The storm drives away the heat. The arrival of stormy degradation from the west will put an end to the heat wave that has lasted for a week on Thursday. Météo-France thus placed 47 departments on Wednesday vigilance orange storms, over a large western half of France. Rain or even hail is expected in some departments.
Two superimposed vigilances
"The thunderstorms currently present along the Atlantic coast will intensify to become violent from the end of the morning on the West region", indicates Météo-France in its latest bulletin. "In the afternoon, these thunderstorms will reach the Ile-de-France then the Hauts de France in the evening. Moreover, further south, and during the afternoon, the thunderstorms will resume in the south , the Massif Central in particular, then the Center ". Météo-France has warned of "heavy accumulations of rain, hail falls and violent gusts of wind" during this stormy wave which should end early next night.
The heat wave weighing on France will thus be chased away by the stormy degradation which pushed Météo-France to place a large part of the western half on orange vigilance for thunderstorms. The red heat wave vigilance was lifted on Wednesday morning for Eure and Seine-Maritime, still leaving 13 departments of Hauts-de-France and Île-de-France on red alert. And 53 departments are still in orange vigilance, almost all of the rest of the country except for the Atlantic and Mediterranean facades. In part of these regions, in particular Ile-de-France, the two vigilances overlap. Between 33 and 36 ° C are expected from Provence to Hauts-de-France via the North-East.
