Middle Lys Valley

The backcountry touring conditions in the morning, after a clear night, are quite favourable. Gradual increase in danger as a consequence of warming during the day and solar radiation.

The backcountry touring conditions in the morning, after a clear night, are quite favourable. Gradual increase in danger as a consequence of warming during the day and solar radiation.

As a consequence of warming during the day and solar radiation small and medium-sized wet avalanches are to be expected. This applies on steep sunny slopes below approximately 3000 m, and on steep shady slopes below approximately 2500 m. Backcountry tours and ascents to alpine cabins should be concluded timely. The more recent wind slabs of Wednesday can be released by a single winter sport participant in isolated cases. In high Alpine regions these avalanche prone locations are more prevalent. Avalanches can in isolated cases penetrate deep layers. This applies in particular on very steep northwest, north and northeast facing slopes above approximately 2400 m.

The weather will be sunny. The surface of the snowpack will freeze to form a strong crust and will soften during the day. As a consequence of highly fluctuating temperatures a crust formed on the surface during the last six days, this also applies on shady slopes below approximately 2500 m. The spring-like weather conditions gave rise to increasing moistening of the snowpack on sunny slopes below approximately 2900 m, also on shady slopes below approximately 2400 m. Towards its base, the snowpack is wet. This applies in all aspects below approximately 2400 m, and on sunny slopes below approximately 2900 m.

Decrease in danger of moist and wet avalanches as the temperature drops.
