Persistent weak layers
- Above 2,200 m
Caution: weak layers in the old snow
Caution: weak layers in the old snow
Weak layers can be triggered in the old snow even by one sole skier. Such danger zones lie on N/W/E facing 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. Due to snowpack moistening, isolated moist loose-snow avalanches are possible, esp. on very steep slopes, small releases.
Some rainfall, and some snowfall, esp. at high altitudes. Nocturnal outgoing longwave radiation is nearly absent. The snowpack is moist, esp. below 2500m. In the middle part of the snowpack on N/W/E facing slopes there are faceted, expansively metamorphosed weak layers evident, esp. above 2200m.
Due to a foehn-driven SW air current, dense clouds will accumulate on Saturday, the summits often be shrouded in fog. During the course of the day, light precipitation. Moderate to strong SW winds, gusts reaching 60 km/hr. At 1000m: +6 degrees; at 2000m: 0 degrees; at 3000m: -4 degrees. Source: GeoSphere
