Weather alerts are raised a level as storms multiply across France

Four departments now face heightened warnings, with most of France on alert for a combination of storms, winds and heavy rainfall throughout the day

Forecasters have now placed four departments in south and east France on a tier-three orange warning for heavy rain and flooding, as storms continue to pelt much of the country. 

Ain and Isère will join Drôme and Ardèche to face the warnings this afternoon and they are expected to remain in place overnight until Friday. 

Most other departments now face tier-two yellow warnings for a combination of storm alerts, strong winds, and heavy rain with the risk of flooding, both on the western and northern coastlines and across the east of France. 

By Friday, however, the worst of the stormy weather will be over, with only a few departments left facing warnings. 

France set for heavy rains

The four departments facing heightened warnings will begin to be affected this afternoon (September 21), when heavy rain starts to fall alongside the stormy conditions. 

Drôme and Ardèche will face tier-three warnings from 14:00, with Ain and Isère joining around 16:00. 

Elsewhere, as storms roll eastwards across France, most departments will see storm and heavy rain warnings throughout the day. 

This morning, for example, heavy rain and flood warnings are in place across the western stretches of France and around Paris, but by midnight they are in place on the Belgian border and close to Switzerland. 

All in all, 70 departments throughout today will face a warning of some kind. You can find an interactive map showing the warnings on the official Météo France website

By tomorrow (September 22) however, the storms will have mostly disappeared, with only a handful of departments, along the Atlantic coastline and Swiss border, still expected to be subject to warnings.

Storm before the calm… before the warm

The stormy conditions are set to bring a gradual lowering of temperatures.

Temperatures will reach their coldest on Saturday when morning temperatures will be between 6C and 10C and are unlikely to climb above 20C anywhere in the country. 

However, from next week, they are set to rise again, with average highs of 30C in the south – and 27C in the north. 

Early forecasts predict the heat could last into the first days of October.
