The Met Office has a yellow warning concerning ice in place for all of Scotland and for England, with the exception of the south-west.
It warns that with falls of rain, sleet and snow dying out, there is a risk of icy surfaces and “difficult” travel conditions.
The office has told people to beware of the chance of injuries from slipping while walking on icy surfaces, as well as “some icy patches on some untreated roads, pavements and cycle paths”.
Fog is also forecast for parts of the Midlands and the North, which may pose hazards for motorists.
The yellow warning for ice is in place until 10am on today (Friday, January 15).
Heavy snowfall amid Britain’s cold snap has already caused travel disruptions across sections of northern England and Scotland.
Temperatures dipped below freezing across Lancashire this morning, dropping as low as -6C in parts of Cumbria and Yorkshire.
The Met Office has published advice from the Department for Transport advising people to clear snow and ice from footpaths outside their homes, preferably in the morning.
“You can then cover the path with salt before nightfall to stop it refreezing overnight,” the advice says.
The Met Office has also issued a weather warning for the weekend in Lancashire as a band of heavy snow is expected to blanket the county.
