Commuters are being warned of potentially difficult driving conditions this morning due to a cold snap which has left a sharp frost with icy patches on roads and areas of freezing fog.
A status yellow temperature warning is in place for all areas this morning except for the eastern and south counties of Dublin, Wicklow, Wexford and Waterford.
Met Éireann said overnight temperatures fell to minus 4 degrees in places leading to a widespread severe frost with pockets of freezing fog.
