The search for Waterford man Vincent Wall (27), believed to have drowned in the river Tiber in Rome on Friday night, continues today.
Mr Wall, who was in Rome to attend a friend's wedding, is believed to have lost his balance and fallen into the Tiber at about 3am on Saturday morning.
The swollen river is at its highest level for 40 years following days of heavy rain in the Rome area.
Mr Wall was the second person feared drowned in the flooding. On Friday morning, a woman drowned when her car became stuck in a flooded underpass in the suburb of Monterotondo.
Last night emergency workers remained on high alert as the rain, which had granted a temporary reprieve yesterday afternoon, started up again, once more prompting fears that the Tiber might flood central Rome.
Meanwhile, emergency services in Belfast are today searching for a man seen entering the River Lagan in Belfast this morning.
Shortly after 3.00am the fire service received a report that a person had gone into the
water at Queens Bridge.
Police, the coastguard and the RNLI were involved in the search.
In Derry, a man was rescued from the River Foyle this morning. A rope and lifebuoy were thrown to him.
He was taken to hospital but is not seriously injured.
