Met Éireann has forecast temperatures as low as -5 degrees in some areas tonight with snowshowers over Munster, east Leinster and parts of Ulster.
Tonight will be colder than last night and there will be widespread frost, forecaster Evelyn Blackburn said.
Bad weather led to further disruption for travellers today as snow and freezing temperatures spread across Europe.
Continuing snowfall and freezing temperatures caused further transport chaos in Britain and further afield. Earlier today parts of Kerry and Cork were experiencing problems due to snow and icy conditions.
Dublin City Council will have its gritters out on the roads overnight, with routes viewable here.

Heavy showers of sleet and snow fell in Cork in the early hours of this morning, causing traffic disruption in parts of the county.

Age Action Ireland has called on the public to stay in contact with their older neighbours and for people to take steps to protect themselves and ensure they remain warm in their homes during the current cold spell. “Cold weather can kill and does kill in Ireland, making the winter a particularly challenging period for older people in particular” Age Action spokesman Eamon Timmins said. “Snow and ice make that challenge even greater as many older people may not be able to get out to buy food, fuel or medical supplies.”
With parts of Ireland experiencing snowfalls in recent days and more snow and icy conditions forecast for the coming days, Mr Timmins called for vigilance.
"If there is an older person living in your neighbourhood we would encourage you to call or phone them to check if they need anything," Mr Timmins said.
Met Éireann has said that outbreaks of rain, sleet and snow affecting southwestern areas will die out in Ireland this morning but will return by evening. Wintry showers will continue in the east and north, falling as snow on higher ground.
