On its site Vigilance Météo-France, the institute thus foresees for the territories of the Pyrenees a “rain-snow episode persisting this Sunday, of weak to moderate activity at first”.
The precipitation should strengthen in the evening and “during the night from Sunday to Monday”, specifies the meteorological agency. It could then fall up to 10 mm of rain per hour.
During the night from Saturday to Sunday, Météo-France has already recorded accumulations of between 5 and 10 mm of precipitation, rising to 15 mm locally.
Due to “significant warm weather from west to east on the Pyrenean range”, the snow should also change to rain during the evening of this Sunday, pushing the rain-snow limit above 2000 m. altitude.
Accumulations of 40 to 80 mm in the plains, 100 to 130 mm in the foothills and 150 to 200 in the mountains, or even 250 mm locally, are expected. This episode of intense rain should end “Tuesday during the day”, specifies Météo-France.
