Tens of thousands of homes and businesses have been left without power as Storm Barra wreaks havoc.
The storm arrived in Ireland early this morning with winds recorded up to 113km/h in some parts.
ESB Networks said almost 60,000 of their customers are without electricity in counties Donegal, Mayo, Roscommon, Westmeath, Galway, Clare, Limerick, Cork, Kerry, Tipperary, Waterford, Wexford, Wicklow, Kilkenny, Carlow, Dublin, Offaly, Cavan and Monaghan.
ESB have attributed most of the faults to "fallen trees on overhead lines."
"With the storm still crossing the country, more damage and interruptions to supply can be expected," they said. "ESB Networks reminds the public that if you come across fallen wires or damaged electricity network, never, ever touch or approach these as they are live and extremely dangerous. All internal resources are on alert and will be deployed to respond to all electricity outages once it is safe to do so. With a red weather warning in the southwest in effect until tonight, this may mean our crews may not be mobilised on the ground until the worst of the severe weather passes."
Most of the country is experiencing strong winds. Red Status Warnings have been issued for Clare, Cork and Kerry, with flooding reported in the latter two counties. Bus Éireann has cancelled its services in those counties.
