Rising danger of moist/wet avalanches due to rainfall. Attention: weak layers in old snow.

Due to rainfall, increasingly frequent moist/wet-snow avalanches are possible, esp. on steep slopes in all aspects below 2000m. 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 1900m on steep N/W/E facing slopes and in gullies and bowls and can reach medium size.

More rainfall was registered than expected, but more is still expected, along with 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.

Isolated showers in early morning, later slackening off, then the clouds will disperse and sunny intervals are expected. In the afternoon, local showers again expected. Moderate SW winds. At 2000m: +1 degree. Source: GeoSphere
