Middle Lys Valley

At transitions from a shallow to a deep snowpack, when entering gullies and bowls for example the avalanche prone locations are more prevalent.

Avalanches can be released in the weakly bonded old snow, even by a single winter sport participant, in particular on very steep slopes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm sign.

Snow depths vary greatly above approximately 2000 m, depending on the infuence of the wind. In addition, from a snow sport perspective, in most cases insufficient snow is lying. Weak layers exist in the snowpack especially on steep west, north and east facing slopes. As a consequence of rising temperatures and partly cloudy skies a crust formed on the surface, especially on steep sunny slopes between approximately 1900 and 3000 m, as well as on steep shady slopes below approximately 2200 m.

The danger will already be elevated in the early morning. Rain at high altitude: Up to 30 cm of snow, but less in some localities, will fall on Friday above approximately 2800 m. The wind will be strong to storm force over a wide area. As the day progresses, a few, then as the precipitation becomes heavier numerous, and in some cases even medium-sized, dry and wet avalanches are possible.
