Met Éireann has issued a new Status Orange weather warning for Leinster – with “deep lying snow remaining in places.”
The forecaster has said there is a “continuing potential for localized flooding due to the thaw.”
Frost and icy conditions are expected tonight and into Tuesday morning.
The forecaster said some river levels have risen by more than a metre in the past 24 hours because of snow melt.
It said Wicklow saw the highest levels of snowfall over the weekend.
Overnight some areas will experience temperatures of 0C to -3C where there is no cloud cover.
Most public transport will return to normal today.
Dublin Bus, Bus Éireann and the Luas are all running with a few interruptions.
Iarnród Éireann expects to be fully operational with the exception of two regional lines.
Nearly all services are operating today with some cancellations in the East. See https://t.co/KTHyBabX9Z for details @rtenews @TV3Ireland @Galwaybayfmnews @NewsonNS @OceanFmIreland @radiomidwest @Live95fmNews @Corks96FM @wlrfm @kclr96fm @eastcoastfmnews @kfmradio @LMFMRADIO

Spokesperson Barry Kenny explains the situation:
“Limerick Junction to Waterford and Limerick to Ballybrophy via Neenagh – we are hopeful of getting those open for the evening trains this evening,” he said.
“But apart from that all routes are operating.
“The Rosslare line which had been closed yesterday is back; the M3 Parway line is back and we will have a full service on all of those routes.”

Meanwhile, Irish Water has warned that further water restrictions could be on the way as reservoir levels are dangerously low.
10,0000 households around the country are without water this morning - with more than 20,000 others faced with restricted supplies.
‘Not a normal Monday’
The National Emergency Co-Ordination Group warned that today is ‘not a normal Monday’ in many areas.
Drivers are being warned that the roads remain hazardous as the big thaw from last week’s snow continues.
Be aware of the risk of thawing ice and slush build up at road sides. Visibility will be reduced as spray from vehicles is thrown onto the windscreen of your vehicle. Ensure that your windshield washer is full. Keep your lights clear of grime and dirt. #StormEmma pic.twitter.com/bwvJx2t1F0

Where possible schools, colleges of further ed & 3rd level institutions will re-open on Monday. However, decisions will be made by schools, colleges of further education and third level institutions on an individual basis depending on the circumstances in their area #StormEmma

It comes as many workplaces, schools and colleges are opening for the first time since the onset of Storm Emma.
However, schools in Wexford, west Wicklow and parts of Kildare are unlikely to re-open.
Decisions are being made on a case-by-case basis depending on the conditions in each area.
Parents from the schools affected will be notified.
