Motorists and householders have been warned of the risk of flooding in southern and eastern areas due to high spring tides.
The greatest risk is in Cork where high tides are predicted for this evening as well as on Thursday and Friday.
High tides are forecast between 7.30pm and 9pm tonight and from 8am and 9.30am tomorrow.
Tides are also expected to reach higher than normal water levels tomorrow evening from 7pm and again on both Friday morning and evening.
Cork Co Council’s severe weather analysis team urged the public to be aware of the likelihood of high tides with the greatest water heights expected in the south and east of the county.
The greatest impact of the high tides is expected to be felt by motorists due to the likelihood of floods on low lying roads, particularly in parts of Cork city and Cork harbour.
Residents and traders in low-lying properties have been urged to take all necessary precautions.
However, it is expected that the primary impact of the high tides will be spot-flooding on low-lying roads during the peak morning and evening rush hours.
Gardaí have urged motorists to allow extra time for journeys and not to park cars in low-lying areas at risk of tidal flooding.
Cork is currently the focus of a €140m flood protection scheme devised by the Office of Public Works (OPW).
The scheme was devised after the combination of torrential rainfall and high tides left the city facing its worst flooding in over 800 years in 2009.
An estimated €100m worth of damage was caused by those floods eight years ago.
However, Cork has been hit by less severe flooding four times since 2009.
Major flood protection plans are also underway for Skibbereen and Bandon in west Cork.
