Wet-snow avalanches due to higher daytime temperatures

Wet-snow avalanches due to higher daytime temperatures

Due to warmth and 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: scattered clouds in the early part of the night, denser clouds will move in later bringing rainfall in early morning, possibly intensive in the northern regions. Snowfall level just below 2000 m and ascending. Mostly dry in Montafon. Friday: most of the peaks hidden in fog, plus rainfall between Bregenzerwald and Lechtal Alps, less further south. Snowfall level will lie at 2400 m. At 2000 m: 4 degrees. Strong westerly winds.

Probably rain showers on Saturday morning, but clouds will soon disperse, in the afternoon largely dry and quite sunny with convective cloud build-up and high-altitude clouds from the south. It will remain warm. Due to lack of nocturnal outgoing radiation, the snowpack can hardly freeze, thus, wet-snow avalanches continue to be likely.
