Fresh snowfall will cover foehn-generated snowdrifts. Rain impact a burden below 2000 m.

Fresh snowfall will cover foehn-generated snowdrifts. Rain impact a burden below 2000 m.

Avalanche danger is moderate. In very steep terrain below 2000 m, naturally triggered medium-sized wet loose-snow avalanches are possible. In addition, on steep grass-covered slopes in all aspects which have not yet discharged, glide-snow avalanches can trigger at any time of day or night, in isolated cases grow to large size. Avoid zones below glide cracks. In few danger zones above 2400 m on sunny slopes there are weak layers in the uppermost part of the snowpack, triggerable by large additional loading, releases medium, occasionally large-sized. In moderately steep terrain, however, the powder atop a hardened snowpack base can be fully enjoyed.

Rain impact is burdening snowpack stability below 2000 m. Above that altitude the fresh snow will be deposited atop moistened old snow and in wind-exposed zones atop hard melt-freeze crusts. The snowpack is thoroughly wet up to 2000 m, on sunny slopes up to 2600 m, wet down to the ground. On shady slopes above 2000 m, the snowpack still has reserves of cold, thus, loose layers can still weaken the snowpack.

Tonight during the nocturnal hours the foehn will collapse. Clouds will become heavy and rainfall/snowfall (5-10 cm) is expected after midnight. It could rain up to 2000 m. On Sunday, heavily reduced visibility due to clouds and fog. Rainfall/snowfall esp. in the morning, snowfall level dropping to 1200 m at midday (5-10 cm expected). The W/NW winds will be moderate to strong (gusts at 30 km/hr). At 2000 m: -1 degree, at 3000 m: -8 degrees.

On Monday, gliding snow will remain the main problem. On sunny, extremely steep terrain, moderate naturally triggered loose-snow activity.
