A severe weather front is set to sweep across Italy between Thursday and Friday, bringing intense rainfall, potential cloudbursts, gale-force winds, and rough seas.
Meteorological models indicate that a deep trough will form over the Iberian Peninsula, driven by a collision between cold polar air and warm, humid subtropical currents. According to preliminary data, the system will feature two distinct vortices, with one crossing the Mediterranean and generating an estimated minimum pressure of 985 hPa over northern regions by Friday.
The incoming disturbance follows a variable start to the week. Regional forecasting models show that after a brief, partial lull in precipitation through Wednesday, November 11, the weather pattern will escalate sharply by Thursday, November 12, as southern winds push active storm cells across the peninsula. The week from Monday, November 9 to Sunday, November 15 features disturbances returning at intervals with rains, thunderstorms, and progressively stronger southern winds, alongside new snowfalls on the Alps with rising snow levels during milder passages. Monday, November 9 brings weak, isolated rains early on to Liguria, lower Piedmont, and upper Tuscany, with afternoon precipitation growing more frequent in the Northwest and northern Tuscany, and evening reaches into western Emilia and parts of the Veneto.
Maximum temperatures on Monday hover at 10-14°C in cloudier, rainier northern zones, reaching up to 15°C in partly sunny northeastern sectors, 13-17°C in the center, and 18-21°C in the south.
Tuesday, November 10 sees the disturbance focus on the center, Sardinia, and parts of the north, bringing showers and thunderstorms to Liguria and the central Tyrrhenian coastal areas, rain to sectors of Emilia-Romagna, the Veneto, and Friuli Venezia Giulia, and inland extensions from Tuscany and Lazio to Campania, with accumulations around 5-15 millimeters in several affected sectors.
Wednesday, November 11 brings only a partial truce with discontinuous precipitation before cloud cover and northwest rain increase by evening.
Progression of the Storm Front
The disturbance kicks off on Thursday morning with scattered showers and thunderstorms striking the Northwest and Sardinia. By afternoon and evening, the severe weather will expand to encompass the rest of the northern regions and the central Tyrrhenian coast.
Meanwhile, the extreme south and the middle-to-lower Adriatic coasts will remain relatively sheltered—the former due to its geographical distance from the primary trough, and the latter because it sits downwind of the prevailing southwesterly Libeccio winds.
Conditions shift on Friday as the heavy weather continues to hammer the central and southern Tyrrhenian zones alongside large portions of the North. The extreme Northwest will begin to see initial clearings, while the system’s core pressure minimum centers over northern Italy.
Forecasters note that daytime maximum temperatures will remain above average across most central and southern regions, supported by strong Scirocco winds and a pronounced föhn effect pushing readings higher, whereas the Northwest will stay below seasonal averages on Thursday.
Rainfall Peaks Exceed 250 Mm in Liguria and Tuscany
Mathematical projections highlight severe accumulation risks for specific localized areas. Central-eastern Liguria faces total precipitation peaks exceeding 250 millimeters between Genoa and La Spezia. Similar volumes are expected across northern Tuscany and the western Emilian Apennines, where cumulative totals will surpass 200 mm with localized peaks also reaching 250 mm. Friuli is forecasted to receive between 150 and 200 mm of intense rainfall.
These regions face elevated risks of localized flooding and rapid surface runoff. Because this forecast looks three to four days ahead, meteorologists caution that exact trajectories and accumulation totals remain subject to minor adjustments.
Temperatures Vary Across the Country Through Friday
The meteorological divide across the country will be stark. On Thursday, temperatures will sit below average in the Northwest, hover near seasonal norms in the Northeast, and climb above average from Emilia-Romagna southward. Peak values are expected to touch 25°C across eastern Sardinia, eastern Sicily, and the middle-to-lower Adriatic sector, while Friuli Venezia Giulia expects maximums of roughly 10-13°C in the plains and 12-14°C on the coast.
By Friday, above-average warmth will persist across the central and southern regions, though temperatures over Sardinia are projected to drop. As the active phase of the front clears, authorities and residents in the most exposed watersheds remain on alert for potential disruptions.
