France experienced its hottest day on record Tuesday, with temperatures reaching exceptional levels across much of the country. The southwest saw temperatures between 39°C and 42°C, while eastern regions recorded 34°C to 38°C. Authorities have extended the highest level of heat alert – “vigilance rouge” – to include the departments of Aisne, Somme, Nord, and Pas-de-Calais. This expansion indicates a worsening situation and increased risk to vulnerable populations. The heatwave is prompting concerns about public health and potential strain on infrastructure. Residents are urged to take precautions against the extreme heat, including staying hydrated and avoiding strenuous activity during peak hours. The situation remains dynamic, with further temperature increases possible.
