Wind slabs above approximately 2300 m.

Wind slabs above approximately 2300 m.

The wind slabs of the last few days can be released by a single winter sport participant in isolated cases above approximately 2300 m. They are to be found in particular adjacent to ridgelines and in gullies and bowls, caution is to be exercised at transitions from a shallow to a deep snowpack. Apart from the danger of being buried, restraint should be exercised in view of the danger of avalanches sweeping people along and giving rise to falls.

The wind has transported the new snow and, in some cases, old snow as well. In some cases the wind slabs have bonded still only poorly with the old snowpack. In high Alpine regions snow depths vary greatly, depending on the infuence of the wind. Below approximately 2000 m from a snow sport perspective, in most cases insufficient snow is lying.

The weather conditions will foster a gradual strengthening of the snow drift accumulations.
