Cathal Nolan, from Ireland's Weather Channel, said the bad weather will continue for a number of days with further weather warnings expected.
He said there was a possibility of some "potentially quite significant coastal flooding" in parts of Cork on Saturday, with the morning and evening high tides of particular concern for Cork city and Bantry.
