Italy – 1 Missing After Rivers Overflow in Piedmont

Several rivers have overflowed in the northwestern region of Piedmont, Italy, after 3 days of rain. Rainfall levels have exceeded those of November 1994 which caused devastating flooding and the deaths of over 40 people.

Parts of Turin, the region’s capital, have recorded over 100 mm of rain in the last 24 hours, while other areas have seen over 200 mm.

Heavy rain has also affected parts of neighbouring Liguria, where one person was swept away by the overflowing Roia river.

ANSA, the Italian news agency, report that a man was missing after he fell into the Pellice river after a road gave way near Turin.

The Po River overflowed in a stretch between Cuneo and Turin, flooding the village of Cardè.

Parts of the city of Asti have been flooded after the Tanaro river broke its banks in several places. The Tanaro is also threatening to overflow in Masio and the Bormida rivers in the city of Alessandria.

Local media say that around 400 people have evacuated their homes. Italy’s Fire Service reports that it has carried out evacuations in several areas, including Bagnasco, Priola, and Volvera. It has also been assisting people in flood hit areas of Turin, including Pinerolo and Chivasso.

Premier Matteo Renzi said after a visit to the regional civil protection headquarters in Turin said the government will act “immediately” to address the flood emergency in Piedmont. “It is fundamental that in the coming hours the government moves immediately to help start assessing the damage and the aid the population needs”, he said.
