Fresh snow and snowdrifts often still prone to triggering
Nocturnal hours will be slightly foehn-impacted. In the latter part of the night, high-altitude clouds will move in. Thursday will be heavily clouded, the sun will generate only diffuse light. In the afternoon, the clouds will disperse. At 2000m: -7 to -2 degrees. Moderate S/SW winds.

Fresh snow and snowdrifts often still prone to triggering
Fresh snow and fresh snowdrift accumulations are often triggerable by large additional loading and then possibly growing to medium size. Danger zones occur particularly on steep shady slopes, behind protruberances in the landscape and in wind-loaded gullies and bowls. In isolated cases, slab avalanches can be triggered in extremely steep terrain in the old snow. At lower altitudes, loose-snow slides and on steep grass-covered slopes glide-snow avalanches are possible.
Fresh snow and drifts have been able to settle further. Especially on steep shaday slopes they are often poorly bonded with the soft layers of the old snowpack, and frequently the drifts have been blanketed by fresh snow. The old snowpack beneath it is well consolidated. At low altitudes the fresh snow fell on bare ground. On sunny slopes the fresh snow has already bonded well.
