Old wind slabs are to be evaluated with care and prudence.

Old wind slabs are to be evaluated with care and prudence.

The various wind slabs of the last few days are in some cases still prone to triggering. They can be released by a single winter sport participant especially on steep shady slopes above approximately 2400 m. Caution is to be exercised in places that are protected from the wind, as well as in gullies and bowls, and behind abrupt changes in the terrain. The wind slabs are mostly easy to recognise. Avalanches can in isolated cases be released in the old snowpack also. Such avalanche prone locations are to be found in particular on steep shady slopes above approximately 2200 m and at transitions from a shallow to a deep snowpack. In the northwest and in the north these avalanche prone locations are more prevalent. Avalanches can reach medium size.

The somewhat older wind slabs are poorly bonded with the old snowpack especially on wind-protected shady slopes. They are in some cases prone to triggering. As a consequence of mild temperatures, solar radiation and the light to moderate wind, the snow drift accumulations stabilised during the last few days, in particular on sunny slopes. Here the snowpack is better bonded. The old snowpack will be prone to triggering in some places, especially on shady slopes between approximately 2200 and 2600 m.

As a consequence of the occasionally strong northerly wind, fresh snow drift accumulations will form on Saturday. In the regions exposed to the foehn wind there will be only a slight increase in the avalanche danger.
