Torrential rain, thunderstorms and flash floods have inundated towns and villages, especially in parts of northwest, central and eastern Switzerland in recent days. Heavy rain over the past few days has caused damage to homes and infrastructure in cantons Solothurn, Aargau and Basel-Country, with numerous cellars and roads flooded. The police and fire services were called out 400 times in Aargau alone, and in several areas civil protection volunteers were out in force. In the town of Stetten 60 millimetres of rain fell in three hours. Rail services were affected between Lenzburg and Othmarsingen on the Zurich-Aargau line. In Oftringen a barn was set ablaze after being struck by lightning but no one was injured. On Wednesday afternoon the A1 motorway was flooded near Lenzburg causing tailbacks for over an hour. The Solothurn police received 110 calls for help, mostly due to flooded cellars and small landslides. In central Switzerland the region between Bern and Chietres in canton Fribourg was badly hit by torrential rain. Trains on the Bern-NeuchÃ¢tel and Bern BrÃ¼nnen Westside and Chietres were delayed. In Zurich and Fribourg 58 millimetres of rain fell in 12 hours. French-speaking Switzerland has generally escaped the heavy rains and flooding. The MeteoSwiss weather service warns, however, that the entire Jura region could witness violent storms and floods similar to those on Tuesday, which caused power shortages in canton Basel Country and the closure of the Transjurane (A16) motorway. A violent storm hit Geneva on Wednesday afternoon causing a large tree to fall across the 12 tram line, delaying traffic. No injuries were reported. After days of continual rain, the MeteoNews weather service warns of a high risk of floods and landslides in the central and eastern alpine region. Heavy rain is expected to continue in the German-speaking regions and may cause local damage on Thursday, MeteoNews said in a statement on Wednesday. Around 50mm of rain, and up to 80mm in some areas, is expected across the central and eastern central alpine region. The levels of streams and rivers such as the Aare, Thur, Emme, Petite Emme and Sihl are expected to rise until Friday.
