Avalanches can be released in near-ground layers and reach large size in isolated cases. The avalanche prone locations are to be found in particular on very steep west, north and east facing slopes above approximately 2000 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Fresh wind slabs are in some cases prone to triggering on near-ridge shady slopes. Single winter sport participants can release avalanches easily, including medium-sized ones. In addition small and, in isolated cases, medium-sized moist loose snow avalanches are possible, in the event of solar radiation in particular on extremely steep slopes.
20 to 30 cm of snow has fallen since Sunday. The moderate wind has transported some snow. Fresh wind slabs are to be found in particular adjacent to ridgelines and in pass areas. They are lying on the unfavourable surface of an old snowpack on shady slopes. Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. This applies above approximately 2000 m. Below approximately 2000 m and steep sunny slopes: The old snowpack will be moist.
Fresh wind slabs require caution. Weakly bonded old snow requires caution.
