No Red or Green Line Luas services will operate tomorrow morning.
It's after a technical room in the Luas Depo in Clondalkin was damaged during Storm Ophelia this afternoon.
Transdev which operates the trams say all services will be postponed until further notice.
Luas will update passengers about services after a meeting at midday tomorrow.
A spokesperson said:
"It will take time to investigate the damage caused and time to repair. We are not able to give an estimate in relation to the time it will take. Luas will therefore not operate a service on Tuesday morning October 17th 2017. Luas will inform customers, media and the public about Luas services post a 12 noon meeting tomorrow."
Customers are advised to check Luas.ie and follow @luas on Twitter for updates.
