The heat wave, which permanently worries much of France, will end with a strong hurricane devastation affecting 3/4 of the country until Sunday evening and Monday afternoon. This strong deterioration is related to the deepening depression in the Bay of Biscay, which rises from southwest to northeast on Sunday and Sunday nights and reaches the east of the country on Monday. The air mass collision caused by the passage of this air pressure between the hottest air coming from Morocco and the cold air coming from the Atlantic will create violent events.

Several monthly temperatures were recorded, such as Alpi (35.1 ° C), Montelimer (34 ° C), Rhodes (33.1 ° C), Arillock (31.7 C) and Lu Pui (30 .8 ° C). Sense reached 40 in the southwest and lower Rhne Valley.
