Middle Lys Valley

Fresh wind slabs represent the main danger.

Fresh wind slabs represent the main danger.

5 to 15 cm of snow will fall from the afternoon above approximately 1800 m. As a consequence of new snow and a moderate to strong southeasterly wind, sometimes avalanche prone wind slabs formed on Monday. The avalanche prone locations are sometimes covered with new snow and are therefore difficult to recognise. In particular above approximately 2300 m the avalanche prone locations are more prevalent. The fresh snow and the wind slabs can be released easily, even by a single winter sport participant,. 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. Backcountry touring and other off-piste activities call for meticulous route selection. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate a sometimes treacherous avalanche situation on very steep shady slopes. Several small and, in isolated cases, medium-sized dry and moist avalanches are possible as the day progresses. This applies in particular on extremely steep slopes below approximately 2500 m, in the event of prolonged bright spells in particular.

25 to 40 cm of snow, and even more in some localities, fell in the last four days above approximately 2000 m. The wind was moderate to strong in some localities. 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: Towards its surface, the snowpack is dry and has a loosely bonded surface. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack on steep shady slopes above approximately 2400 m. In all aspects less snow than usual is lying. On sunny slopes below approximately 2500 m hardly any snow is lying.

Little snow will fall. The avalanche danger will persist.
