Persistent weak layers
- Above 1,900 m
Caution: weak layers in old snowpack ca trigger in isolated cases
Caution: weak layers in old snowpack ca 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 1900m. 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 above 1900m: inside the snowpack are faceted expansively metamorphosed weak layers. 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.
Saturday will begin with radiant sunshine in the mountains of Carinthia. Later in the day, clouds will move in from the southwest, hamper the sunshine, but summits will remain in the clear until evening. A moderate SW wind will be blowing. At 2000m: rising from -5 to -2 degrees in the evening; at 3000m: -7 degrees. Source: GeoSphere Austria.
Weak layers in the old snowpack demand caution
