Heavy rain continued in Switzerland overnight, particularly in the centre of the country.
Lake Lucerne, Lake Biel and Lake Thun are all threatening to break their banks, while Lake Zurich has already done so as of Friday morning.
As of Saturday, the weather is expected to improve – however the flood danger is set to remain critical.
Wetterbesserung in Sicht!
Bis morgen Samstag bleibt es wechselhaft mit Regengüssen und lokalen Gewittern. Am Sonntag nur noch entlang der Berge einzelne Schauer. Nächste Woche recht sonnig, die Hochwassersituation wird sich dann definitiv entspannen. https://t.co/2HbU97BwMO (rv) pic.twitter.com/VzjRMi2IkD
