Fresh wind slabs at high altitude, especially above approximately 2500 m.

Fresh wind slabs at high altitude, especially above approximately 2500 m.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field. In particular along the border with France and along the border with Switzerland 2 to 10 cm of snow fell on Tuesday above approximately 2200 m. The wind was moderate to strong adjacent to ridgelines. Wind slabs are to be found especially adjacent to ridgelines and in gullies and bowls as well as at high altitudes and in the high Alpine regions. They are mostly small and can only be released in isolated cases. These avalanche prone locations are to be found on extremely steep slopes. Restraint should be exercised because avalanches can sweep people along and give rise to falls.

In all aspects snow depths vary greatly above approximately 2200 m, depending on the infuence of the wind. Below approximately 2000 m: A little snow is lying on south facing slopes. The snowpack is largely stable. It is not distinctly layered. Shady slopes: The snowpack consists of faceted crystals and has faceted crystals on the surface. Below approximately 2000 m: As a consequence of rain a crust formed on the surface. The new snow of yesterday is lying on a crust on sunny slopes.

In some localities increase in avalanche danger as a consequence of new snow and wind.
