Slightly rising danger of moist/wet avalanches due to rainfall. Caution: weak layers in old snow.
Due to rainfall, increasingly frequent moist/wet-snow avalanches are possible, esp. below 2000m, on very steep slopes in all aspects. Releases are relatively small and can be triggered in the old snow even by one sole skier. Such danger zones lie on very steep shady slopes and in transitions into gullies and bowls above 2000m and can reach medium size.
Snowpack
dp.3: rain dp.1: deep persistent weak layer
Some rainfall below 2000m, and some snowfall, esp. at high altitudes. Nocturnal outgoing longwave radiation is nearly absent. The snowpack is moist. In the lowermost part of the snowpack there are faceted, expansively metamorphosed weak layers evident, esp. above 2000.

Caution: weak layers in the old snow
Weak layers can be triggered in the old snow even by one sole skier. Such danger zones lie on N/W/E facing very steep shady slopes and in transitions into gullies and bowls above 2200m. Very isolated danger zones also occur on very steep sunny slopes above 2600m. Avalanches can in isolated cases reach medium size. Due to snowpack moistening, isolated moist loose-snow avalanches are possible, esp. on very steep slopes, small releases.

Some rainfall, and some snowfall, esp. at high altitudes. Nocturnal outgoing longwave radiation is nearly absent. The snowpack is moist, esp. below 2500m. In the middle part of the snowpack on N/W/E facing slopes there are faceted, expansively metamorphosed weak layers evident, esp. above 2200m.
