Storm Frank will rumble on today, bringing more high winds and heavy rain. Water levels in some parts of the country will reach their highest points since the disastrous floods of 2009.
Met Eireann forecaster Pat Clarke said that the capital could expect high winds and wintry showers.
"There is a yellow weather warning in place for Dublin, so the winds will be 50 to 60kmh, perhaps gusting at 90 to 100kmh.
"There will be heavy rain too and it might ease in the morning before it picks up again. The storm won't fully blow itself out until late in the afternoon.
"It will be cold then at night, with wintry showers and a bit of frost," Mr Clarke added.
Ferry operators Stena Line and Irish Ferries cancelled sailings from Dublin yesterday and urged those planning to travel to check with the transport companies to make sure their journeys were still going ahead.
Elsewhere, Storm Frank has seen water in the Shannon region continue to rise in recent days.
OPW engineer Jim Casey said that conditions in Athlone were also likely to deteriorate in the coming days.
"All levels on the Shannon catchment continue to rise," he said.
"There is an ongoing risk to Athlone ... I would say that we still remain in a severe flood situation, especially in the Shannon catchment. All ongoing flood defence efforts, such as pumping, will have to continue for some time yet."
It comes as the ESB warned that further torrential rainfall of more than 40mm would see water discharges increased at the Parteen Weir upstream of Limerick city - with inevitable consequences for flooding in Limerick and Clare.
Gardai and the Road Safety Authority have advised motorists to take extra care when travelling.
Met Eireann said New Year's Eve would be cold and frosty in Dublin city.
