Further heavy rain, along with a drop in temperature are in store for the country.
Met Eireann has issued a yellow weather warning for nine counties, that will run on for at least part of today.
Between 25 to 35mm of rain is expected in Dublin, Carlow, Kilkenny, Wexford and Wicklow. However, the heavy rainfall should turn to more showery weather later today.
Temperatures will remain between 6 and 8 degrees in the city.
The incessant rain led to warnings of flash flooding and the threat that more families will be evacuated from their homes.
The army again maintained a presence in south Co Clare, where the flooding is so severe that it is impossible to identify where the banks of the River Shannon used to be.
In Athlone the waters had increased by 2cm, leaving levels just 5cm off the record of 2009.
Banagher, Co Offaly, saw an increase of 10cm, while in Limerick they increased by 8cm.
The River Suir also rose yesterday and is likely to have a devastating effect on Clonmel, Co Tipperary.
The storms are predicted to rage for another three weeks.
More than 40 families there have been issued with precautionary evacuation notices with heavy rainfall expected to have a severe impact on parts of the town.
Kilkenny County Council warned motorists of a high chance of flash flooding in the county today, making driving conditions treacherous.
Cork received some consolation with the news that the ESB would not be increasing the discharge of water through the Inniscarra Dam.
However, Limerick and Clare were concerned as the ESB announced it was increasing the flow of water through Parteen Weir to 470 cubic meters per second.
In 2009, this figure reached 500 cubic meters per second and had a devastating effect to homes and businesses downstream. Now the ESB says that further increases are likely.
The ESB was also working last night to restore power to almost 2,000 customers who were cut from their supply.
Residents of Donabate, Swords and Malahide were left without power due to a fault but most had their power restored by 8.30pm.
In Cork, more than 1,600 people on the north side of the city were without electricity yesterday.
The rain also had a severe effect on travel - with many road closures in areas worst affected.
Meanwhile, a number of roads in Tipperary near Nenagh, Thurles and north as far as Westmeath remained closed last night.
A road in Galway that had previously been used to divert traffic away from major floods was under water for the first time since 1995.
