Two people have died and more than 150 people have been airlifted to safety after floods hit south-eastern France, according to local authorities, reports BBC News.
One man died in his basement and another was swept away in his car while a third person was missing in a boat in the Var area.
Some 4,000 homes have been left without power, officials say.
Local official Laurent Cayrel told a news conference that there had been "record rainfall".
"The situation is very worrying, and it's not going to get any better tonight," he told reporters on Sunday, amid forecasts of further rainfall.
By Sunday evening, 155 people had been airlifted from the worst-hit areas and the evacuation of residents by boat was continuing.
One woman, who was evacuated by helicopter with her five-year-old daughter, said she had seen a huge wave wash her empty car away.
