Two Status Yellow weather warnings have been issued with low temperatures and snowfalls forecast in the coming days.
A Status Yellow low temperature warning has been issued for overnight tonight and early tomorrow.
Temperatures will plummet to as low as -5C overnight with a widespread sharp or severe frost as well as the risk of ice on untreated surfaces, leading to hazardous driving conditions.
Separately, a Status Yellow snow and ice warning has been issued with "treacherous road conditions" likely by Tuesday morning.
Met Éireann said up to 3cm of snow is possible in some areas tomorrow evening.
The warning comes into effect from 6pm tomorrow until 6am on Tuesday and covers Leinster, Cavan, Monaghan, Donegal, Leitrim, Roscommon, Sligo, Tipperary and Waterford.
Tomorrow will start off dry and bright but temperatures will only reach between 4-7C.
Road conditions in some parts of the country are already difficult with icy conditions reported on secondary roads around Letterkenny in Co Donegal, all routes around Loughrea, Co Galway, and around Boyle in Co Roscommon.
