Increase in danger of wet avalanches in the course of the day.

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 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. Avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2500 m. These places are very rare but are difficult to recognise.

Outgoing longwave radiation during the night will be reduced at times. 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 elevated altitudes. On steep sunny slopes as well as below approximately 1800 m hardly any snow is lying.

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