Avalanche danger is low. Isolated danger zones occur on extremely steep shady slopes. Apart from the danger of being buried in snow masses, the risks of being forced to take a fall require consideration. On steep grassy slopes where there is sufficient snow on the ground, small glide-snow avalanches are possible.
The snowpack has settled well and has consolidated increasingly. On shady slopes the uppermost layers are still loose or soft, on sunny slopes a crust has often formed. On high mostly shady slopes, weak layers are evident inside the old snowpack, also at ground level, which avalanches can trigger down to lower layers with large additional loading. The older drifts at high altitudes are triggerable in isolated cases.
Nocturnal skies will be star-studded. On Monday it will be radiantly sunny, mild, with little wind. Zero-degree level at 2600m At 2000m: +2 - +1 to +4 degrees. Light W/NW winds at high altitudes.
Avalanche danger levels not expected to change significantly
