A Status Yellow wind warning, which was in effect for Wexford, Wicklow, Dublin, Meath and Louth, expired at 1pm.
The National Directorate for Fire and Emergency Management (NDFEM) has said the entire country is vulnerable to flooding over the next 24 hours.
NDFEM National Director Keith Leonard said that there is a complex picture with onshore winds, high tides and heavy rainfall forecast.
Speaking on RTÉ's Morning Ireland, he said: "We're watching particularly the northeast, Louth, Cavan, Monaghan, Meath, the catchments all there are pretty much at bank full.
"So, any further rain there could lead to river flooding and obviously surface conditions [are] really difficult right across the country."
Local authorities are fully deployed, he said and "they're watching the river levels, particularly in those areas mentioned, really right along the east coast, where sandbags are needed, they'll be provided".
He said crews were also looking where there are "pinch points" and putting in temporary flood defences where necessary.
Mr Leonard said there should be sandbags for everybody who needs them and local authorities are working together to provide mutual support for any additional capacity that is required across the country.
"A key safety message for us, do not drive through flooded water and do not, particularly, drive down roads that have been closed.

"Unfortunately, it's been a continual theme throughout the last number of weeks where fire services and emergency services and coastguard have had to rescue people from cars.
"So, we're hoping that won't be repeated again today," Mr Leonard said.
Met Éireann Meteorologist Rebecca Cantwell said there the east coast will experience the worst of the weather and it is not going to take much rainfall for there to be flooding.
"The ground is still saturated, rivers are still so high and then we've got the winds as well picking up along the east coast. That's going to bring some coastal flooding with it as well, even if there isn't huge amounts of rain," she said.
She added that higher ground, such as the Comeragh Mountains and the Wicklow Mountains, will generally see the highest amount of rain.
In Northern Ireland, a Yellow rain and snow warning for Antrim, Armagh, Down, Fermanagh, Tyrone and Derry, is in effect until tonight.
The UK Met Office said that outbreaks of rain, hill snow and strong winds may bring some disruption to travel.
