Avalanches can in some cases be released in the old snowpack and reach large size in isolated cases 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. As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase a little also on steep sunny slopes at elevated altitudes.
Only isolated mostly small wet loose snow avalanches are possible.
Snowpack
dp.7: snow-poor zones in snow-rich surrounding dp.10: springtime scenario
Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. This applies especially above approximately 2000 m.
Towards its surface, the snowpack consists of faceted crystals, especially on shady slopes.
Outgoing longwave radiation during the night will be quite good. The surface of the snowpack will freeze to form a strong crust. The weather conditions as the day progresses will give rise to slight 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.
Danger level
1900m

Persistent weak layer

Individual avalanche prone locations are to be found in particular on northwest to north to northeast facing aspects.
In very isolated cases avalanches can be released in the old snowpack and reach medium size. This applies even in case of a single winter sport participant in isolated cases, especially above approximately 1900 m on northwest, north and northeast facing slopes.
Individual mostly small wet avalanches are possible. Many starting zones have released the snow.
Snowpack
dp.1: deep persistent weak layer dp.10: springtime scenario
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 was good over a wide area. Towards its surface, the snowpack consists of faceted crystals, especially in areas where the snow cover is rather shallow on shady slopes.
Outgoing longwave radiation during the night will be quite good at times. 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.
Danger level
Low avalanche danger will prevail.
Avalanches are no longer likely to occur. Very isolated avalanche prone locations are to be found on very steep shady slopes at elevated altitudes.
