Severe weather warnings are in place across Britain for 24 January, with ice, sleet and snow forecast.
The Met Office has also issued a yellow warning, its second highest alert.
Freezing temperatures are expected in some areas, which will cause dangerous ice patches on roads and pavements.
The warning includes an area that spans from the Scottish Highlands to the English Midlands.
"Rain will move east across the UK during Tuesday morning and is likely to turn to sleet and snow for a time across northern and eastern areas, giving some moderate accumulations of snow above 200-300 metres," a statement from the Met Office said.
"Icy patches are also likely where rain falls on to sub-zero surfaces. The public should be aware of the risk of disruption to travel, chiefly to routes over higher ground."
