Middle Lys Valley

Weak layers in the old snowpack represent the main danger.

Weak layers in the old snowpack represent the main danger.

Even single winter sport participants can release avalanches. These avalanche prone locations are to be found in particular on steep north, northeast and east facing slopes. The avalanches can be released in the weakly bonded old snow and reach medium size in some cases. Some small and, in isolated cases, medium-sized natural avalanches are not entirely ruled out. In addition the fresh wind slabs are prone to triggering in some cases still. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger.

Since yesterday on very steep sunny slopes several small and medium-sized avalanches were reported. The old snowpack remains weakly bonded on shady slopes. The high temperatures gave rise to moistening of the snowpack in all regions below approximately 2800 m. As a consequence of falling temperatures a crust will form on the surface on Saturday. The sometimes storm force wind has transported the new snow significantly, especially adjacent to ridgelines and in pass areas above approximately 2300 m. The snowpack will be generally subject to considerable local variations.

Little snow will fall. The avalanche danger will persist.
