Large wildfires burning in southwestern France have triggered a severe drop in air quality across four departments, regional air quality observatories reported. Plumes of smoke are drifting hundreds of kilometers, affecting areas as far as Saône-et-Loire, Haut-Rhin, and Corrèze. The observatories issued alerts urging residents, especially those with respiratory conditions, to limit outdoor activity and keep windows closed. The blazes, which began earlier this week, have been fueled by dry vegetation and strong winds. Firefighters are struggling to contain the fast-moving flames, with assistance from neighboring regions. The air pollution spike comes during a summer already marked by heatwaves and drought, raising concerns about the growing intensity of wildfire seasons in France. Local authorities are monitoring the situation closely, but the immediate health impact remains the top priority for communities in the smoke path.
