"In the next few hours a low-pressure area arriving from the Atlantic will hit Sardinia before extending across southern regions during the day tomorrow, with rain and snowfall at low altitude and stronger winds," the warning said. Rain and snow were forecast in Basilicata, Calabria and Sicily in particular.
The civil protection department also issued a yellow warning for localised hydrogeological and hydraulic risk in Sicily, Calabria, Molise, much of Puglia and parts of Abruzzo. Central and southern regions have born the brunt of the recent cold snap, with temperatures dipping to -18 degrees Celsius in some places. Schools remained closed on Monday in dozens of municipalities in the central Abruzzo region including the coastal city of Pescara due to heavy snowfall.
