Overview
- Initial bands of rain begin Friday with showers over Tuscany, Lazio and Campania, then expand Saturday alongside strong Libeccio gusts on the Ligurian and Tuscan coasts with a risk of storm surge.
- Sunday, January 4 is forecast as the peak as a deepening depression over the Italian seas intensifies rainfall, with the heaviest totals expected across Grossetano, Lazio, Umbria, Marche and Abruzzo and additional showers possible on the Gargano, Sardinia, Calabria and Campania.
- Abundant snowfall is expected along the Apennines generally above 1,500–1,600 meters, with snow levels projected to drop on Sunday to hill levels in parts of Marche and Umbria and locally to 100–300 meters on the northern Apennines in Romagna.
- Northern regions should stay largely stable and sunny yet turn markedly colder under an Arctic air influx, with Bora gusts on the upper Adriatic increasing the wind chill.
- Forecasts indicate a colder, unsettled start to next week with the potential for a new cyclone to reinforce strong winds and additional precipitation from Monday, January 5.
