Storm Frank has caused havoc across the country as ferry sailings were cancelled, roads closed and a car was blown into the Shannon.
Around 5,000 homes were left without electricity earlier today. Affected homes were in Donegal, Mayo, Kerry, Cork, and the south-east.
ESB Networks crews are working to restore power but they are having to deal with the difficult weather conditions. The company had restored power to most people by this evening with just over 1,100 homes still without electricity.
Gale force winds and gusts led to extensive flooding and a partial breach of sandbag barriers in many parts of Athlone tonight.
Southerly winds brought floods into residential areas at the Strand and at Deerpark.
The Minister for the Environment Alan Kelly and the OPW Minister Simon Harris are both to visit Athlone tomorrow afternoon to meet with victims of the flooding who have been critical of the lack of government ministers in the flood areas of the midlands.
There was substantial flooding in Graignamanagh this evening in Kilkenny.

The heaviest rainfall is expected tonight along southern coastal counties such as Cork, Waterford and Wexford and possibly along the west coast.

Local authorities have warned the combination of high winds and heavy rain, as well as high tides, will lead to flooding in many areas.
Residents along the banks of the River Shannon, above and below the weir at Parteen, have been warned to expect higher water levels, adding to existing flooding problems.
The Irish Coast Guard has advised the public to stay away from coastal areas, as the storm will bring high seas and drive large waves ashore.
The Road Safety Authority has appealed to drivers to take extreme care if going out on the roads and to be aware that objects may be blown on to roadways and vehicles may be affected by cross winds.
IFA urges Taoiseach to intervene
The Irish Farmers' Association has called on the Taoiseach to intervene and instruct Bord na Móna to turn off dozens of water pumps that are sending thousands of gallons of water back into flooded parts of the river Shannon.
Tom Turley of the IFA national flood project committee said the move would ease flooding for landowners and residents in south Roscommon, Offaly and Galway in the next three days as Storm Frank floods the area again.
"It's time the Taoiseach got involved," Mr Turley said. "We haven't seen Mr Kenny in the flooded areas here - yet we have seen his counterpart out in the floods in the UK and among his people."
A spokesman for Enda Kenny denied the Taoiseach had not been in flooded areas: "The Taoiseach has in fact visited flooded areas in Mayo. He is fully abreast of the situation nationally and has been from the start," he said.
"His ministers have visited numerous locations affected at his instruction where they have heard at first hand the major challenges people are facing," the spokesman added.
