A Status Orange snow-ice warning has been extended until 12 midday today for Leinster, Cavan, Monaghan, Cork, Tipperary and Waterford.
Met Éireann has warned that widespread lying snow and ice will continue to lead to hazardous conditions.
The forecaster has also said there will be a risk of localised flooding due to rising river levels and there will be areas of surface water pooling, adding that mountainous catchments and urban areas will be most affected.RTÉ
reports that a Status Yellow snow-ice warning is also in place for Connacht, Donegal, Clare, Kerry and Limerick, with Met Éireann saying lying snow and ice will continue to cause hazardous conditions
Although a thaw is underway, conditions remain treacherous in many places and there are warnings of potential flooding as heavy snow melts.
The Chairman of the National Emergency Co-Ordination Group, Sean Hogan, has said there are still very challenging conditions and while they are co-ordinating efforts to get the country back to normal, tomorrow "will not be a normal Monday for many areas".
Speaking at a briefing yesterday Mr Hogan said schools will make decisions on a "case by case basis" but said it is unlikely, in the areas worst affected like west Wicklow, north Kildare and Wexford, that it will be possible for schools to re-open on Monday.
Mr Hogan said the normal Monday commute will also be very different and where possible they are asking people to use public transport. Flooding
Employees and employers are being asked to stagger start and opening times for work to reduce peak volumes of commuter traffic and also to look at options of working from home.
Gardaí have said there has been some flooding in Cork at Morrison’s Island, Father Matthew Quay, South Terrace, Lapp’s Quay and Wandesford Quay.
At high tide just after 7am yesterday morning, tidal water spilled onto the quays in these areas.
Irish Water is appealing to all customers to conserve water usage.
10,500 people without water, mainly in Cork, Laois and Wexford with a smaller number affected in Kerry and Tipperary.
121,000 customers have had their water restrictioned in Galway, Kerry, Leitrim, Longford and Waterford.
More than 3,000 on boil water notices, with most of those in Aughrim Co Wicklow.
Due to critically low levels in the Carnes and Balloy reservoirs, and a high demand, a water outage will impacted 12,500 customers in East Meath yesterday afternoon.
Irish Water said there is an unprecedented demand due to people leaving taps running during the freezing weather and this is causing reservoir levels to drop.
CEO Jerry Grant said reservoirs in Belgard and Cookstown had also faced particularly strong demand, and so water supplies in parts of Dublin may have to be restricted.
They supply Tallaght, Clondalkin, Rathcoole and the south of Dublin city centre.
He stressed that priority would be given to ensure supplies to hospitals would not be be interrupted, if restrictions are introduced.
Overnight water restrictions were in place in parts of Longford, Westmeath, and Galway.

ESB Networks has said that power has been safely restored to almost all of the homes and businesses that lost power in Wexford during Storm Emma.
A small number of homes are still without power but crews will restore supply as early as possible today.
The Health and Safety Authority has urged caution for those returning to work after the storm.School
Bus Éireann school transport services will resume this morning, dependent on local road conditions and possible school closures.
Bus Éireann transport over 116,000 school children every day, operating 3,000 vehicles on 6,000 school routes.
Many of these services operate in rural areas, and on minor routes - and in certain parts of the country, these roads remain in a very poor condition or are impassable.
