Increase in danger of wet avalanches as a consequence of warming during the day and solar radiation. Weakly bonded old snow requires caution.
As a consequence of warming during the day and solar radiation more frequent wet avalanches are possible. They can in some cases release the saturated snowpack and reach large size in isolated cases. This applies in particular on very steep sunny slopes below approximately 2800 m.
Late morning: Weak layers in the old snowpack can be released in isolated cases by individual winter sport participants. These avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m and on very steep west and east facing slopes above approximately 2600 m. Afternoon: As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase a little. Mostly the avalanches are medium-sized.
Gliding avalanches can also occur. Caution is to be exercised on grassy slopes below approximately 2600 m.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Outgoing longwave radiation during the night was 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. The surface of the snowpack will soften during the day. Sunshine and high temperatures will give rise to increasing and thorough wetting of the snowpack in particular on sunny slopes below approximately 2800 m.
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 2400 m, as well as on west and east facing slopes above approximately 2600 m.
Tendency
Decrease in danger of wet avalanches as the temperature drops.

Increase in danger of wet avalanches as a consequence of warming during the day and solar radiation.
The backcountry touring conditions in the morning, after a clear night, are favourable. As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase. Caution is to be exercised in particular on very steep sunny slopes. Avalanches can in some cases release the saturated snowpack.
Gliding avalanches can also occur. This applies on grassy slopes below approximately 2600 m.
