Slight 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.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Evening and first half of night: Some snow will fall in some regions. Second half of night: Outgoing longwave radiation during the night will be quite good in some places.
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 rapid softening 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.
Tendency
The danger of wet avalanches will persist.

Wet snow
As a consequence of the rain wet avalanches are possible at any time.
As a consequence of the rain natural wet avalanches are possible. Caution is to be exercised on very steep shady slopes. In very isolated cases avalanches are medium-sized. In steep gullies avalanches can in isolated cases reach areas without any snow cover. The runout zones are to be avoided. Many starting zones have released the snow.
Snowpack
dp.3: rain
The rain will give rise to extreme and thorough wetting of the snowpack. On steep sunny slopes as well as below approximately 1800 m hardly any snow is lying.
Tendency
With the end of the rainfall, the activity of wet avalanches will decrease.

Wet snow
Individual avalanche prone locations for wet avalanches are to be found in particular on very steep shady slopes.
As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase a little.
As the penetration by moisture increases individual wet slab avalanches are possible as the day progresses. This applies in particular in case of releases originating from high-altitude shady starting zones that have retained the snow thus far, especially between approximately 2200 and 2600 m. In isolated cases avalanches are medium-sized. Avalanches can release the wet snowpack. This extends the avalanche runout distances.
Snowpack
dp.10: springtime scenario
Evening and first half of night: Some rain will fall in some regions. Second half of night: Outgoing longwave radiation during the night will be quite good at times. The snowpack is wet and its surface has a melt-freeze crust. The surface of the snowpack will soften quickly. In particular on steep sunny slopes as well as below approximately 1800 m only a little snow is now lying.
Tendency
The danger of wet avalanches will decrease.

Wet snow
Low danger of wet avalanches will persist in some regions. Only a little snow is now lying on north facing slopes.
As a consequence of the rain only isolated wet avalanches are possible. The avalanche prone locations are very rare. Mostly avalanches are small.

In shady places that are protected from the wind only a little snow is lying. The rain will give rise to extreme and thorough wetting of the snowpack.
