Amber Snow Warning Grips UK as Freezing Conditions Bring Travel and Health Risks

Large parts of the United Kingdom are experiencing a sharp cold snap, with sub zero temperatures, snow showers and widespread icy conditions. The Met Office has issued a combination of yellow and amber warnings for snow and ice, highlighting a risk of hazardous travel, power interruptions and disruption to daily life. At the same time, the UK Health Security Agency has activated cold health alerts for England, warning that vulnerable groups, including older people and those with long term illnesses, could face significant health impacts if precautions are not taken.

This spell of wintry weather is affecting many regions at once, from coastal areas in the south west to northern and eastern Scotland. While the conditions are not expected to match the severity of last year’s widespread snow event, the combination of low temperatures, strong northerly winds and bands of sleet and snow is enough to cause problems on roads, railways and pavements.

Current Temperature and Weather Conditions

Overnight, temperatures have fallen well below freezing in several locations. Some of the lowest recorded values include around minus 6.1 degrees Celsius in Warcop in Cumbria, minus 5.8 degrees in Sennybridge in Wales, close to minus 4.8 degrees in Drumnadrochit in Scotland, and approximately minus 2.8 degrees in Altnahinch Filters in Northern Ireland. These figures reflect the depth of the cold air currently covering the UK.

During the day, most areas are only managing to reach between 2 and 6 degrees Celsius. With a brisk wind from the north, it feels even colder in exposed locations. Bands of sleet and snow showers are moving in from the sea, especially towards northern and western coasts, while more central and southern inland areas see a mix of dry periods, sunny spells and occasional wintry flurries.

Any places that have seen rain, sleet or melting snow are particularly prone to the formation of ice as the temperature drops again, creating hazardous conditions on untreated roads, smaller side streets and pavements.

Amber Warning for Heavy Snow in North Yorkshire

A key feature of the current situation is the amber warning issued by the Met Office for parts of North Yorkshire, including the North York Moors and sections of the Yorkshire Wolds. Under this amber warning, forecasters expect heavier and more persistent snow, especially on higher ground above roughly 100 metres.

Snowfall totals of around 15 to 25 centimetres are possible over hills, with slightly lower but still significant accumulations at lower levels. This level of snow is likely to disrupt travel, particularly on rural routes and higher passes. The Met Office has warned that:

• Roads may become very difficult or even impassable in places
• Some vehicles could become stranded if drivers venture out in poor conditions
• Power supplies and mobile phone coverage could be affected by snow and ice on lines and equipment

As a result, people in the amber warning area are advised to avoid travel unless it is absolutely essential. Local councils, including North Yorkshire Council, have sent gritting crews to treat priority routes such as main roads and key bus corridors. However, authorities emphasise that gritting does not guarantee a completely snow or ice free surface, so drivers and pedestrians should still take great care.

Yellow Warnings Across the UK

Alongside the amber warning, the Met Office has placed several regions under yellow warnings for snow and ice. These warnings cover:

• Parts of Cornwall and Devon in the south west of England
• Carmarthenshire, Ceredigion, Pembrokeshire and Swansea in south west Wales
• North East England, south west Scotland, the Lothian Borders, and Yorkshire and the Humber
• Central and northern Scotland
• Norfolk, Suffolk, Cambridgeshire and Lincolnshire in eastern England
• Northern Ireland

In these areas, forecasters expect 2 to 5 centimetres of snow even at low levels, with up to 10 to 20 centimetres likely on the highest ground in northern Scotland. The yellow warnings highlight the risk of:

• Slippery surfaces and difficult driving conditions
• Minor travel disruption and localised delays to road, rail and air journeys
• Some interruptions to rural communities and exposed locations where drifting can occur

Yellow warnings act as an early signal for the public and organisations to prepare for potentially challenging conditions, even if the impacts are not expected to be as widespread as those in an amber warning zone.

Thundersnow and Wintry Showers

Forecasters have also mentioned the possibility of thundersnow in certain areas, including the North York Moors and parts of the Scottish Highlands. Thundersnow is a rare but striking weather phenomenon that occurs when thunderstorms develop in very cold air. Instead of heavy rain, the storms produce intense snow showers accompanied by thunder and lightning.

While the thunder may be quieter than in a typical summer storm, the snowfall can be heavy, reducing visibility and leading to rapid accumulations in a short period of time. Drivers who encounter such conditions may find that road surfaces become covered quickly, even if they were previously clear.

For much of the rest of the UK, Thursday is expected to bring a frosty start followed by a mainly dry day with some bright or sunny spells. However, isolated wintry showers cannot be ruled out, and surfaces may remain icy in shaded or untreated areas.

Impact on Transport and Services

Transport networks are already feeling the effects of the cold snap. National Rail has warned that speed restrictions may need to be imposed on some routes where snow and ice are affecting tracks and overhead lines. These restrictions can lead to delays, altered timetables or cancellations of services.

On the roads, some routes in Scotland, Derbyshire and north west Wales have already experienced closures due to snow and ice. Gritting operations and snow clearing are ongoing, but motorists are encouraged to check local travel updates and weather forecasts before setting off. Those who must drive should allow extra time, slow down, and carry winter essentials such as warm clothing, a torch and a charged mobile phone.

Schools have also been affected, with dozens of closures reported in parts of Scotland on previous days as staff and pupils struggled to travel safely. Further localised closures remain possible if conditions deteriorate again.

Health Risks and Cold-Weather Alerts

In response to the severe cold, the UK Health Security Agency has issued cold health alerts for England. Amber level alerts are in place for the North West, North East and Yorkshire and the Humber, while other regions are covered by lower level yellow alerts until Saturday morning.

These alerts are mainly aimed at health and social care providers, helping them to plan for increased demand triggered by cold conditions. Very low temperatures can aggravate respiratory and cardiovascular conditions, and can be particularly dangerous for:

• Older adults, especially those living alone
• People with chronic health conditions such as heart or lung disease
• Very young children
• People who cannot afford adequate heating or who live in poorly insulated homes

The alerts encourage services to identify at risk individuals, check on them where possible, and ensure they have access to warmth, food, hot drinks and any necessary medications.

Looking Ahead: When Will It Turn Milder

Although the current cold snap is causing short term disruption, it is not expected to persist at its current intensity for an extended period. Forecasts indicate that temperatures should gradually become milder by the weekend, returning closer to the seasonal average by Saturday.

While some patches of snow and ice may linger, especially on high ground and in shaded areas, the overall risk of severe disruption should ease as slightly warmer air moves in. Even so, people are advised to stay up to date with the latest Met Office forecasts and any changes to weather warnings, as conditions can evolve quickly.

Frequently Asked Questions

1. What is the difference between a yellow and an amber weather warning?

A yellow warning signals that severe weather is possible and that people should be aware of potential disruption. An amber warning indicates a higher likelihood of impacts, such as more widespread travel disruption, a greater risk to life and property, and a stronger need to change plans or avoid travel.

2. Which areas are most at risk from heavy snow in this cold spell?

The most at risk areas are parts of North Yorkshire, including the North York Moors and some of the Yorkshire Wolds under the amber warning. Higher ground in northern Scotland is also likely to see significant snow accumulation, with up to 20 centimetres possible in some locations.

3. How should I prepare if I need to travel during the warnings?

If travel is essential, check the latest forecasts and traffic updates before leaving. Allow extra time, drive slowly, and keep a safe distance from other vehicles. Carry warm clothing, sturdy footwear, water, snacks, and a fully charged mobile phone. If your journey is not essential, consider postponing it until conditions improve.

4. Why are cold spells considered dangerous for health?

Cold weather can increase blood pressure and strain on the heart, aggravate existing respiratory or cardiovascular conditions, and make infections more likely. Vulnerable people may struggle to keep their homes warm, which can worsen these health risks. That is why agencies issue cold health alerts and advise checking on older neighbours, friends and relatives.

5. Are cold spells becoming less frequent due to climate change?

According to long term observations by the Met Office, the frequency, duration and intensity of cold spells in the UK have decreased in recent decades. External, air and ground frosts have reduced by around a quarter since the 1980s, which is consistent with the broader warming trend linked to climate change. However, individual cold snaps like the current one can still occur even in a warming climate.
