Snowpack

The southerly wind transported the little new snow in the south and the loosely bonded old snowpack in the north, especially on shady slopes. The wind slabs were deposited over a wide area on an unfavourable and faceted surface of old snowpack.

In the last few days, hardly any avalanches have been triggered in the deep old snowpack. Nevertheless, caution is necessary south of a line from the Rhône to the Rhine because there are still weak layers in the lower part of the snowpack. These are most pronounced on shady slopes protected from the wind in Ticino, central Grisons, the Engadine and the Grisons southern valleys. If avalanches are triggered here, they can take the entire snowpack with them and become dangerously large.

The number of gliding avalanches has decreased slightly. However, they can still become large.

Weather forecast to Sunday

In the north it will be partly sunny, in the south very cloudy with precipitation. The snowfall level will rise to 1000 m.

Fresh snow

From Saturday afternoon to Sunday afternoon:

• Ticino, Moesano and Bernina region: 10 to 15 cm.
• On the rest of the Main Alpine Ridge: about 5 cm.

Temperature

At midday at 2000 m, around -2 °C.

Wind

• The foehn wind from the south will end during the night.
• Mostly light southerly wind during the day.

Weather review for Saturday

In the northeast, it was bright and clear due to the foehn wind and overcast elsewhere. In the south, it snowed at low altitudes.

Fresh snow

Up until Saturday afternoon, the following amounts of snow fell above approximately 1200 m:

• Main Alpine Ridge from the Monte Rosa to the Lower Engadine and south of it: up to 10 cm.

Temperature

At midday at 2000 m, between +1 °C in the north and -5 °C in the south.

Wind

• Moderate in the south, otherwise strong southerly winds.
• Foehn wind in the valleys of the north.

Outlook

On Monday, it will still be quite sunny in the east in the morning. Elsewhere, it will be very cloudy and some snow will fall in the west and south above approximately 1200 m.

The weather forecast for Tuesday is still uncertain. It is probable that it will be cloudy with brighter spells, especially in the inneralpine regions. Some snow will fall above approximately 1200 m. On both days, the southwesterly wind will be strong in places at high altitudes in the west, and light to moderate elsewhere.

The avalanche danger will not change significantly on Monday. On Tuesday, it may increase slightly in some regions depending on the amount of new snow.
