east to north to west facing aspects above approximately 2600 m.
