Overview
- Two Atlantic-driven cyclonic vortices are producing persistent rain, thunderstorms and strong winds over Sardinia, Sicily and much of the south this weekend.
- Civil Protection issued yellow alerts for Lazio, Sardinia, Campania, Basilicata, Puglia, Calabria and Sicily, with the Air Force warning of “intense phenomena” over Sicily, Ionian Calabria and Puglia.
- Local downpours could exceed 100 liters per square meter in hours, raising a concrete risk of flash floods on small basins and urban drainage.
- Northern regions remain largely dry and sunny with chilly nights and morning fog, creating a pronounced north–south weather divide.
- Conditions are forecast to improve from Monday, with subtropical high pressure bringing milder temperatures—up to 22–25°C on Sardinia and Sicily—before models hint at renewed instability later in November.
