Weakly bonded old snow requires caution.
Avalanches can in some cases be released in the old snowpack and reach quite a large size on west, north and east facing slopes. This applies even in case of a single winter sport participant in some cases. The avalanche prone locations are to be found in particular 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.
Individual mostly small wet avalanches are possible below approximately 2600 m.
Snowpack
dp.1: deep persistent weak layer
dp.10: springtime scenario
Shady slopes: Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. This applies especially above approximately 2000 m.
Outgoing longwave radiation during the night will be good. The surface of the snowpack will freeze to form a strong crust. The weather conditions as the day progresses will give rise to softening of the snowpack in particular on very steep sunny slopes.
Tendency
Weakly bonded old snow requires caution. Slight increase in danger of wet avalanches as a consequence of warming during the day and solar radiation.
