A stormy current from the Pyrenees has covered eastern France since Saturday afternoon. This episode will be accompanied by heavy rains.
Sunday, June 26, will be marked by heavy rains and numerous thunderstorms over a large part of eastern France, announces The Weather Channel *. A mass of cold air coming from the West will indeed find itself blocked by a persistent warm current coming from the Pyrenees. This blockage, which is likely to last all day Sunday or even beyond, causing repeated thunderstorms in the regions concerned. A total of 20 departments are placed on orange alert.

During the night from Saturday to Sunday thunderstorms should thus break out in the Cévennes but could also affect more southern departments such as Hérault and Gard, especially between 5 and 9 am. During the day, this phenomenon will persist, accompanied by rain. This time the Pyrenees, Occitania and the Massif Central will be mainly concerned, especially in the afternoon. In total, an accumulation of 50 to 80 mm of water could be locally recorded, adding to the rains of the week. Such precipitation will probably have an impact on the flow of rivers in the region (Loire upstream, Allier upstream, Gardons des Cévennes, tributaries of the Tarn…). Caution is therefore called for.
