Overview
- Rivers swelled in Lazio as the Tiber in Rome topped 7 meters with riverbanks and cycleways closed, the Aniene overflowed near Tivoli, and evacuations and damage were reported in the Cassinate along with fallen trees in Rome and the Marche.
- Snow reached unusually low altitudes and some plains, with accumulations in Romagna and flakes reported across Emilia‑Romagna, Tuscany, Marche and Umbria, while Trieste saw first snow with worsening conditions expected.
- Meteorological services forecast the peak of the cold and low‑quota snow between January 6 and 7, with further instability over central regions and showers moving through parts of the South.
- Winds strengthened widely, including gale‑force bora at Trieste that could touch 100 km/h, as forecasts flagged very rough to agitated seas especially over the Ionian and southern Adriatic basins.
- Temperatures dropped sharply to about −9 °C in Alpine areas and near −3 to −5 °C in Milan and Turin, contrasted by highs near 20 °C in parts of Sicily; separate ENEA projections warn of more frequent intense precipitation events through 2100, particularly over the Alps.
