Italy puts nearly all major cities on highest heat alert

Italy is raising its heat warning to the highest red alert in nearly all major cities, with 19 already affected and 25 of 27 expected by Monday, as a North African subtropical anticyclone strengthens over the Mediterranean. Health officials urge residents to avoid direct sunlight and stay hydrated, warning of risks even for healthy and active people. The heatwave coincides with devastating wildfires across Greece, France, Portugal, and Spain.
