Current situation
The Atlantic low mentioned last week was the starting signal for our current westerly weather: cold air flowing into the North Atlantic has stimulated the development of low pressure there, the continental high has retreated to the east and the perpetual blocking layers with a meridional flow pattern have been replaced by a dynamic, zonal west or north-west slide. The result is changeable, mild weather with a mixture of excessively warm precipitation and gaps in the sun, also known as "Sauwetter, wo bleibt der Winter?"
Despite the rainy valleys, it is worth mentioning that the base is definitely growing at higher altitudes. In combination with the strong winds of the last few days, the wet fresh snow on the Swiss main ridge at the beginning of the week has caused a four above 2400m and the avalanche situation remains tense.
According to the SLF, the amount of fresh snow from Sunday night to Tuesday afternoon: westernmost Lower Valais, northern Valais, central Upper Valais, Goms, Glarus Alps: 60 to 90 cm. Rest of southern Valais, rest of northern Alps, rest of Gotthard region, northern Grisons, northern Lower Engadine: 30 to 60 cm. Rest of northern Ticino, central Grisons without Gotthard area, southern Lower Engadine, Münstertal: 15 to 30 cm.
