Authorities are bracing for more chaos across Central Europe as heavy rain continues to pound the region.
Rail lines were closed in the Czech Republic and homes were evacuated. Flood barriers were erected in Prague for the first time since 2002, when the capital was crippled, with whole districts under water and animals drowned in the local zoo.
The Danube and other Austrian rivers have flooded, swamping entire villages, with some houses covered to the first floor. The fire brigade worked overnight to pump out cellars and important infrastructure buildings and to keep the roads clear. An electric power station is under water in Salzburg.
In Germany, Passau is intersected by three rivers, including the Donau, which has already burst, covering streets and a bridge with water.
Rain, up to 15 litres per square metre in volume, is forecast to continue across most of Bavaria and Saxony .
