Turin sits at the foot of the Alps in northwestern Italy and receives around 850 mm (about 33 inches) of rain a year, with autumn typically the wettest season as Atlantic and Mediterranean moisture collides with the mountains nearby. The Po river, Italy’s longest, begins near the city and has a history of significant flooding during periods of sustained heavy autumn rain across the wider Alpine watershed, a risk that extends well beyond the city itself downstream. Intense, fast-building summer thunderstorms are a separate and more localized hazard, often producing hail given the region’s proximity to the mountains. Because both flood risks operate on such different timescales, radar is most useful for tracking the faster-moving summer storm side. Italy’s national radar network covers the Piedmont region.
