And four. After a cooling in certain regions, Météo-France forecasts further temperature increases from Sunday and a worsening of the dryness of the soil despite the storms. “After a refreshment by the northwest of the country this weekend, the temperatures are rising again from Sunday on the south-west and reach the northern half on Monday”, announced Météo-France on Friday evening. On Sunday, “we expect 33°C to 35°C in the south-west, while temperatures remain stationary or are slightly down in the Mediterranean regions”, specifies the situation update.
“On Monday, the rise in temperatures continues and reaches the northern half: we expect 35°C to 37°C from the southwest to the southeast, and 30°C to 34°C further north, except for a small quarter northwest which remains below 30°C”, according to Météo-France. “Maximum temperatures between 32°C and 36°C could most likely be sustained over much of the country. »
For the time being, “there remains uncertainty” as to whether these developments should be considered as an “interruption” of the “third summer heat wave “, which began on July 31, explains the meteorological service: “on a national scale, it could end at the beginning of the weekend thanks to a drop in temperatures over three quarters of the country or continue”.

In Corsica, this daily record has even been beaten every day since the beginning of July and since mid-May in PACA. “This situation constitutes a major event comparable to the droughts of 1976 and 2003”, underline the meteorologists. “By the middle of August, it is very likely that this dry soil situation will get even worse in a large number of regions. »
