Met Eireann’s red alert warning is in place in south and eastern parts of the country, with Wexford, Galway, Mayo, Clare, Cork, Kerry and Waterford getting the worst of the stormy weather.
The forecaster warned gales of up to 150 kmph are expected to ravage coastal areas and there is a danger that high seas could cause coastal flooding.
Damaging gusts of between 120kmph and 140kmph could batter the worst affected areas.
A less severe orange weather alert is in place for the rest of the country, with particularly high seas in the northwest.
Meanwhile, AA Roadwatch has warned drivers to take extra care on the roads and to be vigilant of fallen trees and other debris.
