Middle Lys Valley

New snow above approximately 500 m.

New snow above approximately 500 m.

Over a wide area 10 to 20 cm of snow, and up to 30 cm in some localities, will fall until the early morning above approximately 1000 m. As a consequence of new snow and a light to moderate southwesterly wind, wind slabs will form adjacent to ridgelines in all aspects as well as above approximately 2200 m. Natural dry avalanches are possible as the day progresses, in particular medium-sized ones. Numerous weak layers exist in the snowpack especially on steep northeast, north and northwest facing slopes. Between approximately 2300 and 2700 m the likelihood of avalanches is quite high. Even single winter sport participants can release avalanches very easily, including large ones. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and artificially triggered avalanches confirm the unfavourable bonding of the snowpack. Careful route selection and spacing between individuals are recommended.

The new snow is lying on top of a weakly bonded old snowpack above approximately 2300 m. Numerous weak layers exist deep in the snowpack especially on steep shady slopes. Adjacent to ridgelines and in gullies and bowls snow depths vary greatly, depending on the infuence of the wind. Below approximately 2500 m a little snow is lying on south facing slopes.

The avalanche danger will persist.
