An area of rain sometimes mixed with thunderstorms will extend Monday morning from eastern Occitanie and the PACA region to the southeast of the Massif Central, Rhône-Alpes to Franche-Comté and the south of Alsace, according to Météo-France
In the middle of the day, Ardèche and Drôme will be placed on orange thunderstorm and rain-flood alert but the last departments in orange in the west of the country have returned to yellow, the meteorological service indicated in its latest bulletin.
Strong gusts of wind
Rainy and stormy activity will be temporarily sustained, particularly from Ardèche and the middle Rhône valley to the northern Alps and the Jura. Significant accumulations of water will be expected in particular in the Drôme and the Ardèche.
As the storms pass, strong gusts will also be feared on the Côte d’Azur. This area will gradually shift east of the Rhône then towards the Alps in the afternoon. More moderate rains will reach Corsica.
Unstable in the rest of the country
In the rest of the country, the start of the morning will be calmer overall, with showers initially limited to the Channel and Atlantic coasts, cloudy skies in the north, sunnier in the southwest.
Then the instability will start again. Showers, interspersed with sunny spells, will increase and cross most regions from west to east. Although less intense than Sunday, the storm lines may be accompanied by a little hail and gusts, particularly from the Center to the northeast quarter. More isolated storms will occur in Languedoc-Roussillon and in the interior of PACA. A calm will appear from the northwest at the end of the day.
