There are distinct weak layers in the middle and lower part of the snowpack, particularly on wind-protected shady slopes. These are particularly common south of a line from the Rhône to the Rhine and on the southern flank of the Alps. In these weak layers, medium-sized and sometimes even large avalanches can still be triggered by human activity. The snowpack on northern and eastern slopes in Valais, as well as in northern Grisons, is particularly prone to triggering. Remote triggering is still possible in these areas in particular. The most recent avalanches triggered in the old snowpack were reported on the northern flank of the Alps at the weekend.

It was cloudy on the southern flank of the Alps. Some snow fell at times above 1000 m. It was sunny in the other regions.

Fresh snow

A few centimetres in the southern Simplon region and in Valle Maggia

Temperature

At midday at 2000 m, between +1 °C in the north and -4 °C in the south

Wind

From the south:

• Moderate and occasionally strong on the northern Alpine ridge
• Elsewhere light to moderate

Temperature

At midday at 2000 m, between 0 °C in the north and -4 °C in the south

Mostly light southwesterly to westerly winds

On Thursday it will be sunny in the east. Clouds will gather in the west and south. On Friday it will be cloudy in the west and south, with precipitation on the Main Alpine Ridge and to the south of it in the afternoon. The snowfall level will be at low altitude. There will be sunny intervals in the east.

The avalanche danger will continue to decrease slowly. Weak layers in the old snowpack will remain prone to triggering, especially in the inneralpine regions.
