Chilly conditions, wintry showers due - Met Éireann
The winter chill is set to stay - with sub-zero temperatures due over the next few days.
Met Éireann said snow should be limited to the northern and western areas and higher ground, with forecaster David Rodgers warning the chilly conditions will continue. Temperatures in parts of Leinster will drop to -2C by night.
"Night-time temperatures in various parts of the country will be below zero," he said, but emphasised that this is not unusual for January.
"Showers could become more widespread on Wednesday, but they will retreat to more northerly and westerly areas after that."
He added that rainfall could turn wintry in the north and west of the country, as well as on higher ground.
While the low temperatures may be closer to January averages, they come after many weeks of mild temperatures, torrential rain and flooding.
Meanwhile, the National Coordination Group urged the public to be vigilant when driving as there may be flooding on roads. Motorists are advised to slow down in affected areas and to check local authority websites for information on diversions.
