Fresh wind slabs represent the main danger.

Fresh wind slabs represent the main danger.

As a consequence of a moderate to strong wind from westerly directions, soft wind slabs formed on Thursday. The avalanche prone locations are sometimes covered with new snow and are therefore difficult to recognise. The fresh snow and the wind slabs can be released by a single winter sport participant in some cases. This applies especially at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example, as well as on very steep shady slopes. Several small and, in isolated cases, medium-sized dry and moist avalanches are possible, in particular on extremely steep slopes, as well as in steep rocky terrain below approximately 2600 m, in the event of prolonged bright spells in particular.

15 to 25 cm of snow fell in the last four days above approximately 2000 m. The wind was moderate to strong in some localities. 5 to 10 cm of snow will fall on Friday above approximately 1800 m. The high humditiy gave rise to moistening of the old snowpack in all aspects below approximately 2400 m. The new snow and wind slabs are lying on a crust on steep sunny slopes. In shady places that are protected from the wind above approximately 2500 m: The new snow and wind slabs are lying on the unfavourable surface of an old snowpack on steep shady slopes above approximately 2400 m. Towards its surface, the snowpack is dry and has a loosely bonded surface. In all aspects less snow than usual is lying. Adjacent to ridgelines and in pass areas and at high altitude a little snow is lying. At low altitude less snow than usual is lying. On sunny slopes below approximately 2600 m hardly any snow is lying.

Little snow will fall. The avalanche danger will persist.
