Further status orange and yellow rain warnings have been issued for areas in the south and southeast of the country, including Cork which saw areas devasted by flooding following Storm Babet.
Over a month's worth of rainfall was recorded at a number of local Met Éireann stations.
Met Éireann has issued a status yellow rain warning due to come into effect from 6pm this evening covering Cork, as well as Clare, Kerry, Limerick, Tipperary and Galway, for a period of 24 hours.
The forecaster says heavy rain is expected with a chance of thunder, leading to localised flooding and difficult travel conditions.
With many areas in Cork still counting the costs of the severe flooding in areas such as Midleton and Glanmire, Cork County Council has said residents should be vigilant about the possibility of further flooding.
East Cork remains an area of "greatest concern" as up to 30mm of water rain is expected over the period, the council says, warning that the surface water drainage systems in the region have limited capacity and could become overwhelmed.
The local authority has warned people living in the region to be vigilant about the possibility of flooding again, and take all necessary precautions.
More than 7,000 sandbags have been distributed in the Midleton and East Cork area and residents are being advised to take all steps necessary to protect their property from the possibility of flooding.
Further sandbags will be distributed on a priority basis, the council has said.
Meanwhile, three counties, including Waterford, have been placed under an orange warning as Met Éireann says heavy rain with thundery downpours is expected next week.
The alert for rain will kick in at 4am on Monday and stay in place for 24 hours and covers Waterford, Kilkenny, and Wexford.
The national forecaster says the rain can lead to dangerous travel conditions, flooding and poor visibility.
A second status yellow rain warning will also come into effect for Carlow, Kildare, Laois, Longford, Offaly, Westmeath, Wicklow and Roscommon at 4 am on Monday.
Met Éireann has said localised flooding and difficult travel conditions are expected. It will stay in place until 4 am on Tuesday.
Main Street in Carrigaline will close from 9.30pm on Sunday evening until 8am on Monday morning, at which point it will be reviewed.
The government confirmed that funds were to be made available to the thousands affected by the impact of Storm Babet.
