Valgrisenche

Fresh wind slabs require caution.

Fresh wind slabs require caution.

As a consequence of new snow and a moderate southeasterly wind, further wind slabs formed. The avalanche prone locations are to be found adjacent to ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. In the areas closest to the French border: Here the avalanche prone locations are more prevalent. Even single winter sport participants can release avalanches in some places. The avalanches can be triggered in the faceted old snow and reach medium size in isolated cases. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication of a weakly bonded snowpack. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger. In highly frequented off-piste terrain and on popular backcountry touring routes the snowpack is more stable. Mostly small natural avalanches are possible.

10 to 20 cm of snow has fallen since Tuesday above approximately 2000 m. Several medium-sized dry slab avalanches have been released by people. Weak layers exist in the old snowpack on shady slopes. The new snow of the last few days is lying on surface hoar in some places. At intermediate and high altitudes snow depths vary greatly, depending on the infuence of the wind. The numerous rocks hidden by the recent snow are the main danger.

The weather will be sunny.
