Italy sets new European 12-hour rainfall record

Italy sets new European 12-hour rainfall record

A severe storm stalled over NW Italy on October 4, 2021, dumping record-breaking rain and causing floods and landslides. In addition, the storm produced more than half a million lightning strikes within 48 hours.

The day started with 496 mm (19.5 inches) of rain in just 6 hours registered in Cairo Montenotte, Province of Savona, Liguria, breaking the country's 6-hour rainfall record of 472 mm (18.6 inches) set in 2011.1

In just 12 hours, the same storm system dropped 740.6 mm (29.1 inches) of rain in Rossiglione, 13 km (22 miles) E of Cairo Montenotte, in the Province of Genova, Liguria, setting a new European 12-hour rainfall record.

That's more than half of the average rainfall the region gets in a year -- 1 270 mm (50 inches).

Agenzia Regionale Protezione Ambiente Ligure (ARPAL) reported 1-hour rainfall totals of 145.2 mm (5.7 inches) in Cairo Montenotte, 178.2 mm (7 inches) in Urbe and 181 mm (7.1 inches) in Vicomorasso - a new national record. Furthermore, figures from ARPAL show the station at Rossiglione recorded more than 900 mm (35.4 inches) of rain in 24 hours.2

All that rain caused numerous rivers to overflow and produced traffic-disrupting landslides.

While authorities said they responded to many calls for help, including rescue operations, there are no reports of casualties.
