( CNN ) -- At least six people have died and several others are missing after rains triggered severe flooding in northern Italy , state-run news agency ANSA reported . Heavy rains continued to fall Thursday night in Milan and other spots across the southern European nation , according to the Servizio Meteorologico , Italy 's official weather agency . That includes an alert from the agency about intense , widespread rainfall -- potentially with strong wind gusts and hail -- in the regions of Calabria and Basilicata , as well as the eastern part of Sicily . Meanwhile , Monterosso al Mare -- between Genoa and Pisa on Italy 's northwest coast , in the Cinque Terre region of Liguria -- has been `` isolated , accessible only by sea '' because of earlier rains and floods , Mayor Angelo Betta told ANSA . So , too , is the nearby town of Vernazza , with even bulldozers and cranes still not able to reach it . That said , Betta reported some progress Thursday thanks to round-the-clock efforts by emergency workers and volunteers to clean up the town . One volunteer in that community died in the flood Wednesday . `` The situation is much better compared to yesterday , '' Betta said . Italy 's defense ministry noted Thursday on its website that 348 military personnel have deployed to the provinces of Massa Carrara and La Spezia to assist in the wake of flooding here . Three people were killed after a house collapsed in La Spezia , the news agency stated . ANSA also reported that prosecutors have opened a manslaughter investigation related to the deaths of two people from flood-related injuries in Aulla . Authorities are assessing whether their deaths had anything to do with faulty work that may have caused the Magra River to overflow . The weather has also caused major travel headaches throughout the region . A mudslide that trapped a truck driver , who was eventually freed , has caused the A12 highway in Liguria to be blocked since Tuesday . Train service in Liguria has been halted , too , due to mud and debris on the tracks . CNN 's Marilia Brochetto contributed to this report .
