Mostly low danger - isolated glide-snow avalanches
Mostly low avalanche danger prevails. Danger zones occur mostly in shady extremely steep terrain. Isolated small slab avalanches are possible by large additional loading. At high altitudes small snowdrift accumjulations require attentiveness. In rocky steep terrain in case of solar radiation, loose-snow slides are possible on steep grass-covered slopes (small-to-medium avalanches).
The below-average depth snowpack is well consolidated and softens only slowly during thd daytime hours. The fundament is thorougly wet up to high altitudes, can glide over smooth ground in all aspects. Below 1500 m there is not much snow on the ground.
Nocturnal hours: skies will be clear or with only scattered clouds, longwave outgoing radiation will be adequate. Thursday: initially sunshine, cloudbanks will later on move in from the west, also some convective cloud build-up. Slightly warmer. At 2000 m: -11 to -4 degrees. Light to moderate westerly winds.
Friday will be cloudy, instable, with minor snowfall and rain showers. Snowfall level will lie between 1000 and 1500 m. Winds will be light. Avalanche danger levels are not expected to change significantly.
