Points saillants

Outgoing longwave radiation during the night will be good in some case. In the afternoon as a consequence of warming during the day and solar radiation there will be only a slight increase in the danger of moist and wet avalanches.

Problèmes avalancheux

  • Wind slab

    • Above 2,500 m
  • Wet snow

    • Below 2,700 m

Avalanche Activity

Outgoing longwave radiation during the night will be good in some case. In the afternoon as a consequence of warming during the day and solar radiation there will be only a slight increase in the danger of moist and wet avalanches.

The fresh and older wind slabs remain in some cases prone to triggering in particular on very steep shady slopes above approximately 2500 m. The more recent wind slabs are mostly small. They can be released in isolated cases. This applies in particular adjacent to ridgelines and in pass areas. The wind slabs are clearly recognisable to the trained eye. As a consequence of warming during the day, the likelihood of wet avalanches during the day being released will increase gradually. Mostly small moist and wet avalanches are possible. This applies in particular in steep rocky terrain.

Snowpack Structure

At high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind. Individual weak layers exist in the snowpack on shady slopes. In particular in shady places that are protected from the wind above approximately 2200 m: Towards its surface, the snowpack is soft; its surface consists of loosely bonded snow.

Tendency

The avalanche danger will persist.
