More bodies were found on Thursday after almost every river flooded between Bologna and the north-east coast 115km (70 miles) away.
Some 280 landslides have taken place.
"It was a very bad 48 hours. Water and mud took over our whole village," said Roberta Lazzarini, 71.
Her home of Botteghino di Zocca, south of Bologna, was hit by a torrent on Wednesday. Streets, houses and gardens were inundated and Roberta said she was still scared.
"I've never seen anything like that here. We were stuck and didn't know what to do. I just hope it doesn't happen again."
