Italy puts all major cities on highest alert as heatwave intensifies

ROME, Aug 4 (Reuters) – Italy is placing all its 27 major cities under its highest heat alert on Thursday, as the ​country’s fourth heatwave of the summer ‌intensifies, the health ministry said on Tuesday.

Twenty-five cities were put on red alert on Tuesday and Wednesday, with the only two currently on a lesser amber alert, ‌Messina ​and Reggio Calabria in the ⁠far south of the ⁠country, moving up to the maximum level on Thursday.

A red alert indicates a potential health emergency with prolonged high temperatures posing a ​serious health risk to the entire population, including young and healthy people.

Local authorities urged ⁠residents in affected areas to ⁠avoid exposure to heat and direct ​sunlight during the hottest hours of the day, ​between 11:00 a.m. and 6:00 p.m., stay indoors ‌where possible and drink plenty of fluids.

A spokesperson at the health ministry said it was the first time this year that all 27 ⁠cities had been issued with a red alert, but could not confirm if this had ever happened ⁠in previous ‌years.

Temperatures have climbed to 40 degrees ⁠Celsius (104 degrees Fahrenheit) in some areas ​of ‌Italy and little relief is expected ​before the ⁠weekend. Forecasters say the heatwave is being fuelled by a North African anticyclone that has strengthened over the Mediterranean and stretched across much of Europe.
