An unusually long bout of warm and humid weather across the country has led to a series of thunderstorms that have dropped record amounts of rain in some areas.
National weather service Meteo France said it estimated the number of lightning strikes in May at 182,000 nationwide, almost double the record figure for the same month previously set in 2009.
The weather office estimated that 60 to 80 mm (two-three inches) of rain fell late Monday in some areas of the Normandy region, where a 37-year-old man was found dead near the village of Piseux, in the Eure department which had been on Orange alert for storms.
French weather agency Méteo France had warned members of the public in storm affected areas to be vigilant and avoid unnecessary travel.
The victim is believed to have been involved in a road accident which saw his car flip over and land in a flooded area, a statement from the local government said.
On Tuesday some 28 departments across France were again on Orange alert due to storm warnings.(see map below)
Other badly affected areas on Tuesday included Spechbach-le-Bas in eastern France where 20-40 mm of rain fell in an hour, flooding homes, motorways and
local government buildings near the border with Germany and Switzerland.

The small town of Morlaix in northwestern Brittany was still counting the cost after being submerged on Sunday night when an estimated month's worth of
rain fell within half an hour.
Heavy rain, lightning and sometimes hail have hit wine-growing areas in the Bordeaux, Cognac and Champagne regions over recent weeks, causing major damage to crops.
Storms have also disrupted play at the Roland Garros tennis tournament in Paris and has made conditions tough for professional cyclists in the Criterium du Dauphine race under way in southeastern France.
