The Met Office have issued a Yellow weather warning for snow and ice, for North Wales between 8pm Monday until 3pm Tuesday.
Possible delays on roads and railways across the area, with longer journey times expected.
Temperatures across the region are set to plummet to below -6 during Monday night.
In a statement, the Met Office have said “Snow is likely to be confined to hills above 100 metres over Northern Ireland, but to low levels elsewhere.
Away from coasts, 1-3 cm of snow is possible with up to 5 cm above 200 metres. As skies clear from the west early on Tuesday morning, ice is likely to develop across western Scotland and Northern Ireland.
This warning has been updated to extend the southern boundary further south across parts of Wales for snow, and further north over Orkney to cater for the ice risk following clearance of rain or sleet here on Monday morning.
The start time has also been brought forward to 8pm.”
