Met Éireann has issued two separate weather warnings for the weekend, with heavy rain and winds expected in parts of the country.
A status yellow wind warning is already in effect for Donegal, Galway and Mayo.
Forecasters say winds will reach mean speeds between 50 and 65 km/h at times, with gusts between 90 and 100km/h.
Winds are set to be strongest along coasts.
The warning came into effect at 8am, and is valid until 3am tomorrow morning.
Meanwhile, a separate status yellow rainfall warning will come into effect for Munster and Leinster at 6am tomorrow.

Heavy rain on Sunday is expected to see accumulations of 25 to 35 mm.
That warning will remain in effect until 6pm tomorrow.
Forecasters say Sunday is generally expected to be a cold and wet day for much of the country.
They say: "Rain will develop along southern coasts then push northwards, and become widespread.
"The rain will turn heavy in the afternoon and possibly turn wintry later as well, with some snow over the hills and mountains."
It comes as storm Freya is expected to bring heavy winds to part of the UK tomorrow and Monday.
Here, Met Éireann says the strongest winds from the storm will be off the south and east coast of the country.
