MET ÉIREANN IS WARNING OF further freezing temperatures tonight, down to as low as minus-8 degrees in the east.
Further hail, sleet and snow showers are expected, particularly in east Leinster and east Munster, and more snow is likely to fall inland and on higher ground.
Freezing fog is predicted for across the country.
AA Roadwatch urges drivers not to travel unless absolutely necessary, particularly in Galway, Clare, Dublin and Wicklow.
It says that secondary roads continue to be dangerous around the country, particularly on higher ground.
It also reminds motorists who are planning to venture out to remove snow from the roof of their vehicle beforehand, in case it falls onto their windscreen while driving. Boiling water should not be used to defrost vehicles.
AA also recommends drivers double their braking distance and drive slowly. Travel updates are constantly being posted on the AA website and via their Twitter account.
