France is in the grip of a heatwave, which Météo France expects to be “wisdespread, prolonged and intense”. The thermometer is set to climb even higher in the coming days, reaching or exceeding 40°C on June 21, leading to several municipalities to cancel Fete de la Musique celebrations. The state-owned utility EDF has also warned that three nuclear plants face production curbs next week because of high temperatures on the Rhone and Garonne rivers.
