Winter sport participants can release avalanches in isolated cases. These can reach large size in isolated cases. The avalanche prone locations are to be found in particular on very steep west, north and east facing slopes above approximately 2000 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.
As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase a little in particular on very steep west and east facing slopes below approximately 2200 m.
Snowpack
dp.7: snow-poor zones in snow-rich surrounding
Above approximately 2000 m: Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Towards its surface, the snowpack consists of faceted crystals, especially on shady slopes. In steep terrain there is a danger of falling on the hard snow surface.
Below approximately 2000 m: The old snowpack will be moist.
Tendency
Weakly bonded old snow requires caution.
Danger level
1900m
Avalanche Problem
Persistent weak layer
1900m
Weakly bonded old snow on northwest, north and northeast facing slopes.
Dry avalanches can be released, even by small loads in isolated cases and reach medium size. This applies especially above approximately 1900 m on northwest, north and northeast facing slopes. The avalanche prone locations are rare.
As a consequence of warming during the day and solar radiation individual moist and wet avalanches are possible, but they will be mostly small. Caution is to be exercised in particular at the base of rock walls on very steep west and east facing slopes. Many starting zones have released the snow.

dp.10: springtime scenario dp.1: deep persistent weak layer
Distinct weak layers exist in the old snowpack in particular on northeast, north and northwest facing slopes. This applies especially above approximately 1900 m.
Outgoing longwave radiation during the night will be reduced. The weather conditions will give rise to increasing and thorough wetting of the snowpack especially on very steep sunny slopes.
Tendency
Weakly bonded old snow requires caution.
Danger level
Low avalanche danger will prevail.
In very isolated cases dry avalanches can be released in the old snowpack. This applies on northwest, north and northeast facing slopes in the vicinity of peaks. The avalanche prone locations are very rare. As a consequence of warming, the likelihood of moist and wet avalanches being released will increase a little in particular on west and east facing slopes. These can be released by people, but they will be small in most cases.
