Heed: wet-snow avalanches and snowdrifts at high altitudes
Avalanche danger is considerable. Due to higher daytime temperatures 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. Isolated small-to-medium avalanches can still be triggered in extremely steep terrain.
There has been up to 20-40 cm of fresh snow registered in high alpine regions. As a result of wind impact, fresh snowdrift accumulations were generated with increasing altitude over the last few days which can now stabilize due to warmth and solar radiation. The moist old snowpack surface is well consolidated. Due to the lack of nocturnal outgoing radiation it cannot freeze over and thus, softens quickly in the daytime. Isolated weak layers are possible trigger-sensitive on steep shady slopes. At low and intermediate altitudes the ground is often bare of snow, esp. on sunny slopes. Avalanche Warning Services no longer have as much information from these regions.
Nocturnal hours: in the early part of the night, intensive showers from the north, some thunderstorms. Later it will taper off, clouds disperse somewhat. Saturday: mixed conditions, including brief rain showers, snowfall above 2400 m. At 2000 m: 1-6 degrees. Moderate to brisk westerly winds.
Intermittent sunshine, a bit of convective cloud build-up, pleasant conditions, showers possible in the southern regions, snowfall above 2400 m. Due to lack of outgoing nocturnal radiation the snowpack cannot freeze, making wet-snow avalanches to be expected. Caution: snowdrifts in high alpine regions.
