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

From late morning the likelihood of wet avalanches being released will increase. As a consequence of warming during the day and solar radiation wet loose snow avalanches are possible, especially in case of releases originating from very steep starting zones that still retain some snow. As the penetration by moisture increases wet slab avalanches are possible as the day progresses, in particular medium-sized ones. This applies especially in case of releases originating from shady starting zones, but in isolated cases also in case of releases originating from high-altitude sunny starting zones that have retained the snow thus far. 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 at times. The surface of the snowpack will soften quickly. Sunshine and high temperatures will give rise to increasing and thorough wetting of the snowpack below approximately 3000 m. West, north and east facing slopes above approximately 2500 m: Faceted weak layers exist in the bottom section of the old snowpack at elevated altitudes.

In some regions up to 10 cm of snow will fall. This applies in particular at elevated altitudes in the Venediger Range and in the Glockner Range.
