Snow and ice is forecast throughout the weekend.
Every county on the island of Ireland will be under a weather warning for a time this weekend, as a period of low temperature and snow sets in.
The UK Met Office has a yellow warning for snow and ice in place for all of Northern Ireland between 3pm on Friday and midday on Saturday.
That will immediately be followed by another yellow warning until midday on Monday in more northern areas.
Forecasters said cold northerly winds will bring sleet and snow showers across much of Northern Ireland on Friday afternoon, overnight and into Saturday morning, bringing the likelihood of ice on untreated surfaces.

There could potentially be 2-5cm of snow accumulating on higher routes on Friday, forecasters said.
The Met Office said: “Snow showers will continue to affect many parts of Northern Ireland over the weekend, before gradually easing on Monday.
“The heaviest and most frequent snow showers will be in the north, although along the north coast these may fall as rain or sleet at times.
“Whilst not all locations in the warning areas will see snow, around 1-3cm is expected to have fallen in many places by Monday morning, with the potential for 5-10cm to build up in a few locations, especially over higher routes, such as Glenshane Pass.”
In the Republic of Ireland, Met Eireann has issued a yellow warning for snow and ice for Donegal between 8pm on Friday and 11am on Saturday.
