The public are being urged to stay home tomorrow as a Red Weather Warning for Storm Éowyn comes into effect.
Met Éireann have issued Red Wind Warnings for the majority of the country which will come into effect tonight.
Schools, colleges and creches in impacted counties will close tomorrow, the National Emergency Coordination Group has announced.
On Newstalk Breakfast, Met Éireann meteorologist Joanna Donnelly said she cannot "emphasise enough" how dangerous conditions will be tomorrow.
"Coastal areas in the west are going to see the biggest impacts - but the difference between this storm and previous storms is it's sweeping right across the country," she said.
"Midland areas - particularly in north Connaught and north Leinster are going to see winds they haven't seen in a long, long time or indeed ever.
"It's an inland storm and it's coming right across the country."
There is a Nationwide Red Wind Warning with different applicable times.

Ms Donnelly said power outages, downed trees and flying objects are "likely" to occur as a result of Storm Éowyn.
"I can't emphasise enough how dangerous travelling conditions are," she said.
"If you can avoid travelling - the best thing you can tomorrow is stay home."
Dangerous driving conditions will continue even after the Red Weather Warning expires, Ms Donnelly said.
"The winds are looking like they’re going to be very significant," she said.
"I would emphasise [that when] you come out of a Red Warning, there are still very dangerous conditions on the roads because the impacts carry through.
"There will be trees on the road - the advice from Government is to stay home."
Outlook
Conditions are expected to ease tomorrow afternoon, but Ms Donnelly said we will still see "blustery" weather.
"It will probably be Friday night before we start to see calmer conditions," she said.
"Satruday conditions are easing up - we’ve still got lighter southerly winds but we have also got some wintery conditions coming through.
"Sleet and snow is likely - so we might have some impact from weather there."
Sunday will see "wet and rainy" weather, according to Ms Donnelly.
