Wind slabs and weakly bonded old snow require caution.
Avalanches can in some places be released by a single winter sport participant and reach medium size. The avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain, especially on steep north and east facing slopes above the tree line, but in isolated cases also in areas close to the tree line. The prevalence of the avalanche prone locations will increase from midday. Avalanches can in isolated cases be released in the weakly bonded old snow in particular in shady places that are protected from the wind. Whumpfing sounds and shooting cracks when stepping on the snowpack can indicate the danger.
15 to 30 cm of snow, and up to 40 cm in some localities, has fallen since Sunday. 10 to 20 cm of snow will fall on Thursday. The wind will be strong at times. The fresh wind slabs are lying on soft layers. They are lying on surface hoar in some places. Faceted weak layers exist in the bottom section of the old snowpack in particular on west, north and east facing slopes.
Over a wide area 5 to 15 cm of snow, and even more in some localities, will fall. Wind slabs and weakly bonded old snow require caution.
