Old snow, snow drifts
Avalanche prone locations
In all aspects above approximately 2400m.
Weak layers exist in the bottom section of the snowpack on shady slopes. This applies in particular above approximately 2800 m. Here avalanches can be released in deep layers of the snowpack and reach a dangerous size. The avalanche prone locations are rather rare but difficult to recognise. Caution is to be exercised in areas where the snow cover is rather shallow as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Careful route selection and spacing between individuals are recommended.
The sometimes strong wind has transported the old snow. The snow drift accumulations are to be found in all aspects. They are mostly small but can in some cases be released easily especially at their margins. The fresh snow drift accumulations are to be evaluated with care and prudence in steep terrain.
Below approximately 2500 m full-depth avalanches are possible.
