Fresh wind slabs are to be evaluated with care and prudence. Avalanches can in isolated cases be released in the old snowpack.

As a consequence of new snow and a moderate to strong wind, sometimes avalanche prone wind slabs formed adjacent to ridgelines and in gullies and bowls. The avalanche prone locations are to be found on very steep north and east facing slopes above approximately 2000 m. They are covered with new snow in some cases and therefore difficult to recognise. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. Weak layers in the old snowpack can still be released in very isolated cases by winter sport participants in particular in little used terrain. Such avalanche prone locations are to be found in particular on extremely steep shady slopes at high altitudes and in high Alpine regions. Caution is to be exercised at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Avalanches can reach medium size.

The fresh wind slabs are lying on soft layers at high altitudes and in high Alpine regions. Faceted weak layers exist in the bottom section of the snowpack especially on west, north and east facing slopes. These can only be released in isolated cases. At elevated altitudes snow depths vary greatly, depending on the infuence of the wind. Only a small amount of snow is lying for the time of year.

Wind slabs and weakly bonded old snow require caution.
