Cork City Council has warned that the city centre is at significant risk of flooding tomorrow morning and has urged property owners to put flood defences in place.
The council's director of operations, David Joyce, has said flood assessment teams and consultation with Met Éireann confirmed that a "short, sharp, event" will take place over two hours in the early morning.
The areas affected are Morrisons Island, the South Mall, Oliver Plunkett Street and minor adjoining streets.
Drivers are also being asked not to park in those areas this evening
Mr Joyce told RTÉ's Morning Ireland that a high tide at 6.21am and a significant storm surge of up to three quarters of a metre are expected to flood the city centre.
He warned people to erect barriers to protect properties.
However, he said the event will be finished and cleaned up in times for shops to reopen tomorrow, so he said shoppers could still come into Cork city tomorrow.
Also today, Met Éireann issued Status Orange and Yellow wind warnings across Munster and Leinster.
Cork City Council has also warned that there will be road closures in the city centre tomorrow morning from 5.30am to at least 7.30am.
