As a major mop-up operation continues today following extensive floods caused by Storm Claudia, freezing temperatures are expected to bear down on the country for several days this week.
Met Éireann is warning that parts of the country will experience temperatures as low -1C, with extensive frost to hit tomorrow.
Meanwhile, families and businesses hit by Claudia's torrential rain and winds are counting the cost. The worst-hit counties include Carlow, Dublin, Offaly, Kilkenny, Laois and Wexford.
Thousands of homes and businesses were left without power after the storm.
The National Directorate for Fire and Emergency Management (NDFEM) held a meeting of local authorities, Government departments, State agencies and utility providers on Saturday to discuss the response to the heavy rain.
The NDFEM said impacts of the heavy rain continued over the weekend, with further flooding possible in Leinster and Munster as some rivers had not yet peaked. It said many grounds were 'already saturated' prior to the weekend rains, while many rivers were 'at capacity' resulting in some bursting their banks.
The Department of Social Protection has activated the flood relief Humanitarian Assistance Scheme for households affected, and the Department of Enterprise is liaising with local authorities about how the scheme can help businesses.
A woman in her 70s died after she got into difficulties in the sea off the Wicklow coast on Saturday afternoon. Gardaí were assisted by the Irish Coast Guard in a search and recovery in the Magherabeg beach area, which is close to Brittas Bay, at around 2pm.
The search involved the Wicklow and Greystones Coast Guard divisions, Coast Guard Search and Rescue Helicopter 116, and an all-weather lifeboat.
A Garda spokesperson said the woman's body was 'recovered from the water' at around 4pm, adding: '[Her] body has since been removed to the mortuary in St Columcille's Hospital in Loughlinstown, Co. Dublin.'
Another woman was rescued and is recovering in hospital. Elsewhere, a search is continuing off the Donegal coast for a missing Royal Navy crew member.
The Irish Coast Guard Maritime Rescue Sub Centre at Malin is coordinating the search along with the Irish Air Corps, the RNLI, the Royal Navy vessel and other agencies. The crew member was last seen at around 10.30pm on Friday when their boat was close to Tory Island.
The UK's Royal Navy said it's helping to find an individual from the Royal Fleet Auxiliary. Portarlington in Co. Laois was badly affected by the storms while one Wexford councillor described flooding as the 'frontline of climate change'.
Bridgetown in Co. Wexford had five feet of flooding, which resulted in homes and the Roches fish shop being badly affected. Blackwater and Courtown remained unpassable.
Aontú councillor Jim Codd said the situation was 'dire', adding: 'Even fire units couldn't make it through floods, so thankfully members of the Civil Defence waded in.' He also said that homes and businesses can no longer get insurance.
