Weakly bonded old snow requires caution. Increase in danger of wet avalanches in the course of the day.

On Friday it will be very mild over a wide area. Shady slopes: The snowpack remains prone to triggering in some places. Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. Outgoing longwave radiation during the night will be good. 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 as the day progresses to thorough wetting of the snowpack in particular on steep sunny slopes below approximately 2600 m. This also applies at the base of rock walls.

In the course of the day the activity of wet avalanches will increase.

Weakly bonded old snow requires caution. Increase in danger of wet avalanches in the course of the day.

Avalanches can be released in the old snowpack and reach large size in particular on west, north and east facing slopes. This applies even in case of a single winter sport participant. The avalanche prone locations are to be found especially on west, north and east facing slopes above approximately 1800 m and in all aspects in high Alpine regions. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack. Remotely triggered avalanches are possible in isolated cases. As a consequence of warming natural avalanches are possible. In their paths avalanches can entrain the wet snow. This extends the avalanche runout distances. As a consequence of warming during the day and solar radiation wet avalanches are to be expected. This applies in particular on very steep sunny slopes below approximately 2600 m, as well as at the base of rock walls. In particular on steep, rather lightly snow-covered east and west facing slopes the wet avalanches can penetrate even deep layers and reach quite a large size. The runout zones are to be treated with caution.
