New snow and weakly bonded old snow represent the main danger.

New snow 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 new snow and wind slabs of the last two days are lying on the unfavourable surface of an old snowpack in all aspects above approximately 2300 m. Medium-sized natural avalanches must be expected. This applies especially on very steep northeast, east and south facing slopes above approximately 2500 m on wind-loaded slopes. Even single winter sport participants can release avalanches in isolated cases, including medium-sized ones. Off-piste activities call for caution.

Down to low altitudes snow has fallen since Sunday. 40 cm of snow, but less in some localities, fell during the night above approximately 2000 m. The large quantity of fresh snow as well as the wind slabs are bonding only slowly with the old snowpack in all aspects. New snow is lying on old snow containing large grains. Tuesday: 10 cm of snow, and even more in some localities, will fall above approximately 2000 m. The northwesterly wind will transport the new snow.

Some mostly small dry avalanches are possible as a consequence of solar radiation.
