There have been some delays to Irish Rail services on the Rosslare line due to high water levels but it is still passable between Gorey and Enniscorthy.

Mr Leonard said there had been a lot of surface water, with Laois particularly badly hit in that regard.
"I think we've gotten away without too much difficulty," he said. "Now there are a small number of premises, certainly in Wexford, businesses and dwellings, that have been flooded, but I think we're talking a handful at this stage, and we're still gathering information.
"Laois was badly hit in terms of surface flooding as well, and there's a lot of surface flooding, but generally speaking, I think the country got away without the worst effects of Storm Claudia."
In Co Laois, parts of Portarlington were under water after levels in the River Barrow peaked at around midnight last night.
Some roads and the People's Park in the town are flooded, but no properties were impacted by the flood water.

Senior Assistant Chief Fire Officer for Portarlington Anthony Tynan said the situation has improved considerably from yesterday, and that the work of the council and local fire services had prevented and homes and businesses from flooding.
Despite not being under a Status Orange warning, he said they were ready for the impact of heavy rain.
"We’ve had steady rainfall over the last three or four days and it's been a cumulative event rather than a single once off. For the last few days, the council’s severe weather assessment team has been meeting twice a day to see what's happening on the ground and make preparations".
Watch: River Dodder in Dublin swells after heavy rainfall

Gardaí have appealed to road users not to be complacent this afternoon and evening, even though the worst of the weather has passed; but to "expect the unexpected".
Superintendent Liam Geraghty from the Garda Press Office said the road network is "extremely wet and saturated" and that rural and less-travelled roads will be covered with leaves and debris, and possibly even trees that have fallen down.
He urged motorists to be cautious, slow down and leave plenty of time to brake.
Supt Geraghty also warned that the rain from the last 24 hours is still making its way down into water networks and drains and could still cause localised flooding.
