Persistent rain in France to elevate flood risk this weekend

Wet weather will once again dampen France on Saturday and Sunday, and rain will be heavy enough to cause flooding issues by next week.

A weak front will move along the southern part of the country on Saturday. This will bring periods of rain from Aquitaine and Midi Pyrenees to Franche Comte and northern Rhone Alpes through much of the day. This includes the cities of Lyon and Toulouse.

On Saturday, the northeastern part of the country will have a brief break in the wet weather, including the cities of Paris and Nancy. Instead, there will be a mix of sun and clouds.

However, a new wave of wet weather will quickly follow the dry break. On Saturday morning, showers will spread across Bretagne, Pays de la Liore and Basse-Normandie. By the afternoon, these areas will get periods of steadier rain.

This includes the city of Nantes, where 68 mm (about 2.68 inches) of rain has already fallen in the first five days of the new year. The normal amount of rain for the entire month of January is 71 mm (2.80 inches) for the city.

Rain will persist for Nantes and the surrounding area during Saturday night, before tapering off to just showers late in the day on Sunday.

Rain will spread from west to east across the country on Sunday with this front.

Rainfall totals of 5-20 mm (0.20-0.75 of an inch) are generally expected across the country into Sunday afternoon. The heaviest rain will likely remain along the coasts of Bretagne and Pays de la Loire, and in the southern half of the country.

The same areas that will receive several millimeters of rain on Saturday will be hit again with heavier rain on Sunday. In these areas, up to 75 mm (3 inches) is possible.

"The heaviest rain will likely remain in parts of Aquitaine and Midi Pyranees," AccuWeather Meteorologist Tyler Roys said. "Following a very wet last few weeks, this is an area that is not in need of more rain, so there is the threat for localized flooding into Sunday evening."

Waves of rain are expected to continue into southwestern France on Monday. Another 25 mm (1 inch) of rain are possible, aggravating any flooding problems that could start over the weekend.
