Amber snow alerts have been issued across the UK as an Arctic blast brings freezing temperatures and widespread disruption to millions starting their working week.
The cold snap, which took hold over the weekend, has seen an Arctic air mass push southwards, sending temperatures plummeting well below zero overnight. Many areas will struggle to reach freezing point during the day, with widespread frost and ice forecast.
The amber warnings — a step up from yellow alerts — highlight the risk of significant snowfall, particularly over higher ground but also at lower levels in affected regions. Commuters face challenging conditions with difficult driving, public transport delays, and some rural communities potentially cut off temporarily.
The Met Office has urged the public to allow extra journey time, exercise caution, and check on vulnerable neighbours. Gritting teams are working across the country to treat roads, though icy patches remain likely on untreated surfaces and pavements.
The Arctic conditions mark a sharp contrast to recent milder weather and highlight the unpredictable nature of British winters. Beyond travel disruption, the cold snap is increasing demand on energy networks and raising health concerns for those exposed to extreme temperatures.
Meteorologists predict the freezing conditions will persist for several days, with temperatures remaining below zero and further snowfall likely throughout much of the week. The public is advised to monitor official weather forecasts and warnings regularly.
