Persistent weak layers
- Above 2,200 m
Caution: weak layers in the old snow, fresh snowdrifts at high and high-alpine altitudes
Caution: weak layers in the old snow, fresh snowdrifts at high and high-alpine altitudes
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. In addition, fresh snowdrift accumulations require attentiveness, esp at high and high-alpine altitudes. Due to snowpack moistening, isolated moist loose-snow avalanches are possible, esp. on very steep slopes, small releases.
Up to 10cm fresh snow expected regionally, locally more, esp at high altitudes. In the middle part of the snowpack on N/W/E facing slopes there are faceted weak layers, esp above 2200m. Due to fresh snowfall and moderate-to-strong velocity southerly winds, small snowdrift accumulations will be generated esp. in ridgeline terrain. Nocturnal outgoing longwave radiation hardly exists, which leads to increasing moistening of the snowpack esp. below 2200m.
On Sunday, dense clouds will accumulate due to strong-velocity SW winds, gusts reaching 80 km/hr. In afternoon, precipitation will taper off in the southern regions. At 2000m: +1 degree. Source: GeoSphere
