Wind slabs and weakly bonded old snow represent the main danger.

Wind slabs and weakly bonded old snow represent the main danger.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality. The wind has transported the new snow. In particular at high altitudes and in high Alpine regions sometimes avalanche prone wind slabs formed. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack in all aspects above approximately 2300 m. Single winter sport participants can release avalanches in some places, including medium-sized ones. Off-piste activities call for experience in the assessment of avalanche danger. As a consequence of solar radiation loose snow avalanches are to be expected as the day progresses, but they will be mostly small.

Down to low altitudes snow fell in the last four days. 40 cm of snow, and even more in some localities, has fallen since Sunday above approximately 2000 m. New snow is lying on old snow containing large grains.

Until the afternoon the weather will be sunny. Some mostly small dry avalanches are possible as a consequence of solar radiation.
