Met Éireann has issued a country-wide Status Yellow wind warning for tonight and tomorrow that will see the entire island battered by extremely strong winds, with gusts of 110kmh.
The winds coupled with heavy rain, storm surges and spring tides are also expected to cause flooding in coastal areas.
The warning will go into effect at 9pm until midnight tomorrow. Additional warnings are expected to be updated later on today.
The Status Yellow coincides with a weather advisory warning of 'unseasonably wet and very windy weather' from 9pm tonight until 9pm Friday, "with further rainfall and wind warnings likely".
"Strong winds at times may result in unsafe conditions and some disruption, especially over high ground, lakes and sea areas.
"There is also a risk of flooding," according to the advisory.
Met Éireann forecaster Matthew Martin said the stormy conditions are due to a "big Atlantic storm depression" that is currently brewing off the west coast.
It is expected to churn up winds of 90kmh nationwide as well as gusts of 110kmh or higher in coastal areas.
The worst of the winds will hit tonight and continue overnight into tomorrow.
Coastal areas in the south and west will be at the greatest risk of coastal flooding, he told the Herald.
He also warned of heavy rain and the possibility of thunderstorms developing tomorrow as another band of rain spreads northwards throughout the day.
While it will remain mild with daytime highs of between 16C and 20C, the blustery conditions will continue on Friday with more scattered showers and strong gusts in coastal areas.
