In sintesi

The current avalanche situation calls for experience in the assessment of avalanche danger and careful route selection. In the regions exposed to a lot of new snow caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls.

Avalanche Activity

The current avalanche situation calls for experience in the assessment of avalanche danger and careful route selection. In the regions exposed to a lot of new snow caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls.

The large quantity of fresh snow of the weekend and in particular the wind slabs formed by the light to moderate southeasterly wind can be released easily, or, in isolated cases naturally above approximately 2100 m. The new snow and wind slabs of Tuesday are poorly bonded with the old snowpack in some places in particular on steep shady slopes above approximately 2000 m. On very steep slopes the avalanches can be triggered in the various layers of new snow and reach large size. Avalanches can be released, even by small loads in isolated cases, in particular in gullies and bowls, and behind abrupt changes in the terrain. Whumpfing sounds and natural avalanches serve as an alarm sign. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection.

Snowpack Structure

Over a wide area over a wide area 25 to 50 cm of snow, and even more in some localities, has fallen since Friday above approximately 1800 m. 2 to 5 cm of snow fell on Tuesday above approximately 1000 m. Adjacent to ridgelines and in gullies and bowls soft wind slabs formed. New snow and wind slabs are lying on a weakly bonded old snowpack, in particular on shady slopes. Sunshine and high temperatures gave rise on Monday to significant consolidation of the snowpack over a wide area on sunny slopes below approximately 2500 m.

Tendency

The weather will be cold. The avalanche danger will persist.
