Met Éireann has warned that any additional rainfall, particularly in southeastern, northeastern and eastern areas, could cause further river flooding today.
A Status Yellow rainfall warning for counties Carlow, Dublin, Kilkenny, Louth, Wexford, Wicklow and Waterford comes into effect at 9am.
The alert is valid until midnight.
The National Emergency Co-ordination Group urged the public to remain vigilant over the coming days, with the risk of flooding expected to continue into the long weekend.
Chairperson Keith Leonard said the group is preparing for another "difficult day" for many parts of the country.

Met Éireann said people in the affected counties could face localised or river flooding as well as difficult travel conditions due to already saturated grounds and bank-full river levels.
In Co Wexford, authorities remain on high alert following Storm Chandra.
They said today could prove critical and there are significant concerns about the rain that has been forecast to fall, particularly this afternoon.
Wexford County Council warned there is "a continued high risk for flooding for the Slaney, and particularly Enniscorthy town, right through the bank holiday weekend".
"Many rivers, including the Slaney are currently very full, so combined with continued heavy rains and drenched soils, this may create further accumulations of both surface and river water," it added.
Its teams, the council said, "remain vigilant, monitoring the river gauges to assess potential impacts in the county, and in particular for the recently flood-affected areas".
The council noted there was "an accumulated rainfall of 79.6mm" between 22 January and 28 January, addng repair work is "ongoing around the county, to damaged roads, pipes and manholes".
It urged residents and businesses in "the immediate flood risk areas around the Slaney in Enniscorthy and Bunclody" to remain vigiliant yesterday evening due to the "very high" risk of further flooding.
South Dublin County Council echoed advice from Wexford County Council, urging people to be aware that the risk of flooding persists due to high river levels and saturated ground.
"Crews are currently working on clean up, debris removal and flood protection preparation," it added.
The Road Safety Authority advised road users to "take care on the roads" following heavy rainfall this week.
A yellow rain warning is in effect for Northern Ireland until 6pm, with the UK Met Office warning spells of heavy rain could cause "some transport disruption and flooding in places".
A rapid study of Storm Chandra by climate scientists found it was the accumulation of rainfall over seven days, including on the day of the storm itself, that caused this week's flooding to be so devastating - not the actual amount of rainfall that fell during the storm itself.
