The weather will be rainy on Friday, according to Météo-France forecasts, which have placed the Ardèche and the Drôme in orange rain-flood vigilance.

Flood risk
“The intensities of rain increased last night in the Ardèche Cévennes.
Since yesterday morning [this Thursday], there have been up to 100 to 120 mm.
The rains remain light and scattered towards the Rhone Valley,” they reported.
The rains, which can sometimes have a stormy character, "maintain on the relief with some periods of calm" and the accumulations could "reach 150 to 250 mm over the whole episode (between Thursday and Saturday morning) on the Ardèche Cevennes”.
As a result, the upstream basin of the Ardèche River is on orange alert for the risk of flooding.
Up to 120 mm of rain in 24 hours
During this day on Friday, the axis of heavy rain will shift towards the Rhône valley then the rest of the Drôme, before sliding even further east (Isère, Préalpes).
The accumulations could then reach 100 to 120 mm in 24 hours, locally more, in these areas.
A potentially strong storm activity should be monitored, particularly in the Rhône Valley.
From Languedoc, from the interior of the PACA region and from Rhône-Alpes to Franche-Comté, the day will also be rainy.
It will rain less on the Côte d'Azur.
Corsica will keep dry but cloudy weather.
Under a temporarily very cloudy sky, showers will circulate from the Massif Central to Burgundy and the Grand-Est.
They will still be locally stormy over the North-East.
Up to 22 degrees on the northern half, and up to 29 in Corsica
On the plains of the South-West, the showers will be rare under a bright but veiled sky.
On the relief of the Pyrenees, the rains will still be temporarily sustained but the wind will blow more moderately than the day before.
From Poitou-Charentes to the north of the Seine, the sometimes stormy showers at the start of the day will give way to good sunny moments, interspersed with isolated showers.
On the other hand, pushed by a southwest wind of 60 to 80 km / h, clouds and showers will invade Brittany and Normandy.
Minimum temperatures will show 13 to 16 degrees in general, locally 17 to 20 south of the Garonne and around the Mediterranean.
The maximum will reach 18 to 22 degrees on the northern half and Auvergne-Rhône-Alpes, locally 16/17 in Brittany.
