Bad weather incoming: Rain in Central-South Italy and first snowfalls on the Apennines.

A wave of bad weather is approaching Italy, bringing widespread rain to the Central-South and the first snowfalls in the Apennines. The National Meteorological Vigilance Bulletin of October 30, 2026 forecasts isolated to scattered precipitation, locally also in the form of showers or thunderstorms, across various peninsular regions and the major islands for the days of October 31 and November 1.

Rainfall amounts will generally be light, but may be moderate in some coastal areas of Apulia, Abruzzo, Molise, and on the Ionian sectors of Sicily and Calabria. Starting from Sunday, November 1, snow will fall above 1000-1200 meters in the Emilia-Romagna and Marche Apennines, and above 1100-1300 meters in the Abruzzo Apennines. Winds will be locally strong from the northeast, with very rough seas especially in the central-northern Adriatic.

The onset of severe weather is caused by a specific atmospheric configuration. An extensive area of high pressure (anticyclonic) positioned over central-western Europe is driving the descent of cold air masses of Arctic-continental origin toward the central Mediterranean. This flow is leading to a progressive destabilization of the atmosphere over the Italian Peninsula.

The process begins with the influx of this cold air, which favors the deepening of a low-pressure core over the seas south of Italy. This low-pressure system, in turn, intensifies instability, generating the expected clouds and precipitation. The severe weather phase is expected to last for several days, keeping temperatures about 3-5 degrees below seasonal averages, before gradually easing starting Wednesday, November 4th, with a rise in temperatures.
