Two separate weather warnings for snow and low temperatures have been issued for the entire country.
From 8 o'clock tonight a low temperature/ice warning will come in to effect for all 26 counties, with temperatures set to dip to lows of minus four.
A status yellow snow and ice alert will also kick in at 11pm and Met Eireann says this could lead to treacherous conditions.
