Millions face travel chaos and treacherous conditions as the Met Office issues yellow weather warnings for snow and ice across Northern Ireland, much of Scotland, northern England, and parts of Wales over the coming days.
Snow showers will hit higher ground in Scotland and northern England, whilst lower areas face sleet or light dustings. The main threat comes from widespread ice forming on untreated roads, pavements and surfaces as overnight temperatures plummet significantly.
Scotland bears the brunt of the warnings, covering the Highlands, Grampian, and Strathclyde where substantial snow accumulations are expected. Northern Ireland will see wintry showers creating icy patches, particularly treacherous during morning commutes. Northern England, including Cumbria, Northumberland, and the Pennines, faces similar hazardous conditions.
Northern and central Wales will also feel the cold snap's bite, with overnight ice development likely to catch out early morning travellers. Whilst central and southern England escape snow warnings, temperatures remain bitter with localised icy patches possible on rural roads and higher ground.
Drivers must check routes beforehand, allow extra journey time and reduce speeds, the Met Office warns. Pedestrians should wear proper footwear and watch for slippery surfaces. Councils are deploying gritting lorries for major routes, but side roads and pavements remain dangerous.
Daytime temperatures will struggle between 0°C and 4°C across affected regions, whilst overnight lows could hit -3°C or lower in sheltered spots. Moderate winds of 10-15mph will make conditions feel even colder, especially in exposed areas.
