Middle Lys Valley

The wind slabs are lying on top of a weakly bonded old snowpack.

Tuesday: As a consequence of the strong southerly wind the prevalence and size of the avalanche prone locations will increase during the night. The conditions will cause a rise in the avalanche danger.

The wind slabs are lying on top of a weakly bonded old snowpack.

As a consequence of a moderate wind, soft wind slabs formed in all aspects. The wind slabs are lying on surface hoar. Even single winter sport participants can release avalanches easily. Mostly they are medium-sized. In some places the avalanches can be triggered in the faceted old snow and reach large size in isolated cases. The danger is greater in areas bordering Piedmont. Backcountry touring and other off-piste activities call for careful route selection. Small and medium-sized natural avalanches are possible.

10 to 30 cm of snow, and even more in some localities, has fallen above approximately 2000 m. The moderate wind will transport the snow. Faceted weak layers exist in the old snowpack in particular on north, east and west facing slopes. Surface frost is present at various exposures and altitudes, now buried by fresh snow. On Sunday on steep slopes small and medium-sized avalanches were reported.
