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. This applies on very steep northwest, north and northeast facing slopes below approximately 2500 m, as well as on very steep west and east facing slopes below approximately 2800 m, but in isolated cases also on very steep sunny slopes at elevated altitudes. The surface of the snowpack will soften earlier than the day before. 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 in very isolated cases be released, mostly by large additional loads, especially on very steep northwest, north and northeast facing slopes above approximately 2500 m. The avalanche prone locations are very rare but are difficult to recognise.

Outgoing longwave radiation during the night will be reduced in some case. The surface of the snowpack will freeze to form a strong crust and will soften earlier than the day before. Sunshine and high temperatures will give rise to gradual moistening 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 low and intermediate altitudes hardly any snow is lying.

Outgoing longwave radiation during the night will be reduced. The danger of wet avalanches will already increase in the late morning.
