Persistent weak layers
- Above 2,200 m
Weakly bonded old snow and wet snow require caution.
Weakly bonded old snow and wet snow require caution.
Weak layers in the old snowpack can be released in very isolated cases by individual winter sport participants, especially at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example, as well as in little used backcountry terrain. The avalanche prone locations are rare but are difficult to recognise. In isolated cases avalanches are medium-sized. In steep terrain there is a danger of falling on the hard snow surface. In the next few hours the weather will be cloudy. Below approximately 2000 m mostly small wet and gliding avalanches are possible as a consequence of the rain.
The snowpack will be quite well bonded. Faceted weak layers exist in the snowpack, especially on shady slopes above approximately 2200 m, and on sunny slopes at elevated altitudes. On Sunday the wind will be strong in the vicinity of peaks. Above approximately 2000 m snow will fall in some regions. The wind will transport only a little snow. Below approximately 2000 m: The surface of the snowpack is hardly frozen at all. Some rain will fall. The rain will give rise to significant softening of the snowpack.
The wind will be strong adjacent to ridgelines in some regions. Slight increase in danger of wet and gliding avalanches in the course of the day.
