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).
A bit of fresh snow deposited atop a stable, below-average snowpack, well consolidated in the morning, softening later in the day amid intense solar radiation. The snowpack fundament is thoroughly 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: clouds will become dense in the evening, light snowfall/rainfall can be expected as of midnight (snow above 1000 m). Friday: adequate visibility and a few windows of sunshine until after midday, then clouds will move in, the peaks will become shrouded in fog, snow showers will become more frequent. Only minor amounts. At 2000 m: -8 to -4 degrees. Light winds from varying directions.
Saturday will bring April weather: showers over the daytime hours, snowfall from 1000-1500m. Winds will be light. Avalanche danger levels are not expected to change significantly.
