As a consequence of the strong to storm force southerly foehn wind, fresh snow drift accumulations will form. In some cases the various wind slabs have bonded poorly with each other and the old snowpack. They can be released easily especially at their margins. The wind slabs of the last two days are lying on surface hoar in some places in areas close to the tree line. In addition further wind slabs formed adjacent to ridgelines in all aspects and generally in the high Alpine regions. Reports filed by observers and stability tests confirm that the stability of the snowpack varies greatly within a small area on wind-loaded slopes.

A great many avalanches have been released as a consequence of the new snow.
The new snow represents the main danger.
Avalanches can be released by a single winter sport participant and reach very large size.
Snowpack
Over a wide area 50 cm of snow, and up to 70 cm in some localities, will fall until the early morning above approximately 1800 m. The new snow can be released easily or naturally in all aspects above the tree line. Snow profiles and stability tests have confirmed the distinct danger. The covering of new snow is soft. Distinct weak layers in the upper part of the snowpack are difficult to recognise. The new snow will be deposited on surface hoar in areas close to the tree line. Above the tree line: Towards its base, the snowpack is faceted and weak. Over a wide area new snow is lying on a weakly bonded old snowpack. Avalanches can be released in deeper layers very easily.
