A separate status yellow warning has been issued for inland counties - Carlow, Kildare, Kilkenny, Laois, Longford, Offaly, Westmeath, Cavan, Monaghan, Leitrim, Roscommon, Limerick and Tipperary.
That warning is in effect from 11pm tomorrow until 9am on Friday.
Met Éireann meteorologist Joanna Donnelly explained: "This is a very serious weather event - although winds will be strongest at the coast, they will also be strong inland too, with gusts of up to 110km/h inland and up to 130km/h at the coasts.
"I would advise anyone getting up on Friday morning and starting a commute to be aware of the potential for fallen debris on the roads."
