Heed: wet-snow avalanches, fresh snow and snowdrifts at high altitudes

Avalanche danger is considerable. Due to higher daytime temperatures and rain impact, increasingly frequent naturally triggered wet slides and avalanches are possible in zones which have not yet discharged. Avalanches can be triggered by winter sports enthusiasts, even fracture down to more deeply embedded layers inside the snowpack and thereby grow to larger size. On steep grassy slopes, glide-snow avalanches still threaten. Isolated small-to-medium avalanches can still be triggered in extremely steep terrain.

There has been up to 20-40 cm of fresh snow registered in high alpine regions. As a result of wind impact, fresh snowdrift accumulations were generated with increasing altitude over the last few days which can now stabilize due to warmth and solar radiation. The moist old snowpack surface is well consolidated. Due to the lack of nocturnal outgoing radiation it cannot freeze over and thus, softens quickly in the daytime. Isolated weak layers are possible trigger-sensitive on steep shady slopes. At low and intermediate altitudes the ground is often bare of snow, esp. on sunny slopes. Avalanche Warning Services no longer have as much information from these regions.

Nocturnal hours: dispersed clouds, hardly any outgoing longwave radiation. Sunday: adequate conditions, possibly reduced visibility, brief showers in the afternoon, snowfall level at 2400 m. At 2000 m: 0-6 degrees, light winds.

On Monday, heavily overcast skies, rainy during the afternoon. snowfall level descending from 2400 to 2000 m. Due to lack of nocturnal outgoing radiation the snowpack cannot freeze, making wet-snow avalanches the main danger.
