Danger level

Wet snow

Increase in danger of wet avalanches as a consequence of warming during the day and solar radiation.

Early and late morning:
A clear night will be followed by favourable conditions over a wide area. Individual avalanche prone locations for dry avalanches are to be found in particular on extremely steep shady slopes at elevated altitudes. Avalanches can in some cases reach medium size.

During the day:
As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase gradually on very steep sunny slopes. As the penetration by moisture increases individual natural avalanches are possible in the afternoon. Avalanches can release the saturated snowpack and reach medium size. Backcountry tours, off-piste skiing and ascents to alpine cabins should be started early and concluded timely.

Snowpack

dp.10: springtime scenario

Outgoing longwave radiation during the night will be quite good. The surface of the snowpack will freeze to form a strong crust. In steep terrain there is a danger of falling on the hard snow surface. Sunshine and high temperatures will give rise as the day progresses to a loss of strength within the snowpack in particular on sunny slopes.
Towards its base, the snowpack is moist, especially on sunny slopes, as well as in all aspects below approximately 2200 m.

Isolated avalanche prone weak layers exist in the old snowpack especially on little used west, north and east facing slopes. This applies on shady slopes above approximately 2600 m, as well as on west and east facing slopes above approximately 2800 m.

Tendency

Wet snow represents the main danger.

Danger level

Wet snow

The danger of wet avalanches will increase during the day.

As a consequence of warming during the day and solar radiation individual wet avalanches are possible.
Avalanches can in very isolated cases be released by a single winter sport participant. The avalanche prone locations are to be found in particular on very steep shady slopes at elevated altitudes. Mostly avalanches are small.

Snowpack

The surface of the snowpack will freeze to form a strong crust and will soften quickly. Isolated avalanche prone weak layers exist in the old snowpack especially on steep shady slopes. The snowpack will be generally subject to considerable local variations. Only a little snow is now lying.

Tendency

Low avalanche danger will prevail. The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning.
