The river Seine floods following heavy rainfalls on June 4, 2016. Parisians were urged to stay away from the Seine, which has spilled over its banks in places and on June 3 rose 6.07 metres (19ft 9ins) above its normal level. Authorities said the river could swell to "perhaps 6.5 metres (21 feet) in a worst-case scenario", comfortably beating a level reached during floods in 1982. The record remains the 8.68 metres reached during devastating floods in 1910.
