A weather warning for freezing temperatures with dangerous ice and fog will be in place for Galway tonight.
Met Eireann has issued a status yellow Low Temperature/Ice warning for Leinster, Cavan, Monaghan, Munster, Galway, and Roscommon.
“Very cold overnight and early Monday morning with the danger of icy patches. Some freezing fog patches locally also.”
The weather warning comes into effect at 7pm on Sunday and will remain in place until 11am Monday morning.
Motorists are advised to exercise caution due to expected difficult driving conditions, and pet owners should also be aware of animal welfare issues.
A separate low temperature warning has been issued for counties Donegal, Leitrim, Mayo, and Sligo.
More alerts are expected throughout the week as arctic air brings winter hazards until Friday at least.
Sharp to severe frosts are expected with icy stretches on roads and pavements.
Some sleet or snow will occur at times too, mostly for northern areas, and especially for hills.
