Persistent weak layers
- Above 2,000 m
Isolated danger zones. Wet loose-snow avalanches possible on very steep sunny slopes.
Isolated danger zones. 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. Due to daytime warming and solar radiaation, moist loose-snow avalanches are possible, mostly small releases on very steep sunny slopes. On very steep grass-covered slopes glide-snow avalanches are possible, mostly small sized releases, esp. on very steep sunny slopes.
Since Friday, 20-30cm of fresh snow has been registered above 1800m, locally more. High air moisture has moistened the snowpack esp. above 2400m. Heavily clouded skies mean the snowpack cannot firm up during the nocturnal hours. More deeply embedded inside the snowpack on shady slopes are faceted, expansively metamorphosed weak layers, esp. above 2000m. Fresh snowdrift accumulations have been deposited atop soft layers esp. above 2000m.
On Tuesday, high-pressure front conditions will continue with brilliant sunshine, mostly cloudless skies and outstanding visibility. Winds will start with speeds of 50 km/hr then slacken off to 24-40 km/hr. At 1000m: +1 degree; at 2000m: -8 degrees; at 3000m: -12 degrees. Source: GeoSphere
Low temperatures and low air moisture will lead to a gradual stabilization of the snowpack
