Stability: poor · Frequency: few
Fresh wind slabs require caution.
As a consequence of snowfall and the strong wind, fresh snow drift accumulations formed. The avalanche danger will persist. Fresh wind slabs must be evaluated with care and prudence on steep shady slopes above approximately 2400 m. A certain danger of gliding avalanches exists. This applies in the regions with a lot of snow on steep east, south and west facing slopes below approximately 2600 m. Caution is to be exercised in areas with glide cracks. In steep terrain there is a danger of falling on the hard snow surface.
Over a wide area 10 to 20 cm of snow, and even more in some localities, has fallen above approximately 1000 m. As a consequence of new snow and a strong wind, sometimes avalanche prone wind slabs formed in the course of the day adjacent to ridgelines and in gullies and bowls. Towards its base, the snowpack is faceted. Snow depths vary greatly above the tree line, depending on the infuence of the wind. Low and intermediate altitudes: The snowpack is wet all the way through and its surface has a melt-freeze crust that is strong in many cases, this also applies on steep sunny slopes at high altitude.
