Nearly 1,500 people were evacuated from their homes in the Paris region as the swollen river Seine continues to rise with water engulfing riverside walkways.
But the authorities say the worst could soon be over.
According to Michel Delpuech, head of the Paris police body, the river is now rising more slowly and should reach its maximum level either Sunday evening or overnight to around 5.8 or 5.9 metres.
The overflowing waters have led the world-famous Louvre museum to close a basement display of Islamic art. And tourist boats on the Seine have been shut down.
France's second city of Lyon has not been spared with the meeting of two rivers to worry about. The Rhone river has reached a level of 2.82 metres far higher than is usual at this time of year.
Euronews’ Andrea Bolitho says both rivers in Lyon have flooded after several weeks of heavy rain and snow with walkways by the Rhone closed for the first time in their history.
The Saone river level remains extremely high and the Rhone Alpes region is still on high alert, she explains, but with drier weather forecast the end should soon be in sight.
