Eight and a half thousand households are waking up without power this morning after a stormy night across the country.
ESB Networks are reporting faults in Sligo, Galway, Cavan, Dublin, Tipperary, Limerick, Wexford, Waterford and Cork.
Spokesperson for ESB, Bevin Cody says the company hopes to have power restored to all customers by later today:
Gardai are also advising motorists to drive with extreme caution this morning as debris may be present on roads.
One man had to be taken to hospital last night after a tree fell on his car in north County Dublin.
The severe weather has caused travel disruption.
Some Irish Ferries and Stena Line sailings between Ireland and the UK are cancelled.
Passengers should check with their travel companies for exact information.
Meanwhile, bus transfers remain in place on the train route between Limerick and Ennis and also between Rosslare and Enniscorthy, because of flooding.
All other routes are operating.
