Der grosse Schnee in den Schweizer Alpen kam sehr spät. Vielerorts 50 - 100 cm Neuschnee, im Hochgebirge noch deutlich mehr. myweather.ch/winter/DAV

In Davos konnte ein historischer Tiefstand der Schneedecke für Mitte Februar gerade noch abgewendet werden. Bis 1980 wurde die Schneehöhe vermutlich an einem Ort mit stärkerer Sonnenexposition gemessen. Entsprechend ist der Vergleich schwierig. myweather.ch/winter/DAV

Ergiebige Niederschläge im Westen und Wallis. Dadurch steigende Abflüsse im Flachland. Hier spezifischer Abfluss. Übersicht: myweather.ch

There is great uncertainty after 8 December regarding storm tracks over the eastern Atlantic, according to multi-model ensembles.

Blocking pattern prevents storms from reaching Central Europe. Northwestern Europe will experience a number of stormy and wet days, however.

Conditions for storm formation over the Atlantic become more favourable during the next days. Multi-model ensemble track forecast.

Calm weather over Central Europe over the next couple of days. The Atlantic low will not move further east than the British Isles.

Forecast tracks for Tropical Storm 33W (Koto) and Tropical Cyclone 05B (Ditwah). The main threat is not wind but excessive rainfall. The landfall locations are highly uncertain at this point.

Storm activity over the Atlantic and Western Europe: The track of the first low, which passes over the Faroe Islands, is quite certain, but thereafter, uncertainty reigns!

Intensive storm low to affect Northwestern Europe later this week. Multi-model ensemble tracks.
