The Federal Office for Meteorological and climatology (Meteoswiss) issued a level 3 out of 5 slippery road warning. This affects all of western Switzerland and large parts of the Mittelland, as Meteoschweiz announced early Wednesday morning.
There is a significant risk of ice. According to SRF Meteo, freezing rain falls first, which later turns into rain. The temperatures in western Switzerland and the Mittelland are below freezing – in the lowlands at -3 degrees and in the higher valleys at -10 degrees.
In the next few days, low-pressure areas steered fronts into Switzerland. On Wednesday, humid and increasingly mild air will move over the northern side of the Alps during the day. You first ensure the risk of ice, then thaw.
The next surge of moisture from the south-west followed towards Thursday evening, before a cold front settled on the Alps on Friday.
