Luas bosses have confirmed there won't be any trams today.
They met at noon to reassess when services would get back on track.
Both the Red and Green lines are out of action after a technical room at the Red Cow depot was damaged during Storm Ophelia yesterday.
In a statement on the company's web site, Transdev thanked commuters for their patience:
"Luas service will not resume on the Red and Green Lines today... They will resume tomorrow at 5.30am.
Hurricane Ophelia damaged the roof on the Red Cow depot yesterday at approximately 14:30
The roof is being repaired today - the firm contracted to repair the roof have estimated it will take the whole day.
The section of roof damaged is over what is known as technical rooms.
Within those rooms are Luas systems. Those systems, for example, assist with overhead power and the AVLS, which is the automatic vehicle location system.
These are necessary to run the Luas operation."
