Middle Lys Valley

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

The surface of the snowpack will freeze to form a strong crust and will soften earlier than the day before. As a consequence of warming during the day and solar radiation small and medium-sized moist and wet avalanches are possible. This applies on steep sunny slopes below approximately 2900 m, and on steep shady slopes below approximately 2400 m. Avalanches can in isolated cases penetrate deep layers reach large size in isolated cases. This applies in particular on very steep west, north and east facing slopes above approximately 2400 m. Backcountry tours and ascents to alpine cabins should be concluded timely.

Wednesday: High Alpine regions: Little snow will fall in the evening especially along the border with France. Thursday: Very early morning: The weather will be partly cloudy along the border with France. 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. Towards its base, the snowpack is wet, also on shady slopes below approximately 2400 m. These weather conditions gave rise to settling of the snowpack in particular on sunny slopes.

The weather will be warm. The surface of the snowpack will only just freeze and will soften earlier than the day before.
