Grim weekend ahead as experts warn frost, ice and freezing fog 'will be an issue'

Met Éireann has delivered a grim forecast for Ireland for the days ahead as frost, ice, and freezing fog are expected as temperatures are set to plunge yet again.

While many areas will be dry and calm this weekend, there will be some well scattered showers with lingering fog, owing to a slack area of low pressure. Heavier and more organised bands of showers will feed in from the Atlantic later Sunday and into Monday.

No weather warnings have been issued as of yet but freezing temperatures are on the way for parts of the country giving way to black ice on roads so motorists are urged to be advised.
