The Met Office has issued a red weather warning as Storm Eowyn heads towards the island, bringing winds of up to 160km/h which "could put lives at risk".
Parts of the UK could be severely affected on Friday and a curfew may be necessary as the country is battered by very strong winds, torrential rain and heavy snow.
The United Kingdom and Ireland are bracing for what the media is calling the "storm of the century", with forecasters saying they have never seen anything like it.
Fears of this storm are so great that schools in Northern Ireland will all close for tomorrow, according to Education Secretary Paul Givan.
Storm 'Eowyn' could also affect flights and train movements, with rail operator Network Rail warning that it is expected to experience the "strongest winds in a decade", while workers have been told to avoid travelling to parts of the north of the UK.
Tornadoes could also hit some parts of the country, ahead of Storm 'Eowyn'.
And Irish forecasters have activated a country-wide red weather code for storms exceeding 120km/h.
At the same time, they predict that winds could reach up to 220 km/h on the west coast of Ireland and up to 175 km/h in the Western Isles of Scotland. (A2 Televizion)
