Heavy rains across an already water-logged north-central Italy have flooded towns anew, burst riverbanks and forced limited evacuations. News reports said one man near Genoa was unaccounted for after his car got swept away.

The civil protection agency issued flood alerts Saturday for a large swath of Italy, from Genoa on the west coast to the Veneto on the east, with crews monitoring the Po River in particular. Bridges and roads were closed and authorities urged people to not drive.

Many of the hardest-hit regions are still recovering from flash floods over recent weeks that have killed several people.

The Coldiretti farmers' association said agricultural losses could number in the millions of euros from Saturday's rainfall alone, saying corn crops in Lombardy and Gavi vineyards in Piemonte were particularly damaged.
