Overview
- Northern and central regions face a wet Sunday with an orange alert in Liguria and the Emilian Apennines, while snow is confined mostly above 1,800–2,000 meters.
- Forecasts flag particularly intense rainfall in Liguria, with daily totals possibly exceeding 80 mm in central‑western areas and 40–60 mm between southern Piedmont and northern Lombardy.
- A Mediterranean vortex is expected between Tuesday and Wednesday to shift heavier rain toward the Centre and South after the early‑week disturbances.
- From Thursday 20 November, forecasters expect an Arctic‑maritime air mass to drive temperatures well below seasonal averages across much of the North and Centre.
- The incoming flow through the Rhône could help trigger a Tyrrhenian low that enhances precipitation and brings snow to much lower elevations by 22–23 November, potentially even locally on northern plains.
