France is preparing for a major heatwave, with 49 departments placed on red alert and 40 on orange alert. The heatwave is expected to significantly disrupt daily life, leading to the closure of hundreds of schools on Monday. Train services in the Île-de-France region are also being cancelled as a precautionary measure. Météo-France forecasts overnight temperatures as high as 26°C (79°F) from Sunday to Monday. The alert levels indicate a high risk to vulnerable populations and widespread impacts on infrastructure. Authorities are urging citizens to take precautions against the heat, including staying hydrated and avoiding strenuous activity during peak hours. This heatwave follows record-breaking temperatures experienced in other parts of Europe.
