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 be released in the old snowpack and reach quite a large size on very steep northwest, north and northeast facing slopes. As a consequence of warming during the day and solar radiation small and, in isolated cases, medium-sized moist loose snow avalanches are possible.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Very steep, little used shady slopes: Avalanche prone weak layers exist in the old snowpack in particular on northwest, north and northeast facing slopes. This applies at high altitude.
Outgoing longwave radiation during the night will be good in some case. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack.
Tendency
Fresh wind slabs are in some cases still prone to triggering in particular on steep shady slopes. The avalanche danger will decrease gradually.

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.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
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.
Tendency
Fresh wind slabs are in some cases still prone to triggering in particular on steep shady slopes. The avalanche danger will decrease gradually.
