Forecasters say the worst of Storm Ali should be over, but damage caused by this morning's strong winds is continuing to affect travel across Dublin.
The gusts have caused severe disruption to green line Luas services, with the majority of the line closed all day.
Much of the green line will remain closed tomorrow morning, as teams work to fix problems caused by this morning's high winds.
Services will only run between Broombridge and Dawson, and then Brides Glen to Balally until further notice.
Spokesperson Dervla Brophy says engineers need to free a section of the tram known as the panto-graph.
"That's the bit of the tram that connects the roof of the tram to the overhead power-lines", she explained.
