Storm Arwen swept in over parts of the north of the country on Friday night, however the majority of its power seems to have been felt across the Irish Sea, battering much of Scotland and the north of England.
Gusts of almost 100mph (160kmph) were recorded in parts of the UK, damaging homes and streets. The UK's Met Office said speeds hit 98mph at Brizlee Wood in Northumberland.
Met Éireann had issued a yellow wind warning for counties Donegal, Mayo and Sligo, however that warning has since expired. A yellow wind warning issued by the UK Met Office will remain in place for the six counties in the North until 6pm on Saturday.
In parts of Britain, trees were uprooted, walls and roofs blown down and lorries were stuck as snow closed the M62 in the north of England.
Train services were cancelled in many areas, with a barn blown on to the line near Falkirk one of the many incidents reported in Scotland.
People were advised to only travel if absolutely necessary, and the UK Met Office described gusts overnight as “damaging” and having affected “a wide swathe of the United Kingdom”.
