In sintesi

As a consequence of the northwesterly wind the avalanche prone locations will become more prevalent in the late morning. At elevated altitudes a considerable avalanche danger will prevail.

Tendency

The weather will be sunny at times. These conditions will facilitate a gradual settling of the snowpack.

Avalanche Activity

As a consequence of the northwesterly wind the avalanche prone locations will become more prevalent in the late morning. At elevated altitudes a considerable avalanche danger will prevail.

As a consequence of snowfall and the moderate to strong wind, fresh snow drift accumulations formed. These can in some places be released by a single winter sport participant and reach large size. This applies in particular on steep slopes also in areas close to the tree line, as well as in gullies and bowls, and behind abrupt changes in the terrain at intermediate and high altitudes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches are a clear indication of a weakly bonded snowpack. As a consequence of warming during the day and solar radiation more medium-sized and, in isolated cases, large avalanches are possible. Ski touring and other off-piste activities, including snowshoe hiking, call for experience in the assessment of avalanche danger. Careful route selection and spacing between individuals are recommended.

Snowpack Structure

10 to 25 cm of snow fell on Wednesday above approximately 1500 m. As a consequence of new snow and a moderate to strong wind from southerly directions, precarious wind slabs formed. The new snow and wind slabs are lying on soft layers in particular on wind-protected shady slopes. Intermediate and high altitudes: Isolated avalanche prone weak layers exist in the bottom section of the snowpack in particular on very steep shady slopes. Especially steep sunny slopes: As a consequence of rising temperatures and solar radiation a crust will form on the surface during the next few days.
