After a clear night, conditions will be sunny and mild on Thursday. The zero-degree level will be 2600 m in the north and 2000 m in the south. There will be a light to moderate southwesterly wind. Overnight to Friday and during the day, high cloud will pass through in the west, elsewhere the night will be clear and the day sunny. Temperatures will remain mild and winds will be light.
The danger of dry avalanches will continue to decrease, but only slowly in Grisons due to the weak snowpack structure. Each day, the danger of wet avalanches will increase somewhat as the day progresses.

South of a line from the Rh\u00f4ne 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.

Avalanches can be triggered in near-ground layers and reach large size in isolated cases. Isolated whumpfing sounds can indicate the danger.
