A clean-up operation has begun in Killarney, Co Kerry, this morning, Friday, after “unprecedented” flash flooding overwhelmed much of the town and surrounding areas.
The heavy downpours led to the closure of major roads in and around Killarney, while a number of vehicles that became stuck had to be removed by the fire service.
The N71 Muckross Road, the main tourist route to Killarney National Park, was flooded, as was the N22 Cork to Killarney road at Pike Hill.
Homes in New Street, as well as domestic garages and houses in Fossa outside Killarney, were affected, with gutters and downpipes overwhelmed.
Fire Service and gardaí worked to clear the roads of traffic, while the Civil Defence was called in to deliver sandbags.
Water was pumped from a number of areas, including the railway bridge on Park Road and Woodlawn Cross.

Local councillors for the area said homes and businesses saw floodwater come through their doors, “damaging property and possessions in a matter of minutes”.
The mayor of Killarney, John O’Donoghue, described it as the worst flooding in a lifetime.
“Killarney got lashed with rain,” he said.
Other parts of Kerry remained dry, he noted.
“The whole town was submerged under water to a great extent,” Councillor John O’Donoghue of the Kerry Independent Alliance said.
Heavy rain began around 5pm, but the worst of the downpour occurred in the single hour between 7pm and 8pm, with around 30mm recorded at a weather station outside the town.
“We had no indication. There was nothing to indicate this was coming. Effectively the skies opened,” said Paul Neary, director of services with Kerry County Council.
A full assessment was being carried out and lessons would be taken on board.
Local councillor Niall Kelleher said it was a “very difficult night for Killarney”.
"The floodwaters have thankfully now receded, and roads around Killarney have cleared, but for many families and businesses the impact of what happened tonight will remain long after the water is gone," he said in a statement on social media.
"My thoughts are especially with those who watched flood water come through the doors of their homes and businesses, damaging property and possessions in a matter of minutes.
"It must have been an incredibly frightening and helpless experience, and [on Friday] morning many people will be facing an immense clean-up," Mr Kelleher added.
The former town mayor said work will now begin to assess the damage and support those affected.
"Kerry County Council will be assessing the number of properties impacted over the coming days, and I will be following up urgently on what national financial assistance and other supports can be made available to affected households and businesses," he said.
The weather station at Muckross House recorded 57mm of rain in under four hours, which was equivalent to rainfall associated with a red-level warning.
The drainage system was overwhelmed in places. Leaves and twigs that had built up over the dry summer were washed down and caused blockages. However, council crews managed to clear the system and, as soon as the rainfall stopped, the drainage system worked, he said.
High Street business owner Johnny McGuire said he experienced an “apocalyptic” storm and was assessing roof damage.
Mr McGuire, of Bricín restaurant and craft shop, paid tribute to the “fantastic emergency services” for their response.
There had been a particularly dry summer and the ground was rock hard. Killarney was in a hollow and “God nor man could have stopped it,” Mr McGuire, who is involved with the Killarney Chamber of Commerce and Tourism, said.
In a statement this morning, Kerry County Council said the town’s swimming pool and sports centre near Park Road, one of the worst-affected areas, will remain closed over the weekend.
“Kerry County Council crews are today assessing the impact of the flash flooding in Killarney last evening. Kerry County Council staff, the Kerry Fire Service and the Kerry Civil Defence mobilised to respond to the impact of the torrential rain from 7pm approximately.
“An estimated 57mm of rain fell in a four-hour period, with some 30mm in one hour alone, and this caused very significant flooding on roads throughout the town.
“This morning, Kerry County Council continues to liaise with properties impacted by the flooding and will provide any assistance required."
