Distinct weak layers in the old snowpack are treacherous. Fresh wind slabs are to be evaluated with care and prudence.

Distinct weak layers in the old snowpack are treacherous. Fresh wind slabs are to be evaluated with care and prudence.

Distinct weak layers in the old snowpack can still be released by individual winter sport participants in particular on west, north and east facing slopes. This applies in particular in particular above the tree line, and below approximately 2600 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 large size. As a consequence of a strong wind, sometimes easily released wind slabs formed in the last few days. The clearly visible wind slabs are in some cases still prone to triggering in particular on northwest to north to east facing aspects. These are to be bypassed as far as possible. The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2200 m. In addition a latent danger of gliding avalanches exists.

Faceted weak layers exist in the centre of the snowpack, especially on west, north and east facing slopes above the tree line, and below approximately 2600 m. The strong wind has transported the fresh and old snow. The fresh and older wind slabs are poorly bonded with the old snowpack in particular on shady slopes and generally at elevated altitudes. The rain gave rise on Thursday to significant moistening of the snowpack over a wide area below approximately 2400 m. As a consequence of falling temperatures a crust formed on the surface.

On Monday as a consequence of new snow and strong wind there will be an increase in the avalanche danger.
