Met Eireann has issued an Orange Alert wind warning for Donegal, Connacht and Munster.
An Atlantic storm depression is forecast to track to the northwest of the country tomorrow night and and Saturday.
There will be strong Southwest winds, gusting 100 to 130 km/h, with the Atlantic counties expected to be hardest hit.
The national weather agency is also predicting frequent heavy showers, some thundery, with sleet and snow for a time mainly on higher ground.
There is a high risk of flooding in coastal areas, due to the combination of very high spring tides, extremely high waves.
The M4 weather buoy, located off the Donegal coast, recorded a new maximum individual wave height of 23.4 metres at 3pm last Sunday, during the weekend storm.
This figure easily surpasses the previous record of 20.4 metres at the same location in December 2011, according to Met Eireann.
Donegal County Council has estimated that it will cost well over €1m to repair damage caused by the ferocious storms and extensive flooding that hit the county earlier this month. This does not include the cost of damage to privately owned homes, businesses and lands.
