A spokesperson for the Berlin Water Works told Bild that 150 litres of water fell per square metre in the district of western Spandau.
“On average around 580 litres of rain fall every year in Berlin. That means that a quarter of the normal total for the year fell within an 18 hour period,” the spokesperson said.
The state of Brandenburg, which surrounds Berlin, was also hit hard by the severe weather, with up to half a year's rainfall completely swamping some streets.

No further delays are also expected at at Tegel airport on Friday, after flight delays on Thursday.
The capital's transport network took a beating in the storms on Thursday. The Autobahn in the south of the city was blocked off at the Alboinstraße exit in Tempelhof, leading to a huge tailback of traffic. The A100, one of the busiest roads in Germany, was also shut down in the west of the city near the Funkturm.
A house in the Berlin district of Charlottenburg had to be evacuated due to the heavy rainfall, but a structural engineer has since given the all-clear and the 18 evacuees were able to return to the building.
