From early indications, it is not expected to be of the same scale as the surge which occurred at the beginning of the month.
The greatest risk is at Victoria Park in the Sydenham area of Belfast, the agency predicted.
A yellow warning for rain is in place for counties Antrim, Armagh and Down on Friday and Saturday.
The warning continues on Sunday when it also covers counties Fermanagh, Tyrone and Derry.
Pat Aldridge, Rivers Agency's Director of Engineering, said that the risk of a tidal surge coincides with high tides on Saturday.
"The most critical tide will be at 11.54am. In addition, there has been a lot of rainfall recently, leading to saturated ground and high river levels.
"Further rain is forecast and therefore there is a risk of river and surface water flooding, particularly if high flows coincide with high tides," he added.
The Rivers Agency is liaising with the UK Coastal Monitoring & Forecasting (UKCMF) Service and analysing the emerging data as it is received.
"At this stage predictions are lower than what was experienced during the events in the new year but nonetheless are giving some cause for concern," Mr Aldridge continued.
"As the situation develops Rivers Agency, in conjunction with other responders, will decide what precautionary measures are appropriate. These may include closing Victoria Park, and erecting the flood barrier at the Sydenham underpass. Sandbags will also be deployed as necessary.
"In the meantime, the public in coastal areas should be vigilant over the weekend and keep up to date with news bulletins and the nidirect website at www.nidirect.gov.uk/newsroom."
