Carnic Alps Lesachtal

Weakly bonded old snow requires caution. In particular, however, the danger of wet avalanches will increase as the day progresses.

Weakly bonded old snow requires caution. In particular, however, the danger of wet avalanches will increase as the day progresses.

Avalanches can be released in the old snowpack and reach large size in isolated cases on west, north and east facing slopes. This applies even in case of a single winter sport participant in some cases. The avalanche prone locations are to be found in particular above approximately 2000 m. 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, and at the base of rock walls. The runout zones are to be treated with caution.

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.
