Wind slabs and weakly bonded old snow require caution.
The fresh and older wind slabs can be released easily, even by a single winter sport participant, in particular on northwest to north to northeast facing aspects above approximately 2000 m. Avalanches can in isolated cases release deeper layers of the snowpack and reach large size. Weakly bonded old snow requires caution. These avalanche prone locations are to be found in particular in northwest to north to northeast facing aspects. Caution is to be exercised in particular on steep shady slopes, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. As a consequence of warming during the day and solar radiation small and medium-sized natural avalanches are possible.
Over a wide area 30 to 50 cm of snow, and even more in some localities, fell in the last two days above approximately 1700 m. Distinct weak layers exist in the bottom section of the snowpack in particular on steep shady slopes. This applies especially above approximately 2000 m. Below approximately 1800 m: The old snowpack remains moist.
Fresh wind slabs are in some cases still prone to triggering in particular on steep shady slopes. The avalanche danger will decrease gradually.
