Authorities in Western Balkan countries warned citizens Friday to be cautious, drink water and avoid sunshine during an early heat wave that sent temperatures soaring to up to 40 degrees Celsius (104 degrees Fahrenheit.)
“Don’t stay in the sun between 11 a.m. and 5 p.m.,” warned Serbia’s Public Health Institute in its instructions to citizens. “If you must go out, please take a bottle of water along.”
