Vicentine Prealps

Increase in danger of wet avalanches in the late morning.

Increase in danger of wet avalanches in the late morning.

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 isolated cases be released by a single winter sport participant. This applies on very steep shady slopes below approximately 3000 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.

Outgoing longwave radiation during the night will be quite good. 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 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. In particular in the Prealps 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 be elevated in the early morning.
