Donegal County Council have warned that roads may remain slippy today following the cold snap last night in which temperatures plummeted to -3.
Similar temperatures are expected tonight, with freezing fog returning with lows of -3 and highs of +2.
Donegal County Council gritters have been out since 6 this morning on roads throughout the county.
Caution is encouraged as there may be black ice on the roads. The Council urge drivers to assume that “no road is ice-free”.
