Thoroughly wet snowpack and wet-snow avalanches

Thoroughly wet snowpack and wet-snow avalanches

Due to rain impact, increasingly frequent naturally triggered wet slides and avalanches are possible in zones which have not yet discharged. On steep grassy slopes, glide-snow avalanches still threaten.

The shallow old snowpack is being weakened by rainfall and lack of nocturnal outgoing radiation, it softens up further during the daytime. All in all, there is not much snow on the ground. 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 possible.
