A severe heatwave has placed approximately 53 million people in France under weather alerts this Sunday. Authorities have issued red alerts for 35 departments and orange alerts for another 45. In response to the extreme temperatures, the national railway company, SNCF, recommends that vulnerable individuals avoid traveling by train. The extreme weather is expected to disrupt the traditional Fête de la musique celebrations. Local officials are monitoring the situation as millions remain affected by the heat. These precautions aim to protect high-risk populations from heat-related health emergencies.
