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

A clear night will be followed in the early morning by favourable conditions over a wide area. 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 in isolated cases. Gliding avalanches can also occur. The avalanche prone locations for gliding avalanches are to be found in particular on very steep grassy slopes below approximately 2600 m. Backcountry tours, off-piste skiing and ascents to alpine cabins should be started early and concluded timely.

Outgoing longwave radiation during the night will be 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 from the middle of the day to increasing and thorough wetting of the snowpack on sunny slopes. Towards its base, the snowpack is moist, especially on sunny slopes, as well as in all aspects below approximately 2200 m.
