Persistent weak layers
- Above 2,000 m
Caution: weak layers in old snowpack can trigger in isolated cases
Caution: weak layers in old snowpack can trigger in isolated cases
Avalanches can be triggered in the weak layers by one sole skier in some places, and grow to medium size. Danger zones occur mostly in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls, a on very steep shady slopes above 2000m. Attention must be given to the dangers of being swept along and forced to take a fall.
The snowpack is highly diverse over small areas. Below 1600m there is little snow on the ground. Shady slopes: the uppermost part of the snowpack is expansively metamorphosed, there is surface hoar and also faceted crystals. In the lower part of the snowpack there are faceted expansively metamorphosed crystals evident. Sunny slopes: snowpack largely stable, with a crust on the surface.
On Monday skies will become increasingly gray, a compact high-fog like cloud cover will spread throughout Carinthia during the course of the day (upper border at 1500-2000m, so that only intermediate and high-alpine regions will get sunshine). Winds will be light to moderate from the southwest. At 2000m: -3 degrees; at 3000m: -8 degrees. Source: GeoSphere Austria
Weak layers in the old snowpack demand caution
