Danger zones occur particularly in shady steep terrain where the snow is shallow and in transitions from shallow to deep snow. Small to medium-sized avalanches are easily possible by large additional loading. On steep grassy slopes, and on sunny slopes in general, but increasingly frequently also on shady slopes, small-to-medium glide-snow avalanches are possible. Caution urged below glide cracks
The snowpack has settled well and consolidated increasingly. On shady slopes the uppermost layers are still loose or soft, on sunny slopes a crust has often formed which softens during the daytime. On high mostly shady slopes near ridgelines, older snowpack accumulations require attentiveness. In addition, weak layers are evident inside the old snowpack at high altitudes, also at ground level, which avalanches can trigger down to.
Nocturnal skies will be star-studded. On Tuesday it will be radiantly sunny, mild, with little wind. Zero-degree level at 2500m At 2000m: +1 to +4 degrees. Light westerly winds at high altitudes.
Avalanche danger levels will continue to decrease. Glide-snow avalanches continue to be possible.
