Italy heatwave places 19 cities under red alert
Italy is experiencing a prolonged and intense heatwave caused by the expansion of a subtropical anticyclone from North Africa into the Mediterranean. As of August 10, the Ministry of Health has placed 19 cities under a red alert level, including Rome, Naples, Bologna, and Bari. Several other northern cities, such as Milan and Venice, have moved to an orange alert level.
Forecasts indicate that temperatures will peak during the Ferragosto holiday week, with Rome expected to reach 39°C and Milan between 37°C and 38°C. While some instability and intense thunderstorms are expected over the Alps and Apennines, the heat is projected to persist. A possible easing of the heatwave is anticipated between August 17 and August 23.
The extreme heat is compounded by record-high sea temperatures; according to Copernicus, the Mediterranean Sea is approximately three degrees above average. This has increased humidity and discomfort levels across the peninsula, placing significant pressure on emergency rooms in cities like Rome.
