The equivalent of 2 to 3 weeks of rain
At the end of the night from Saturday to Sunday, a rainy-stormy degradation is set up by the Pyrenees up to the Limousin and should give precipitation locally of the order of 20 to 30 mm / h, indicates the weather operator.
“The expected accumulations are often of the order of 50 mm (or liters / m²) to 60 mm in 24h, which is usually about 2 to 3 weeks of rain in this season,” says Meteo France.
Precipitation is expected to decline in the west Sunday evening.
