New snow and ice warnings have been issued across most of the country with heavy disruption expected.
Weather and travel alerts are in place across much of England and parts of Scotland after widespread snow fall in recent days.
The Met Office has warned that further heavy snowfall could cause “difficult” travel conditions as it move eastwards on Saturday.
People are being told to be aware 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”.
Warnings have been issued for the East Midlands and the North East in England, and for the Central, Tayside and Fife areas of Scotland.
The West Midlands, Yorkshire and the Humber, London and the South East are also likely to feel some effects, according to the Met Office’s warning.
Fog is also forecast for parts of the Midlands and the North, along with mist around Glasgow which may pose hazards for motorists.
Temperatures were as low as -6C early this morning in parts of Yorkshire and Cumbria, with yellow warnings set to last through most of Friday.
The Met Office has also published advice from the Department for Transport advising people to clear snow and ice from footpaths outside their homes, preferably in the morning.
It said: “You can then cover the path with salt before nightfall to stop it refreezing overnight.”
It comes after “hazardous” conditions on Thursday caused problems for the ambulance service in Yorkshire, which struggled to keep up with the high demand, while Covid vaccinations were also affected.
Mark Millins, of Yorkshire Ambulance Service NHS Trust, said the bad weather was having a “severe impact” on its operations and urged people to “take extra care” when out walking or driving.
The deepest snow on Thursday was in Bingley, West Yorkshire, and Strathallan in Perth, Scotland, both of which recorded 11cm.
Becky Mitchell, meteorologist at the Met Office, said: “Saturday is the next day we could potentially see some snow.”
The adverse weather conditions have also affected Covid vaccinations.
