Waadtländer Voralpen

Snowpack

North of a line from the Rhone to the Rhine and in the extreme west of Lower Valais, weak layers in the snowpack are mostly thickly covered and are now hardly triggerable by human activity.

South of a line from the Rhône to the Rhine, the persistent weak layers that have been a feature since the beginning of January are still present. However, the number of avalanche-prone locations has decreased significantly. Reports of avalanches and alarm signs indicate that the situation in Grisons remains the most precarious.

Weak layers in the lower part of the snowpack are being weakened as they become moistened for the first time. Wet slab avalanches are possible as the day progresses. These can occur naturally but can also be triggered by winter sport participants, at present mainly on sunny slopes below approximately 2600 m.

Outlook to Saturday

There will be clear spells during the nights with fairly sunny conditions during the days. Temperatures will remain mild, with zero-degree levels between 2600 m in the north and 2200 m in the south. Winds will be light.

The danger of dry avalanches will continue to decrease, but only slowly in Grisons due to the weak snowpack structure. The danger of wet avalanches will increase over the course of each day, but somewhat earlier than on previous days due to slightly reduced outgoing longwave radiation during the night.
