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 during the day. 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 2700 m, and on steep shady slopes below approximately 2400 m. Avalanches can in isolated cases penetrate deep layers. 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.

Afternoon: The weather will be partly cloudy. This applies below approximately 2200 m. 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 cold. The surface of the snowpack will freeze to form a strong crust and will soften earlier than the day before.
