Meanwhile, high tide has passed in Cork city without any significant flooding after Cork City Council earlier warned that low-lying parts of the city centre may flood before and after high tide at around 9am.
The local authority said that the main impact of any flooding was expected to be on traffic.
A tidal surge, southerly winds, a low pressure area and a spring tide were expected to give rise to flood conditions.
The council also warned householders and the owners of businesses to take steps to protect their properties.
Driest January for up to 30 years
Meanwhile, new data from Met Éireann has revealed that parts of the country experienced their driest January in up to 30 years.
With dry settled weather and high pressure dominating for much of the period, the majority of places reported below half of their normal rainfall for the time of year.
Weather stations in Dublin and the east midlands reported their driest January in 11 years, with a few stations in the west and north reporting their driest January conditions in 20 years.
However, Claremorris in Co Mayo experienced particularly low amounts of rain, recording the driest opening month of the year in three decades - just 40% of its normal long-term average.
It was a mild month too, according to meteorologists, with the west, northwest and east experiencing the highest average temperatures.
Most places had the warmest January in five years, but Malin Head in Co Donegal was the exception, clocking the hottest January in ten years.
The highest daily temperature was recorded at Shannon Airport and Roche's Point on the 24 and 10 of January respectively, with both hitting 12.9C. The month's lowest air temperature was -5.7C at Fermoy on 3 January.
