Snowpack

On the Main Alpine Ridge and north of it, the increasingly strong southerly wind transports still-loose snow on the shady slopes and forms snowdrift accumulations that are easily triggered. On the northern flank of the Alps, the snowpack structure is otherwise quite favourable. In southern Valais, Ticino and Grisons, there are weak layers prone to triggering in the central part of the snowpack. Especially along the central and eastern parts of the Main Alpine Ridge and south of it, avalanches can also be triggered on shady slopes in near-ground layers of the snowpack.

Individual wet and gliding avalanches are to be expected.

Outlook

Precipitation will fall in the south on Saturday and Sunday. The snowfall level will be between 1400 and 1800 m. On Saturday, 15 to 30 cm of new snow is expected at high altitudes, and 30 to 50 cm on Sunday. The quantities are still uncertain, especially on Sunday. The avalanche danger will increase somewhat on Saturday and appreciably on Sunday.

In the north it will be quite sunny on Saturday with a strong foehn wind from the south. On Sunday it will often be cloudy with showers. The danger of dry avalanches will increase somewhat on Saturday with the foehn wind, but will not change significantly on Sunday. The danger of wet avalanches will increase during the day, probably more so on Saturday than on Sunday.
