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.

In the south, there was broken cloud during the night with a little snow still falling above 1600 m early on. Skies were otherwise clear overnight. Conditions were sunny and mild during the day.

Fresh snow

From Sunday afternoon until precipitation stopped on Monday evening:

• Bernina region: 10 to 20 cm

Temperature

At midday at 2000 m, around +2 °C in the north and -1 °C in the south

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.
