Red alert across Sicily's cities as Europe's heatwave tightens grip

Italy's health ministry placed all major cities on red alert ahead of the weekend, from Trieste in the northeast to Palermo in Sicily, as a blistering heatwave across much of Europe toppled temperature records and disrupted energy and transportation systems, France 24 reported. The alert covers 27 cities, with temperatures approaching or exceeding those recorded during the infamous summer of 2003, according to The Local Italy.

The heat has set a national temperature record in neighbouring Austria, fueled wildfires in France and strained infrastructure across the continent, CBS News reported. In Rome, commuters are sweltering on the Metro C line, where high temperatures and air conditioning systems struggling with conditions they were not designed for have exposed the city's vulnerabilities, The Local Italy said.

For Sicily, the red alert is more than a health warning. The island has endured a summer of drought and wildfire, and the heat now bears down on an agricultural sector already counting the cost of a parched season. Palermo, listed among the cities on red alert, faces a weekend of emergency services on standby and vulnerable residents urged to stay indoors.

The current heatwave is part of a broader European pattern. Austria recorded its highest temperature ever, while wildfires in France and power outages across several countries have forced governments to respond, CBS News reported. Italy's health ministry has extended the red alert to cover cities from the Alps to the Mediterranean coast, signalling that the heat is not a localised event but a continental one.

The comparison to 2003 is significant. That summer, an estimated 70,000 excess deaths were recorded across Europe, and the heatwave became a reference point for climate vulnerability. The Local Italy reported that temperatures in many parts of the country are now approaching or exceeding those of 2003, raising concerns for public health systems already stretched by an ageing population.

In Sicily, the heat compounds a longer crisis. The island's water reserves have been depleted by months of below-average rainfall, and farmers have watched crops wither. While the red alert focuses on immediate health risks, the longer-term threat is to the land itself: a hotter, drier Sicily that struggles to sustain the agriculture that has defined its economy for centuries. The weekend forecast offers little relief, with the health ministry warning that the alert will persist as the heatwave continues to grip Europe.
