Wildfire smoke from France and Spain reaches Czech skies

Meteorologists have detected smoke from major wildfires in France and Spain high above the Czech Republic. According to the Czech Hydrometeorological Institute, the smoke layer was observed early on Sunday at an altitude of between three and 4.5 kilometres, meaning it poses no risk to air quality at ground level. The plume was also visible on satellite images as a thin haze over the country. France and Spain continue to battle extensive wildfires that have forced the evacuation of an estimated 300,000 people. Czech firefighters are among the international crews helping to tackle the blazes in France.
