In sintesi

Weakly bonded old snow and wet snow represent the main danger.

Problemi valanghivi

  • Persistent weak layers

    • Above 2,100 m
  • Wet snow

    • Above 1,800 m

Snowpack Structure

The sometimes strong wind has transported the loosely bonded old snow. Field observations and stability tests confirm the existence of a weak snowack on shady slopes. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack on very steep sunny slopes. In all regions less snow than usual is lying. At intermediate and high altitudes there are 50 to 70 cm of snow, and even more in some localities. At high altitude snow depths vary greatly, depending on the infuence of the wind.

Tendency

The danger of dry and moist avalanches will persist.

Avalanche Activity

Weakly bonded old snow and wet snow represent the main danger.

Fresh and older wind slabs can be released by a single winter sport participant in isolated cases on very steep northeast, north and northwest facing slopes. The avalanches are rather small. Also in places that are protected from the wind and shady slopes: The old snowpack is faceted and weak. This snow can be released by a single winter sport participant in isolated cases on extremely steep northeast, north and northwest facing slopes. Here the avalanches are only shallow. On very steep sunny slopes moist snow slides and avalanches are possible from midday, but they will be mostly small.
