Donegal motorists and pedestrians are being urged to take care this morning due to fog.
Gardaí have reported poor visibility in areas where there is low lying fog.
“Please drive carefully and remain alert,” a spokesperson said.
The advice from the Road Safety Authority (RSA) for driving in fog is to switch on dipped headlights and fog lamps, reduce speed and allow an extra safe distance to the vehicle in front.
Motorists should also switch off front and rear fog lamps when visibility improves.
Pedestrians and cyclists should also wear high-viz clothing and use lights.
Meanwhile, Met Éireann says the fog will lift later in the morning and it will be generally dry with hazy sunshine and just light southeast or variable breezes.
Cool with highest temperatures of 6 to 9 degrees.
Scattered outbreaks of rain and drizzle will move in across the country tonight, though parts of the east will stay dry.
Mist and fog patches too, in mostly moderate southeast winds. Lowest temperatures of 2 to 5 degrees, coldest in the northeast and east with some possible frost.
