Light (moderate in exposed terrain) SW winds, 30 km/hr. At 1000m: +12 degrees; at 2000m: 3 degrees; at 3000m: -3 degrees. Source: GeoSphere Caution urged towards weak layers in old snow Avalanches can be triggered in the old snow even by one sole skier on shady slopes above 2200m, mostly medium-sized releases. Such danger zones lie on very steep shady slopes and in transitions into gullies and bowls above 2200m. Very isolated danger zones also occur on very steep sunny slopes above 2600m. Avalanches can in isolated cases reach medium size. Small snowdrifts can trigger on very steep shady slopes at high altitudes and in high-alpine terrain. Danger zones occur seldom. Due to daytime warmth and solar radiation, moist loose-snow avalanches are possible but mostly small-sized, esp. triggerable on extremely steep sunny slopes. Clear skies widespread. Due to low temperatures and low air moisture, near-surface crusts form above 2400m. In the lowermost part of the snowpack there are faceted, expansively metamorphosed weak layers evident, esp. above 2200m. Fresh snowdrift accumulations are being deposited atop soft layers . On sunny slopes, the snowpack softens during the day on extremely steep slopes.

Wet loose-snow avalanches possible on very steep sunny slopes. Avalanches can be triggered in the old snow even by one sole skier on shady slopes above 2000m, mostly medium-sized releases. Freshly generated snowdrift accumulations can be triggered by one sole skier, esp. on shady slopes. Caution urged at the foot of rock walls and behind protruberances in the terrain, and in gullies and bowls. Due to daytime warming and solar radiaation, moist loose-snow avalanches are possible, mostly small releases on very steep sunny slopes. Clear skies widespread. Due to low temperatures and low air moisture, near-surface crusts form above 2400m. In the lowermost part of the snowpack there are faceted, expansively metamorphosed weak layers evident, esp. above 2200m. Fresh snowdrift accumulations are being deposited atop soft layers .
