Icy weather has continued to cause travel disruption across the north.
A yellow weather warning for snow and ice was issued by the Met Office for Thursday morning, and remains in place until 6am on Friday.
A band of rain, sleet and snow led to travel disruption, as temperatures remained low on Thursday.
The Met Office warned there was a “slight chance that some rural communities could become temporarily cut off” as a result of the wintery conditions.
Met Éireann also issued a Status Yellow snow and ice warning for Co Donegal, valid from 3pm to 8pm on Thursday, forecasting that sleet and snow could lead to accumulations in some areas, with the most significant amounts on higher ground.
This could lead to hazardous travelling conditions, poor visibility and ice on untreated surfaces.
Overnight, the coldest temperatures will be in the northern half of the island, with the lowest between zero and five degrees, and five to seven degrees in the south.
Meanwhile, temperatures will rise slightly for the north for Saturday, while the wintery weather will remain over much of Scotland, where a yellow warning remains in place until Saturday evening.
