Middle Lys Valley

Fresh wind slabs represent the main danger.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field. Over a wide area new snow and wind slabs are lying on a hard crust. The fresh snow and the wind slabs have bonded quite well with the old snowpack. Above approximately 2000 m snow depths vary greatly, depending on the infuence of the wind. Below approximately 2500 m a little snow is lying. The old snowpack will be generally well bonded.

Friday: The avalanche danger will decrease gradually.

Fresh wind slabs represent the main danger.

15 cm of snow, and up to 40 cm in some localities, will fall in all altitude zones, especially above approximately 2000 m. The sleet will give rise in the afternoon to increasing moistening of the snowpack below approximately 2100 m. As a consequence of new snow and a moderate to strong wind from westerly directions, mostly small wind slabs will form. The fresh and somewhat older wind slabs can be released by a single winter sport participant, especially adjacent to ridgelines and in gullies and bowls. On very steep slopes and above the tree line the likelihood of avalanches is higher. The number and size of avalanche prone locations will increase with altitude. Individual mostly small natural avalanches are possible.
