France is preparing for a significant heatwave expected to peak later this week. Météo-France forecasts localized temperatures potentially reaching 40°C (104°F) in regions including Poitou-Charentes, Centre-Val de Loire, Île-de-France, and the Rhône Valley. Paris is anticipated to exceed 35°C (95°F) on both Thursday and Friday. The weather service emphasizes that the highest temperatures will be isolated, not nationwide. Authorities have not yet issued widespread alerts, but residents are advised to prepare for the heat. This heatwave follows a period of generally mild weather, making the sudden increase in temperatures particularly noteworthy.
