Mostly low danger - moist slides and continuing 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 accumulations require attentiveness. Naturally triggered small slides are possible, on steep grassy slopes isolated small-to-medium glide-snow avalanches.
The snowpack in the morning is well consolidated, softens later on. Small drifts are evident at high altitudes. The snowpack fundament is thoroughly wet up to high altitudes, can glide over smooth ground in all aspects. Below 1200-1400 m there is not much snow on the ground.
Nocturnal hours: skies will clear, the snowpack will have adequate outgoing longwave radiation. Monday: mostly sunny, high-altitude cirrus clouds but it will remain dry. At 2000 m: rising from -1 to +3 degrees. Light W/NW winds.
On Tuesday the weather will deteriorate, a cold front will bring fresh snowfall down to 1500 m. Winds will intensify, danger of dry-snow avalanches can increase. Danger of wet-snow avalanches will recede.
