After a peak gust of 160km per hour overnight, the Met Office said on its social media that Storm Isha is now moving away.
ADVERTISEMENTRain and high wind warnings have been issued across the UK on Monday as Storm Isha continues to hit the country.
The storm left more than 55,000 homes in the UK without power overnight, with strong gusts of wind and rainfall triggering more than 80 flood warnings.
Northern Ireland was worst affected by more than 45,000 power cuts, followed by the North West of England (8,000 cuts), Wales (3,000 cuts) and Cornwall with a few hundred, the BBC reported.
The storm brought peak gusts of up to 160 kilometres per hour.
A rare red alert has also been issued in Scotland for strong winds lasting more than an hour, particularly in the north. Scotland's rail operator suspended services on Sunday night and into Monday's rush hour.
Air traffic control restrictions have also been in place both in the UK and Ireland, leading to some flight cancellations.
Planes bound for several airports were diverted, including a flight from the Canary Islands to Dublin that ended up in Bordeaux, France.
Several major roads in Scotland and northern England have been closed due to wind, fallen trees or overturned lorries.
Many of them remained closed on Monday morning, according to Chief Superintendent Davy Beck of the Police Service of Northern Ireland.
"There is also a continued risk of significant debris on the road network as wind speeds remain high throughout Monday," he said.
The Met Office, the country's weather service, said on its social media that Storm Isha is now moving away.
"However, it remains windy this morning and a yellow warning is in place until midday. Expect some disruption on Monday morning".
UK has faced months of storms
Parts of Britain have been battered by a series of gusty and wet storms since autumn, which have downed trees, knocked out power and caused flooding in river valleys.
Isha is the ninth named storm since September.
In western Ireland, the counties of Donegal, Galway and Mayo were warned of extremely strong and potentially destructive gusts from Sunday afternoon into the morning.
The Irish Met Office issued yellow wind warnings, with a red gale warning for coastal areas in the north, advising people to stay away from the coast.
Airlines cancelled 102 flights in and out of Dublin Airport on Sunday.
The storm also forced more than 24 aborted landings, while 27 flights opted to divert to other airports, Dublin Airport said in a post on X.
