A section of Clancy Strand along the River Shannon quayside in Limerick city flooded at high tide this evening.
The roadway located at the city's famous Treaty Stone remains closed off after the city fire brigade attended the scene earlier.
Five private residents are located along the vulnerable section of the quayside, and the waters were up to their front doors at one stage.
The flooding resulted from high tides accompanied by strong winds this afternoon with the river waters breaching the quayside shortly after 5pm.
A section of O’Callaghan Strand was also flooded for a short time at the same time, but that has now receded and the road is open.
Cork City Council advised there was a risk of flooding due to a period of high spring tides today and tomorrow.
