BERN, SWITZERLAND – The Swiss national weather service, MeteoSwiss, said Wednesday morning 5 December that the storms of the past few days have brought a mix of winds, snow and rain with heavy precipitation to much of Switzerland. The Jura and the north slopes of the Alps had 30-45 litres per m2 Monday night and because the snow line was relatively high, moving up to 1,000-1,500 metres, streams and rivers began to flood.
Canton Valais saw 40 to 70 cm of snow fall in 24 hours, bringing the snow depth to 50-120cm depending on the location. During the latter part of Monday night winds reached 100 to 120km/h in the mountains, 60-80km/h in some areas on the plain.
More snow is forecast and severe weather bulletins are possible for some areas.
