Fresh wind slabs require caution.

Fresh wind slabs require caution.

The fresh wind slabs can in some places be released by a single winter sport participant. These are lying on the unfavourable surface of an old snowpack in particular on shady slopes above approximately 2200 m. They are to be avoided as far as possible. In isolated cases avalanches are medium-sized. The number and size of avalanche prone locations will increase with altitude. Caution is to be exercised in the vicinity of peaks, as well as adjacent to ridgelines. The avalanche prone locations are easy to recognise.

The sometimes storm force wind has transported the fresh and old snow, especially at elevated altitudes. The fresh wind slabs are in some cases prone to triggering. In some cases the wind slabs have bonded still only poorly with each other and the old snowpack, in particular on steep shady slopes and at high altitudes and in high Alpine regions. The snowpack will be generally subject to considerable local variations. Above the tree line snow depths vary greatly, depending on the infuence of the wind. On sunny slopes below approximately 2200 m only a little snow is now lying.

Outgoing longwave radiation during the night will be good over a wide area. On Saturday it will be exceptionally warm. The wind will be moderate over a wide area. As a consequence of mild temperatures the snow drift accumulations will stabilise during the next few days.
