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 an increase in the danger of wet avalanches. Wet avalanches can in some places 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. Small and medium-sized natural avalanches are possible in the afternoon. 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.

The surface of the snowpack will freeze to form a strong crust and will soften during the day. Sunshine and high temperatures will give rise to gradual softening of the snowpack at intermediate and high altitudes. Steep slopes: Faceted weak layers exist in the bottom section of the old snowpack at elevated altitudes.

Outgoing longwave radiation during the night will be reduced. The backcountry touring conditions in the morning at elevated altitudes are generally favourable. As the day progresses as a consequence of warming during the day there will be an increase in the danger of wet avalanches. Some rain will fall in some regions.
