Freezing fog and wintry showers are forecast for the coming days, as Ireland enters a cold snap.
Met Éireann has issued a status yellow low temperature and ice warning for the entire country tonight.
While people in Donegal, Dublin and Wicklow can expect sleet and snow showers.
Minister of State for local government Peter Burke says councils have grit at the ready.
''We have very strong levels of stocks of salt which is very important to keep our roads gritted and also we are obviously concerned by freezing fog potential wintry showers and snow showers. So obviously motorists have to be very careful over the coming days and it's very important that all citizens keep a very close check on Met Eireann and winter ready.''
It seems the cold snap may put more pressure on Ireland's electricity system in the coming days.
Muireann Lynch from the ESRI says we seem to have enough supply to meet demand - but energy reserves are low.
