Authorities were searching for 16 people missing in Piedmont region, most of them travelling in cars in the Col de Tende high mountain pass between France and Italy, according to civil protection authorities.
They include two people from Germany driving with their grandchildren – aged 11 and six – and a pair of brothers returning from France.Unrelenting rainfall overnight hit levels not seen since 1958 in northern Italy’s Piedmont region, where 630mm (24.8 inches) of rain fell in 24 hours, according to the Italian civil protection agency.
Two brothers were swept away by floodwaters while they were tending animals near the French border. One brother managed to grab onto a tree and was saved, while authorities were searching on the French side for the other brother.
Eleven campers were saved in Vercelli province, where floodwaters hit a 20-year high.
Alpine rescue squads evacuated by foot seven people who were in houses cut off by flooding at Terme di Valdieri; some had to be carried on stretchers due to the muddy conditions and accumulation of detritus.
