Some of the areas left without electricity included Drogheda, Ennis, Limerick, Longford, Monaghan, Tipperary and Waterford.
Owen Sherlock of Met Éireann said winds reached speeds of up to 130km/h, which brought down power lines and trees.
Gardaí have warned motorists of dangerous driving conditions in many areas.
There are reports of debris and fallen trees in many parts of the country including; Dublin, Meath, Laois, Kilkenny, Cavan and Galway.
Met Éireann has said that while winds have eased, those travelling home for Christmas should take extra time for their journeys.
Elsewhere, high winds have disrupted road travel in Northern Ireland and fallen trees have blocked roads in Armagh and Down.
