Met Eireann has issued two ice warnings for all counties on this “bitterly cold” Thursday.
Freezing, light snowfall and hazardous conditions have been reported across the county this morning, and another icy night is in store.
Motorists and pedestrians are also being warned to watch out for black ice.
A status yellow ice warning is in place until midday today (Thursday) and another nationwide warning will come into force again from 10pm until 12noon tomorrow.
Tonight’s alert warns of hazardous conditions due to a sharp to severe frost with icy surfaces, as temperatures widely fall to – 4 degrees Celsius. Some freezing fog patches also.
The northwest could see lows of -5 to -2 degrees and it will be “bitterly cold”.
Met Eireann says: “Friday will begin very cold with icy stretches and freezing fog in parts. Most areas will be dry with low winter sunshine. However, wintry showers will affect some Atlantic coastal counties, possibly heavy or thundery near the coast. Highest temperatures generally ranging from 1 to +4 degrees in light northwest or variable winds.”
