Italy's 27 Cities on Red Alert as Fourth Heatwave Tests Genoa's Port

Italy is to place all of its 27 major cities, from Trieste in the north to Palermo in the south, under the highest heat alert as the fourth heatwave to hit the country this summer intensifies, the Guardian reported on Wednesday. The red alert comes as temperatures in some areas edge close to 40C, according to the paper's Rome correspondent.

For the Ligurian coast, the warning carries a particular weight. The port of Genoa, the country's largest and a critical node for Mediterranean shipping, now faces the practical question of how a prolonged heat event affects cargo handling, container terminal operations and the thousands of dockworkers who move freight along the waterfront each day.

The red alert system, which the Italian health ministry operates across major urban centres, signals the highest level of health risk for the general population. The Guardian's reporting notes the move follows three earlier heatwaves this summer, each of which has strained infrastructure and public services across the peninsula.
