Avalanche Activity

Fresh wind slabs represent the main danger.

The small quantity of fresh snow as well as the wind slabs formed during the snowfall are lying on the unfavourable surface of an old snowpack at intermediate and high altitudes. In isolated cases the avalanches are medium-sized and can be released by a single winter sport participant. The avalanche prone locations are to be found especially on steep southeast and south facing slopes and adjacent to ridgelines and in pass areas. The somewhat older wind slabs are in isolated cases deep and can be released by large loads in particular. Very steep grassy slopes: Gliding avalanches are still possible. In isolated cases Explanation: "these" may only stand for "these avalanches" are medium-sized. Backcountry touring and other off-piste activities call for meticulous route selection.

Snowpack Structure

The snowpack is fairly homogeneous; its surface is loosely bonded and consists of surface hoar and faceted crystals. 5 to 10 cm of snow, and even more in some localities, will fall until the early morning above approximately 1000 m. At intermediate and high altitudes there are 50 to 100 cm of snow. In particular at high altitude snow depths vary greatly, depending on the infuence of the wind. Sunday: From midday the weather will be mostly sunny.

Tendency

Monday: Gradual increase in danger of gliding avalanches and moist snow slides as a consequence of warming during the day and solar radiation.
