Fresh wind slabs represent the main danger. Gliding snow requires caution. Wet loose snow avalanches are possible in the afternoon.
The fresh snow and the sometimes large wind slabs can be released by a single winter sport participant in particular on steep shady slopes above the tree line. This applies especially adjacent to ridgelines. The avalanche danger will increase during the day. The number and size of avalanche prone locations will increase with altitude. The avalanche prone locations are difficult to recognise. Avalanches can in isolated cases reach large size. Weak layers in the old snowpack can still be released in very isolated cases by individual winter sport participants. Avalanche prone locations are to be found in particular on very steep west and east facing slopes above approximately 2400 m. Avalanche prone locations are to be found also on very steep north facing slopes above approximately 2100 m. Avalanches can in isolated cases penetrate deep layers and reach large size. As a consequence of the new snow loose snow avalanches are possible, even medium-sized ones. In addition an appreciable danger of gliding avalanches exists, especially on grassy slopes below approximately 2600 m, as well as on steep shady slopes below approximately 2400 m. These can reach dangerously large size. Areas with glide cracks are to be avoided.
In some regions up to 30 cm of snow, and even more in some localities, has fallen since Saturday above approximately 1500 m. Over a wide area up to 20 cm of snow, and even more in some localities, will fall above approximately 1200 m. As a consequence of new snow and strong wind the wind slabs have increased in size. Fresh and somewhat older wind slabs are lying on soft layers in particular on shady slopes. They are in some cases prone to triggering. This applies above the tree line. Isolated avalanche prone weak layers exist deeper in the snowpack in particular on steep east, north and west facing slopes. In very isolated cases new snow and wind slabs are lying on a weakly bonded old snowpack.
Over a wide area 20 to 40 cm of snow, and even more in some localities, will fall until Wednesday. As a consequence of new snow and strong wind the wind slabs will increase in size. Numerous small and medium-sized loose snow avalanches are to be expected. The fresh snow and the sometimes large wind slabs represent the main danger. Gliding avalanches require caution.
