A sharp Arctic blast has plunged the United Kingdom into a deep freeze at the start of 2026, with snow, ice and sub-zero temperatures disrupting road, rail and air travel across all four nations.

Weather warnings from the Met Office and health alerts from the UK Health Security Agency are in force as forecasters warn that wintry conditions could persist for several days, raising the risk of hazardous journeys, power cuts and isolation for rural communities.

Arctic air grips the UK as warnings escalate

Cold air sweeping in from Scandinavia has sent temperatures well below freezing in many areas on 1 January, with forecasters warning of a prolonged cold spell as the new year begins.

The Met Office has issued a combination of yellow and amber weather warnings for snow and ice, covering large parts of Scotland, Northern Ireland, Wales and England.

In northern Scotland, where conditions are expected to be most severe, amber warnings highlight the likelihood of heavy snow, blizzards and drifting on higher routes.

Across northern and northeastern Scotland, including parts of the Highlands, Aberdeenshire, Moray, Angus and Perth and Kinross, forecasters say 10 to 20 centimetres of snow is likely even at some lower levels, with 30 to 40 centimetres possible over higher ground.

Gusty winds are expected to lead to whiteout conditions at times, making travel extremely difficult and raising the risk that some rural communities could be cut off.

Police in Scotland have urged people to avoid non-essential journeys while the amber warnings are in place.

Further south, yellow warnings for snow and ice cover a broad swathe of England and Wales from early on 2 January, including parts of the Midlands, northwest England, London and the South East, and extending into Wales.

While accumulations here are expected to be lower, with around 2 to 5 centimetres possible in some places and higher totals over hills, the combination of wintry showers and freezing temperatures is likely to create icy surfaces and hazardous conditions on untreated roads and pavements.

In Northern Ireland, separate yellow warnings are in force for snow and ice, with wintry showers and sharp frosts forecast.

Forecasters say the pattern of frequent snow and hail showers, interspersed with bright but bitterly cold spells, is typical of an Arctic northerly airflow and may persist through at least the first week of January.

Transport networks strained by snow and ice

Transport operators across the UK have warned of delays and cancellations as the cold snap intensifies. Road conditions are deteriorating rapidly in some northern and upland areas, where snow is settling on already frozen surfaces.

National Highways has deployed gritters and snowploughs on key motorways and major A-roads, but has cautioned that even treated routes may remain difficult to navigate during periods of heavy snowfall and freezing rain.

Drivers are being advised to allow extra time for journeys, stick to main routes where possible and be prepared for sudden changes in conditions, particularly overnight and in the early morning when temperatures are at their lowest.

Traffic cameras have already shown vehicles struggling on higher sections of trunk roads in Scotland and northern England, and there have been reports of minor collisions attributed to skidding on ice and compacted snow.

On the railways, operators have warned that snow and ice on tracks and overhead lines could lead to speed restrictions and last-minute alterations to services.

Icy points, frozen equipment and reduced visibility may force trains to run more slowly on exposed sections of line, lengthening journey times on some key intercity and commuter routes.

Passengers are being urged to check timetables before travelling and to monitor operator updates throughout the day.

Airports are also braced for disruption, especially in Scotland and northern England where heavier falls are forecast. While most major airports have snow-clearing equipment and de-icing operations in place, bands of intense showers can quickly cover runways and taxiways or require repeated de-icing of aircraft, which in turn can trigger knock-on delays.

Travellers are being advised to allow extra time to get to the airport and to check the status of flights with airlines before leaving home.

Health and infrastructure under pressure in deep freeze

Alongside the travel disruption, the cold spell is placing additional strain on health and emergency services. The UK Health Security Agency has issued amber cold health alerts across much of England, signalling a high likelihood of impacts for the health and social care sector.

The alert warns that cold conditions could contribute to an increase in heart attacks, strokes and respiratory problems, particularly among people aged over 65 and those with pre-existing health conditions.

Health experts are urging the public to keep indoor temperatures to at least 18 degrees Celsius where possible, to wear several layers of clothing rather than one thick layer and to ensure that vulnerable family members, neighbours and friends have adequate heating, food and any necessary medications.

There is particular concern for people who may struggle with energy costs, as longer spells of freezing weather can significantly increase heating demand.

Local authorities and utilities are also monitoring the risk to critical infrastructure. Prolonged sub-zero temperatures can increase the likelihood of burst pipes and water mains, while heavy, wet snow and ice can bring down branches and power lines.

Councils have activated cold-weather plans, including opening additional emergency accommodation in some areas for rough sleepers and arranging welfare checks in communities likely to be hardest hit.

In rural and coastal regions of Scotland and northern England, where roads are more exposed and communities more dispersed, contingency arrangements are being readied in case villages are cut off by drifting snow or blocked routes.

Emergency services are working with volunteer mountain rescue and community groups to ensure that essential supplies and medical support can be delivered if normal access is severed.

Staying safe on the roads in severe winter weather

Road safety organisations and motoring groups are urging drivers to take a cautious approach as conditions worsen. The consistent message is that if the Met Office is highlighting a high risk of snow and ice, particularly under amber warnings, people should carefully consider whether their journey is truly necessary.

In some instances, postponing travel until conditions improve may be the safest option.

For those who must drive, preparation is critical. Motorists are advised to clear all snow and ice from windows, mirrors, lights and the roof of their vehicle before setting off, and to ensure that windscreen washer fluid, wiper blades and lights are in good working order.

Checking tyre tread depth and pressure is particularly important in cold weather, as worn or underinflated tyres significantly reduce grip on snow and ice.

Experts recommend carrying a winter kit in the car, including warm clothing and blankets, water and snacks, a torch, a fully charged mobile phone and in-car charger, an ice scraper, de-icer, and where possible a small shovel and high-visibility vest.

If you become stuck in slow-moving traffic or stranded due to an accident or road closure, these items can make a long wait in freezing conditions considerably safer and more manageable.

Once on the road, driving technique should be adapted to the conditions. Accelerating and braking gently, using low revs and pulling away in second gear can reduce the risk of wheelspin and skidding.

Maintaining a much larger gap to the vehicle in front is essential, as stopping distances on ice can be many times greater than on dry roads.

Drivers are also reminded to use dipped headlights in poor visibility and to be especially cautious on untreated side roads, bridges, exposed hill sections and shaded stretches where black ice may linger.

Advice for pedestrians, commuters and vulnerable travellers

Travel disruption in wintry conditions does not only affect drivers. Pedestrians, cyclists and public transport users are also facing challenging conditions as snow and ice take hold.

Local authorities and transport operators are prioritising the gritting of main roads, key bus routes and major pavements, but not all areas can be treated, and refreezing overnight can quickly undo earlier work.

People walking to work, school or public transport hubs are being advised to wear shoes or boots with good grip, to take shorter steps to improve balance and to use handrails on steps and ramps wherever available.

Carrying heavy bags in both hands can increase the risk of falls, so using rucksacks or distributing weight more evenly is recommended.

Older adults and those with mobility problems are being encouraged to plan routes carefully, avoid steep hills and consider delaying trips during the iciest parts of the day.

Commuters using trains and buses are advised to check services before leaving home and to allow extra time for their journeys, as operators implement reduced timetables or diversions. Platforms, station entrances and bus stops may be slippery even when main concourses have been treated.

Passengers are encouraged to keep an eye on announcements and to have alternative routes in mind if their usual line or service is disrupted.

For vulnerable travellers, including those with health conditions that may be worsened by exposure to the cold, planning is especially important.

Carrying essential medications, keeping mobile phones charged and informing friends or family of planned routes and expected arrival times can provide an extra layer of security if delays occur.

Community groups and local councils are reminding residents that help is often available for those who need support with transport to critical appointments during severe weather.

How long will the cold snap and travel disruption last?

Forecasters expect the Arctic air mass to remain in place over the UK for several days at least, suggesting that the risk of further snow and ice will persist into the first full week of January.

While the heaviest and most disruptive snow is forecast for northern Scotland and higher ground in the early stages, there is potential for further bands of wintry showers to move south across England, Wales and Northern Ireland as the pattern evolves.

Night-time temperatures are set to plunge well below freezing in many regions, leading to widespread frost and frequent ice on untreated surfaces.

In more sheltered rural locations, values could drop into the low minus double digits, especially where lying snow helps radiate heat away from the ground.

Daytime temperatures are forecast to remain close to or below freezing for much of the country, meaning any snow that falls is likely to linger, particularly away from coastal areas.

Met Office officials note that brief milder interludes are possible later in the period, especially in the south and west, but these may bring their own hazards.

If rain falls onto frozen ground, there is a risk of freezing rain which can rapidly coat roads, pavements and power lines in a layer of glare ice, making conditions extremely treacherous even without deep snow.

As a result, transport and emergency planners are preparing for a protracted period of weather-related disruption rather than a short-lived cold snap.

Members of the public are being urged to stay informed by regularly checking official forecasts and updates from transport providers, while also making practical preparations at home and at work.

Authorities emphasise that while the conditions are severe, many of the risks can be reduced through early planning, cautious travel decisions and support for those in the community who are less able to cope with the cold.

FAQ

Q1: Which parts of the UK are currently worst affected by snow and ice?
At the start of 2026 the most severe conditions are being reported in northern and northeastern Scotland, where amber warnings highlight heavy snow, blizzards and drifting on higher routes. Large parts of England, Wales and Northern Ireland are also under yellow warnings for snow and ice, meaning hazardous conditions are possible across a wide area, particularly on higher ground and untreated surfaces.

Q2: Should I cancel my travel plans during the weather warnings?
Authorities are advising people to carefully reconsider any non-essential journeys while warnings are in force, especially in areas covered by amber alerts. If your journey is not urgent, postponing it until conditions improve is the safest option. For essential travel, plan ahead, check forecasts and transport updates and ensure you are properly equipped for delays or changing conditions.

Q3: How can I make my car safer for driving in snow and ice?
Before setting off, clear all snow and ice from windows, mirrors, lights and the roof, and check that your wipers, lights and screenwash are working properly. Ensure your tyres have adequate tread and are correctly inflated. Carry a winter kit including warm clothing, blankets, water and snacks, an ice scraper, de-icer, a torch and a mobile phone charger so you can cope if you become delayed or stranded.

Q4: What is the safest way to drive on icy roads?
On snow and ice, drive slowly and smoothly, using low revs and pulling away in second gear to reduce wheelspin. Leave much more space between you and the vehicle ahead, as stopping distances can be many times greater than in dry conditions. Avoid harsh braking or sudden steering, and use dipped headlights in poor visibility. If you start to skid, ease off the accelerator and steer gently in the direction of the skid rather than slamming on the brakes.

Q5: How can pedestrians reduce the risk of slipping on ice?
Wear footwear with good grip and take smaller, slower steps to improve balance. Use handrails where available and avoid carrying heavy bags in one hand, which can affect stability. Try to stick to treated paths and well-lit routes, and be particularly cautious on shaded areas, steps and ramps where ice may persist even after gritting.

Q6: What health risks are associated with this cold snap?
Prolonged cold weather increases the risk of heart attacks, strokes and respiratory illnesses, especially among older people and those with existing health conditions. Cold homes can also worsen conditions such as asthma and arthritis. Health agencies recommend keeping indoor temperatures at or above 18 degrees Celsius, wearing layers of clothing, staying active where possible and checking on vulnerable neighbours, friends and relatives.

Q7: How can I prepare my home for freezing temperatures?
To protect your home, consider insulating exposed pipes and water tanks, knowing where your stopcock is in case you need to turn off the supply and keeping heating on low even when you are out to prevent pipes freezing. Ensure you have basic supplies such as non-perishable food, essential medications, batteries, torches and blankets in case conditions make it difficult to get out or if there are power interruptions.

Q8: What should I do if I become stranded in my vehicle?
If you are stuck in snow, stay with your vehicle unless you can safely reach shelter nearby. Keep the engine running periodically to provide heat, but ensure the exhaust is clear of snow and open a window slightly for ventilation. Use blankets and extra clothing to stay warm, conserve your phone battery and contact your breakdown provider or emergency services if necessary, giving them your location and describing your situation.

Q9: How long are the current snow and ice conditions expected to last?
Forecasts indicate that the Arctic air mass over the UK is likely to persist for several days into the first week of January, meaning continued risk of snow, ice and severe frosts. While there may be some day-to-day variations and regional differences, people in affected areas should be prepared for an extended period of wintry weather and ongoing travel disruption rather than a brief cold snap.

Q10: Where can I find reliable updates about the weather and travel?
For the latest weather information, rely on official forecasts and warnings issued by national meteorological services and broadcast by trusted news outlets. For transport, check updates from rail operators, airports, bus companies and road authorities before and during your journey. Avoid relying on unofficial social media posts that may be out of date or inaccurate, and always cross-check important information with official sources.
