Swathes of southern and eastern Europe sweltered in temperatures above 40 degrees Celsius (104°F) on Friday in a heat wave nicknamed "Lucifer" that has fanned forest fires, triggered weather warning alerts and damaged crops.
Italy and the Balkans were worst affected, though areas as far north as southern Poland also basked in abnormally hot temperatures, and European weather hub Meteoalarm issued its highest grade "red" warnings for 10 countries.Wine growers in Italy have started gathering the grape harvest weeks earlier than usual due to the extreme heat.

Carlo Petrini, founder of the Slow Food movement, wrote in La Stampa newspaper that the grape harvest had never started before Aug. 15 in living memory.
"The health of the grapes is severely tested by this weather," Petrini wrote, adding that growers ran the risk of finding the fruit "cooked by the sun and the burning heat".
