The French traditionally sit down to their Christmas meal late on Christmas Eve, ready to toast the arrival of Christmas Day at midnight.
This year 82,000 families had to eat their meals by candlelight, if they had gas cookers on which to cook them, thanks to Storm Dirk, which blew down power lines and toppled trees onto cables and roads and flooded the centre of one Brittany town.
Shops in the centre of Morlaix were flooded, the town's mayor Agnès Lebrun, who is also an MEP, told RFI.
"Their stocks were full," she added, pointing out that 24 December would usually have been a big sales day. "This means serious damage and I have to say that it was so sudden and brutal that we didn't have the time protect these goods, which have been ruined."
The storm headed south-east down the Rhone Valley towards the Alps on Tuesday night.
Incoming flights were suspended at Nice Côte d'Azur airport on Wednesday morning, although they were expected to resume at about 1.00pm.
