Weakly bonded old snow requires caution. Slight increase in danger of moist avalanches in the course of the day.
Winter sport participants can release avalanches in isolated cases. These can reach large size. The avalanche prone locations for dry avalanches are to be found in particular on very steep northwest, north and northeast facing slopes above approximately 2000 m and on very steep west and east facing slopes above approximately 2200 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 the day progresses the likelihood of moist slab avalanches being released will increase on very steep west and east facing slopes below approximately 2200 m. Caution is to be exercised in particular in areas where the snow cover is rather shallow.
Snowpack
dp.7: snow-poor zones in snow-rich surrounding dp.10: springtime scenario
Distinct weak layers exist in the bottom section of the snowpack on west, north and east facing slopes, in particular above approximately 2000 m.
Towards its surface, the snowpack consists of faceted crystals, especially on shady slopes at elevated altitudes.
Outgoing longwave radiation during the night will be severely restricted. As a consequence of high relative humidity the snowpack can not consolidate, especially below approximately 2200 m.
In steep terrain there is a danger of falling on the hard snow surface. This applies at high altitude.

Weakly bonded old snow requires caution. Gradual increase in danger of wet avalanches in the course of the day.

Individual wet avalanches are possible. Weakly bonded old snow on northwest, north and northeast facing slopes.
As a consequence of the moist air individual moist and wet avalanches are possible, even medium-sized ones. These can be released by a single winter sport participant or triggered naturally. Caution is to be exercised in particular at the base of rock walls on very steep west and east facing slopes.
In very isolated cases dry avalanches can be released in the old snowpack and reach medium size, especially above approximately 1900 m on northwest, north and northeast facing slopes.

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.
Distinct weak layers exist in the old snowpack in particular on northeast, north and northwest facing slopes. This applies especially above approximately 1900 m.

Wet snow
The danger of wet avalanches will increase a little during the day.
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. The avalanche prone locations are rather rare. 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.
