GENEVA, SWITZERLAND – The dose of winter that arrived in most parts of Switzerland over the weekend is about to be backed up by heavy snow in several areas, mixed at times with high winds and ice.
MeteoSwiss issued a weather bulletin Monday morning 3 December stating that unstable weather will reach the region Monday afternoon, provoking “abundant precipitation during the night and early Tuesday morning.”
The snow line will very quickly move up to 1,000-1,500 metres, then fall again to 500 metres during the morning Tuesday.
The Jura and pre-Alps, at altitudes of 1,000 to 1,500 metres, can expect rainfall to be 10-30mm. Most of this is expected to melt during the night, adding to runoff from the predicted heavy rainfall.
Continual snowfall is forecast for canton Valais between noon Monday and noon Tuesday. Snow depth of 40-60cm will be added to the 50-11cm already on the ground in the region.
High winds from the west, with gusting from 80-110 kph, are expected.
