Snowpack

In near-surface layers, there are sometimes weak layers in which avalanches could be triggered. In addition, the Bise wind in the Jura and the Prealps and the strong northerly wind in the south have led to the formation of snowdrift accumulations that are prone to triggering.

On the central part of the southern flank of the Alps and in southern Upper Engadine, the old snowpack structure has been partially transformed, especially in places with little snow, and fractures deeper in the snowpack are possible in isolated cases. In the other regions, the old snowpack structure is generally favourable. Hardly any fractures deeper in the snowpack are to be expected there.

Only individual medium-sized and, rarely, large gliding avalanches are still expected, especially at altitudes between 2000 and 2500 m.

Weather forecast for Monday, 08.01.2024

During the night, some snow will fall in the north down to low altitudes. During the day, it will remain cloudy on the western part of the northern flank of the Alps and in the Prealps, and there will still be a little snowfall in the Prealps. In the other regions, the afternoon will bring clear spells in the mountains.

New snow

From Sunday afternoon to Monday afternoon, the following amounts of fresh snow are expected above approximately 800 m:

• eastern Jura, central and eastern parts of the northern flank of the Alps: 5 to 10 cm, locally up to 20 cm;
• elsewhere: a few centimetres of snow, with the central part of the southern flank of the Alps remaining dry.

Temperature

At midday at 2000 m, -6 °C in the west, -8 °C in the north and east and -4 °C in the south.

Wind

• In the Prealps and the Jura, there will be a moderate to strong Bise wind during the night. This will ease during the day.
• Elsewhere there will be mostly light winds.

Weather review for Sunday, 07.01.2024

New snow

From Saturday afternoon to Sunday afternoon, the following amounts of fresh snow were recorded above 1000 m:

• eastern Jura, central and eastern parts of the northern flank of the Alps: 15 to 30 cm;
• western part of the northern flank of the Alps, Grisons: 5 to 15 cm;
• elsewhere: less, or it remained dry.

Temperature

At midday at 2000 m, -7 °C in the north and -3 °C in the south.

Wind

• There was a moderate to strong Bise wind in the Jura and the Prealps.
• Elsewhere there was a partly moderate wind, with strong northerly winds on and to the south of the Main Alpine Ridge.

Trend until Wednesday, 10.01.2024

In the north, it will be somewhat sunny in the mountains on Tuesday and mostly sunny on Wednesday. The temperature at midday at 2000 m will rise towards -4 °C. A little snow may fall in the south and the temperature at midday at 2000 m will drop to -6°C. There will be a light wind.

The avalanche danger will decrease.
