Points saillants

Weak layers in the old snowpack represent the main danger. Wind slabs require caution.

Tendency

Weak layers in the old snowpack represent the main danger. As a consequence of warming during the day and the solar radiation, the likelihood of wet snow slides being released will increase a little in particular on extremely steep sunny slopes.

Avalanche Activity

Weak layers in the old snowpack represent the main danger. Wind slabs require caution.

Weak layers in the old snowpack can still be released in some places by individual winter sport participants. Such avalanche prone locations are to be found especially on very steep north facing slopes above approximately 2200 m, in isolated cases also on very steep east and west facing slopes above approximately 2500 m. The avalanche prone locations are barely recognisable, even to the trained eye. The current avalanche situation calls for meticulous route selection. Avalanches can reach medium size. Wind slabs can be released by a single winter sport participant in isolated cases on very steep shady slopes above approximately 2400 m, especially adjacent to ridgelines. The mostly small wind slabs are clearly recognisable to the trained eye. As a consequence of warming during the day and the solar radiation, the likelihood of moist loose snow slides being released will increase a little on extremely steep south facing slopes.

Snowpack Structure

Shady slopes: Avalanche prone weak layers exist in the centre of the snowpack in particular on west, north and east facing slopes. As a consequence of a moderate wind, mostly small wind slabs formed since Monday adjacent to ridgelines. These are lying on soft layers at elevated altitudes. Sunny slopes: The snowpack will be in most cases well bonded. As a consequence of low temperatures and low relative humidity a crust will form on the surface during the course of the night. The solar radiation will give rise as the day progresses to increasing softening of the snowpack on steep sunny slopes. Below the tree line only a little snow is now lying.
