Valsavaranche

On wind-loaded slopes the avalanche prone locations are more prevalent.

On wind-loaded slopes the avalanche prone locations are more prevalent.

Wind slabs can especially at their margins be released by a single winter sport participant and reach medium size. Additionally avalanches can also be released in near-ground layers and reach quite a large size. The avalanche prone locations are to be found in particular on very steep northeast, east and southeast facing slopes, in particular at transitions from a shallow to a deep snowpack. Whumpfing sounds serve as an alarm indicating the danger. Isolated medium-sized natural dry avalanches are possible. Such avalanche prone locations are to be found in particular in steep rocky terrain. From the afternoon the wind will be strong. In some regions up to 15 cm of snow will fall. As a consequence of the strong southeasterly wind, fresh snow drift accumulations will form in the course of the day.

As a consequence of a strong wind, hard wind slabs formed in many cases. These are in some cases still prone to triggering in particular on very steep northeast, southeast and south facing slopes. In particular at high altitude snow depths vary greatly, depending on the infuence of the wind. Faceted weak layers exist in the bottom section of the snowpack at intermediate and high altitudes. In all aspects below approximately 2400 m less snow than usual is lying.

The avalanche danger will persist.
