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

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 above approximately 2000 m and in all aspects at elevated altitudes. 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 2400 m, as well as at the base of rock walls. In addition a latent danger of gliding avalanches exists. This applies in particular on cut and grassy slopes.

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. Sunshine and high temperatures will give rise as the day progresses to thorough wetting of the snowpack. This applies especially on very steep sunny slopes below approximately 2400 m.

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