Snowpack

In the regions south of a line from the Rhône to the Rhine, there are distinct weak layers in the lower part of the snowpack. These are particularly pronounced in Ticino, central Grisons, the Engadine and the Grisons southern valleys, especially on shady slopes protected from the wind, where avalanches can sweep away the entire snowpack. Isolated avalanches may still be remotely triggered. The number of avalanche prone locations is slowly decreasing. The number of reported avalanches triggered has also decreased in recent days.

Avalanches may be triggered in the regions north of a line from the Rhône to the Rhine, especially in weak layers in the upper part of the snowpack. Fractures in deep layers of the old snowpack are unlikely here.

Isolated gliding avalanches, mainly moderate in size, may still occur.

Outlook

Thursday will be mostly sunny, with low stratus cloud as the day progresses, especially in the Prealps. There will be mostly light winds from the northeast, shifting to the west as the day progresses. There will be a moderate Bise wind in the Prealps. On Friday, it will be partly sunny in the north with a foehn wind from the south. In the south, it will be very cloudy and a little snow may fall down into the valleys as the day progresses. Moderate to strong southwesterly winds will blow at high altitudes and there will be a moderate foehn wind from the south in the regions exposed to the foehn wind in the north.

The avalanche danger will continue to decrease on Thursday, but only very slowly in southern Valais, Ticino and Grisons due to the weak snow layering. The avalanche danger may increase somewhat on Friday with fresh drift snow.
