Northern Ireland Electricity (NIE) has brought in 350 additional engineers from across the UK and Europe to assist local teams in repairing damage.

On the outskirts of rural towns, large trees that collapsed under the weight of the storm still litter the side of many country roads.

Those in the Republic of Ireland are also still feeling the effects, with 56,000 properties still without power after about 750,000 were cut off during the peak of the disruption.

BBC News NI has been looking at two areas badly affected by record-breaking winds and the subsequent clean-up operation.

The presence of maintenance workers trying to restore power lines or clean up debris is still a common sight, but scars left by Storm Éowyn are currently dominating one structure that towers over the skyline of Dungannon.

Scaffolding blankets the 150-year-old St Patrick’s Church on the edge of the town centre.

CCTV footage from the grounds of the Catholic church on the morning of the storm shows huge roof slates falling from more than 100ft.

As a result, the church remains closed and is undergoing extensive repair work.

“Thank God nobody was hurt or injured by falling debris; we’ve been lucky in that respect,” said parish priest Dean Donaghy.

The church dates back to 1867, and much of the wind damage relates to the ridge section in the upper part of the external roof.

“Some of the old decorative pieces from that section have also come off, and they’re quite large, about four feet high and five feet long, so that’s extremely dangerous,” Dean Donaghy said.

As the storm passed, one of the local parishioners went into the church to assess the internal damage.

They captured footage on their phone of a steady stream of water trickling down some of the large pillars that support the roof of the church.

Dean Donaghy added: “Unfortunately, some of the roof has been punctured and fractured, which has led to some water getting through, and certainly when there was a lot of rain earlier in the week, there was some water damage.”

The church is not open this weekend as a result of the storm damage, and people are being signposted to neighbouring parishes for alternative mass times.

“We’ll just have to wait and see how long the temporary patching work will take to make the building usable again,” he said.

Staffan Lindeman is one of 22 engineers from Finland who arrived in County Fermanagh on Tuesday to help fix power lines.

He expects to be here for the next 10 to 14 days.

He told BBC News NI that he has previously repaired storm damage in Norway and Sweden, but Northern Ireland is the furthest he has travelled to help.

He said the damage was “pretty normal in our standards”.

“We have big trees also coming down in storms, so this is usual stuff for us.”

Tree surgeons have also been drafted in to help cut fallen trees and provide access to fallen power lines and damaged equipment.

Mr Lindeman said he and his colleagues have enjoyed the hospitality and camaraderie of the local teams.

“It’s been great; I love it, the people, everything; everything is nice.

“The cooperation with NIE is fantastic; everything is top notch.”

Having fixed one fault, he collected more equipment that had been flown in from Finland and then headed out to the next job.

One of the lines being repaired on Friday had been damaged by fallen trees in Florence Court Forest.

More than a dozen engineers and tree cutters from Northern Ireland, Scotland and Finland worked the entire day to reconnect two properties.

The scale of the storm damage means there is plenty of work still to do before supplies are fully restored.

Gardaí (Irish police) are also investigating a possible weather link to a serious road incident in Donegal, near the border with Northern Ireland.

It happened on the N14, north of Lifford, near Ballinalecky Cross, but conditions are so dangerous that Gardaí were still not been able to reach the scene on Friday afternoon.

They are also warning people not to travel unless absolutely necessary as there may be fallen trees across the country as well as fallen or damaged live electricity wires.

In Donegal alone, 87,000 households were left without electricity on Friday and it was only when the red warning had lapsed that engineers were able to begin assessing the extent of the damage.

ESB Networks described the storm as “record-breaking” and said it had never experienced so many power cuts in the country before with any extreme weather event.

It said there was extensive damage to electricity infrastructure but that their crews would only start restoring power when it was safe to do so.

“Given the predicted extent of the damage nationwide, we anticipate restoration will take a significant number of days,” ESB said.

Status red gale warnings have ended across the country but orange warnings remain in place.

A wind speed of 183kmh (114mph) brought by Storm Eowyn has been recorded in the Republic of Ireland, the fastest since records began, Irish forecaster Met Éireann said.

Met Éireann said a gust of 183kmh had been recorded at Mace Head, County Galway, at about 05:00 local time on Friday, just above the previous record high of 182kmh (113mph) set in January 1945 in Foynes, County Limerick.

It also reported the mean wind speed record of 131kmh (81mph) set in 1945 in Foynes has been broken during the storm, with up to 135kmh (84mph) at Mace Head at 04:00 local time.

Thousands without water

The water service Uisce Éireann is beginning restoration efforts as about 60,000 people are without water and a further 500,000 at risk due to Storm Éowyn.

They said that number is likely to increase over the course of the day as the widespread powercuts continue at treatment plants and pumping stations, which will affect supplies.

Martin Homer and his family are one of many families in the Republic of Ireland that are staying in a crumbling home during Storm Éowyn.

Thousands of homes in counties like Donegal, Mayo, Clare and Limerick, are crumbling due to them being built with defective concrete blocks

Mr Homer said he was worried about the structural integrity of their house in County Donegal, which is scheduled to be demolished.

He said he was very worried after seeing parts of their exterior walls fall away due to the strong wings.

“It’s a horrendous situation to live in, we wouldn’t wish it on anyone, it’s something you have to live in to truly experience,” he told BBC News NI.

“We know it’s not just us and there are so many out there living this nightmare.

“We are all terrified, every crunch or crack we hear is leaving us all terrified.”

He appealed to anyone, like their family, currently living in a crumbling house to ensure both themselves and their loved ones are safe.
