Several wildfires prompt disruptions in Athens.

Heat warnings have also been issued for Bosnia and Herzegovina, Bulgaria, Italy, Romania, Serbia and Turkey. Residents of Athens, have been warned to stay indoors with their windows closed because of poor air quality after a wildfire raged Tuesday in the suburbs north of the capital. The extreme heat forced to close the Acropolis and other ancient sites. 
Monitor local media for weather updates and related advisories. During heatwaves, remain indoors in air conditioning when possible. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Charge battery-powered devices in the case of prolonged electricity outages. Major flight disruptions are unlikely at regional airports, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads.
