Border Pennine Alps

Wind slabs and wet snow represent the main danger.

Wind slabs and wet snow represent the main danger.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the high Alpine regions, so that the avalanche danger should be investigated especially thoroughly in the relevant locality. Large quantities of fresh snow and the wind-drifted snow of the last few days can be released by a single winter sport participant on very steep shady slopes and in high Alpine regions, caution is to be exercised in particular, and on extremely steep slopes. A clear night will be followed by generally favourable conditions generally, but the danger of wet avalanches will increase later. The surface of the snowpack will freeze to form a strong crust will soften during the day. The weather conditions will bring about a weakening of the snowpack in the afternoon. In all regions medium-sized and, in isolated cases, large moist and wet avalanches are possible as the moisture increases, in particular on wind-loaded slopes, and in the regions with a lot of snow. Backcountry tours should be started very early and concluded timely.

40 to 60 cm of snow, and even more in some localities, has fallen since Tuesday above approximately 2600 m. Outgoing longwave radiation during the night will be quite good over a wide area. The surface of the snowpack will freeze, but a strong crust will not form and will soften during the day. Further warming. Up to 2500 m rain will fall in some regions. The weather conditions as the day progresses will give rise to increasing moistening of the snowpack. The conditions in all altitude zones are spring-like.
