Slight increase in danger of wet avalanches in the course of the day.
As the day progresses as a consequence of warming during the day and solar radiation there will be only a slight increase in the danger of wet avalanches. Wet avalanches can in isolated cases be released by a single winter sport participant. This applies on very steep shady slopes below approximately 2500 m, as well as on very steep sunny slopes at elevated altitudes.
Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2500 m. Especially transitions from a shallow to a deep snowpack are unfavourable. The avalanche prone locations are difficult to recognise.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Outgoing longwave radiation during the night will be reduced at times. The surface of the snowpack has frozen to form a strong crust and will soften during the day. Sunshine and high temperatures will give rise to rapid softening of the snowpack at intermediate and high altitudes.
Shady slopes above approximately 2500 m: Faceted weak layers exist in the bottom section of the old snowpack at elevated altitudes.
On steep sunny slopes as well as below approximately 1800 m hardly any snow is lying.
Tendency
The danger of wet avalanches will persist.

Weakly bonded old snow and wet snow require caution.
Slight increase in danger of wet avalanches as a consequence of warming during the day and solar radiation. Wet avalanches can in isolated cases be released by a single winter sport participant. In very isolated cases these can release the weakly bonded old snow as well and reach large size. This applies on very steep shady slopes below approximately 2500 m.
Dry avalanches can additionally be released, even by small loads in isolated cases, especially on very steep northwest, north and northeast facing slopes above approximately 2500 m. Especially transitions from a shallow to a deep snowpack are unfavourable. The avalanche prone locations are difficult to recognise.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Evening and first half of night: Over a wide area a mostly overcast night. Second half of night: A generally clear night.
The surface of the snowpack will freeze to form a strong crust and will soften during the day. The snowpack is moist, in particular on sunny slopes in all altitude zones, as well as on west, north and east facing slopes below approximately 2500 m. Steep west, north and east facing slopes: Faceted weak layers exist in the bottom section of the old snowpack at elevated altitudes.
Tendency
Outgoing longwave radiation during the night will be quite good. The danger of wet avalanches will increase a little during the day.

Increase in danger of wet avalanches in the course of the day.
As a consequence of warming during the day and solar radiation there will be an increase in the danger of wet avalanches. From origins in starting zones where no previous releases have taken place natural avalanches are possible, even medium-sized ones. This applies on shady slopes below approximately 2700 m, as well as on sunny slopes at elevated altitudes. On steep shady slopes avalanches can be released in the weakly bonded old snow and reach large size in isolated cases. Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2500 m. Such avalanche prone locations are difficult to recognise.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Some snow will fall in some regions. The surface of the snowpack will soften during the day. Sunshine and high temperatures will give rise to increasing and thorough wetting of the snowpack below approximately 2700 m. Steep west, north and east facing slopes above approximately 2400 m: Faceted weak layers exist in the bottom section of the old snowpack. Below approximately 1800 m from a snow sport perspective, in most cases insufficient snow is lying.
Tendency
Thursday: The avalanche danger will persist.

Wet snow requires caution.
Only isolated wet avalanches are possible. Caution is to be exercised on extremely steep shady slopes. Mostly avalanches are rather small.
