Weak layers in the old snowpack can be released in very isolated cases.
Weak layers in the old snowpack can be released in very isolated cases in shady places that are protected from the wind. The avalanche prone locations are to be found on very steep west, north and east facing slopes above approximately 2400 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Avalanches can reach medium size in isolated cases. The fresh wind slabs can in very isolated cases be released, even by a single winter sport participant, but they will be small in most cases. Avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain at elevated altitudes. They are easy to recognise.
The small wind slabs are lying on soft layers in particular on steep shady slopes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The snowpack will be moist at low and intermediate altitudes.
A generally favourable avalanche situation will prevail.
