A man has been seriously injured and more than 184,000 homes and businesses left without power as Storm Amy battered the island of Ireland.
The storm also brought localised flooding, fallen trees, transport disruption and school closures in Northern Ireland.
The Republic of Ireland’s forecasting agency issued its highest-level wind warning in Co Donegal, where residents were were advised to shelter in place between 4pm and 6pm.
The red wind warning meant fallen trees, damage to power lines, dangerous travelling conditions, structural damage and wave overtopping.
Gardai said they were treating an incident where a man was seriously injured in Letterkenny, Co Donegal, shortly after 4.15pm as weather-related.
The Electricity Supply Board (ESB) said approximately 184,000 homes, farms and businesses across the Republic of Ireland were without power at 5.15pm.
The ESB said affected properties were predominantly in counties Galway, Mayo, Sligo, Roscommon, Leitrim, Cavan and Donegal.
It also warned that further power outages can be expected.
A spokesman said: “Crews will continue the restoration work for as long as possible this evening, but it is likely that the majority of customers will not have their power restored tonight due to the hazardous weather conditions and accessibility challenges.”
Schools across a large part of Northern Ireland were advised to close early as the high winds brought disruption.
No update has been provided on the number of homes without power in the region.

The Police Service of Northern Ireland said it may be necessary to close some routes and advised road users to consider if their journey is necessary, reduce speed, and “take extra care if you must travel”.

Clare joined the orange warning that was in place for Donegal, Galway, Leitrim, Mayo and Sligo, where Met Eireann warned of large waves and possible power outages.
Gusts of up to 130kph (80mph) were recorded at Malin Head in Co Donegal at 3pm, while consistent wind speeds of up to 89kph (55mph) were recorded elsewhere in the county at Finner Camp.
The most severe conditions were forecast for Co Donegal where a Red wind warning was put in place.
Keith Leonard, from the National Directorate for Fire and Emergency Management, told RTE’s News At One: “If I had one key message it would be for that period from 4 to 6 in Donegal this afternoon, to ask people to shelter in place for that amount of time and to be very careful on the roads before that warning comes into place and after it’s gone through.”
Mr Leonard said the storm will also feature “a lot of rainfall” and that fallen trees are likely to be an issue.
The conditions led to some flight cancellations in and out of the country’s airports.
At sea and along the coast, there is also a red warning from Loop Head to Rossan Point to Fair Head between 2pm and 8pm.
On Saturday there will be further yellow warnings, for wind in Dublin, Louth and Wicklow between 6am and noon; a combined wind and rain warning for Donegal, Leitrim and Sligo between midnight and noon; and a wind warning for Clare, Kerry, Galway and Mayo also between midnight and noon.
