Switzerland experienced a rough night from Saturday to Sunday with violent winds howling in many places north of the Alps. It often blew at more than 60-80 km/h on the Plateau, or even at more than 90 km/h in the Basel region. And the storm swept the peaks even more violently with gusts often over 100 km/h.
The record was recorded in Säntis, in eastern Switzerland, with a peak of 144 km/h. In the Bernese Emmental, the Bantiger was blown apart at 120 km/h, while at the Jungfraujoch in the Bernese Oberland it blew at more than 113 km/h.
In French-speaking Switzerland, it was on the side of the Diablerets glacier that the wind was the most violent with peaks of 108 km/h. Moléson, in Gruyère, was not to be outdone, with gusts of 107 km/h. Even the summit of Chasseral (BE) was swept away at 103 km/h.
The winds were less stormy this Sunday morning. And from now on, it's going to be snow. Indeed, according to MeteoSwiss, a powerful west then northwest current reigns over Switzerland and will circulate several disturbances which should cause heavy snowfall in the mountains until Tuesday. Some 20 to 60 cm of fresh snow are expected above 1500 m.
As for this Sunday, on the French side, precipitation will be intermittent in the plains, but continuous and often abundant in the mountains. Thunderclaps are not excluded. The rain-snow limit, between 1200 and 1600 meters in the morning, should drop to 700 meters in the afternoon, or even almost in the plain in the evening.
Then, an anticyclone will probably be in place until the end of the year with the passage of a warm front at Christmas. A clear mild spell is expected in the mountains on December 25 with +2°C at 2000 m. In the plains, it will be a maximum of 5°C.
