Fog Warning Extended As Thick Mist Disrupts UK Travel

Thick fog is continuing to disrupt travel across parts of the United Kingdom, as a yellow weather warning is extended into Tuesday morning and transport operators warn of slower journeys, delays and potential cancellations.

Warning Area Widens As Visibility Drops Below 100 Metres

Publicly available information from the Met Office shows that a yellow fog warning now covers a broad swathe of England and eastern Wales from the evening of Monday 9 November until late Tuesday morning. The alert is in force from 6 p.m. on Monday to 10 a.m. on Tuesday, with forecasters highlighting a high likelihood of some travel disruption where fog becomes dense.

The latest guidance indicates that visibility in affected areas may fall below 100 metres at times, creating hazardous driving conditions and increasing the risk of disruption across road, rail and air networks. The warning zone stretches from parts of Wales across the Midlands into eastern England, taking in major population centres including London, Birmingham and Manchester, as well as key motorway corridors.

This new advisory follows a separate yellow warning that was already in place for Monday morning, which reports indicate has now been followed by a second period of thick, persistent fog redeveloping overnight. Weather briefings describe the current pattern of light winds, clear skies and long November nights as a “recipe” for widespread mist and fog formation over successive days.

According to published summaries of the UK’s National Severe Weather Warning Service, a yellow alert signals that weather conditions could cause some disruption to travel and daily life, and that the public should be aware of the potential for delays, difficult driving conditions and changes to normal transport operations.

Road Journeys Slowed After Multi-Vehicle Crashes In Thick Fog

Reports from national media outlets describe a difficult start to the working week for many motorists, particularly across the southern half of England and parts of Wales. Drivers have faced stretches of motorway and A-road carriageways shrouded in dense fog, forcing slower speeds and longer journey times during the Monday morning peak.

Coverage from UK news outlets highlights a serious incident on the M20 in Kent over the weekend, where more than 30 vehicles were involved in a collision in thick fog, leaving at least two people with serious injuries and closing a section of the road. The crash occurred ahead of the latest warning period but has sharpened focus on the risks posed by sudden visibility drops during persistent mist.

Traffic cameras and photographs published from routes such as the M11 in Essex and the M40 in the Midlands on Monday show vehicles moving with headlights and fog lights on through banks of low cloud. Transport bulletins indicate that electronic matrix signs on several major motorways have been advising drivers of fog and urging extra caution.

Local authorities and motoring organisations are directing drivers to existing safety guidance for foggy conditions, including leaving greater stopping distances, using appropriate lights rather than full beam, and allowing more time for essential journeys. Some councils have also reminded residents that non-essential travel can often be deferred until conditions improve later in the day, once the fog begins to lift.

Flight Delays At Major Airports As Low Cloud Lingers

Air passengers have also experienced disruption as dense fog has affected airports in southern and central England. According to published coverage, London Heathrow has seen a series of delays to arrivals and departures, with some short-haul services held on the ground or placed in extended holding patterns while visibility on runways and taxiways remains marginal.

Travel reports on Monday morning indicated that the combination of low cloud and thick surface fog has at times reduced visibility at Heathrow to levels that require increased separation between aircraft movements. This reduces the overall capacity of the airport and can lead to knock-on delays throughout the day, particularly on busy European and domestic routes.

Regional airports within the warning area are also reported to be affected, with passengers advised to check the latest information from airlines and airport operators before travelling. Aviation industry guidance confirms that while modern navigation aids allow planes to land in low visibility, airports must still meet strict safety criteria before movements can continue as normal, and dense fog can trigger temporary suspensions or diversions.

Public-facing travel advice stresses that anyone flying on Monday night or Tuesday morning should monitor airline apps or text alerts and allow additional time for transfers to and from airports, as road conditions around terminals may also be slower than usual.

Rail Services Running, But Passengers Urged To Allow Extra Time

On the rail network, there have been fewer direct cancellations attributed solely to fog, but journey planners show some slower running on certain routes as drivers proceed with additional caution where visibility is particularly poor. Historical rail safety information for the UK notes that thick fog has long been recognised as a challenge for signalling and train operations, and various technical measures are in place to help keep services moving safely when sighting distances are reduced.

National rail information platforms on Monday have been advising passengers to check their journeys before travel, especially early in the morning and late in the evening when fog is at its most widespread. While most mainline routes remain open, public information suggests that minor delays and altered stopping patterns are possible if conditions deteriorate further in coming hours.

Given the overlap between the fog warning area and some of the country’s busiest commuter corridors, even small timetable changes or speed restrictions can lead to crowding and extended journey times. Passengers connecting with other modes, such as domestic flights or ferries, are being encouraged to build in longer transfer windows than usual in case of knock-on disruption.

For overnight services and early-morning departures on Tuesday, train operators are expected to continue issuing updates as the fog evolves. Travellers planning time-sensitive connections, including international onward travel, may wish to monitor rail updates more closely or consider earlier services where possible.

What Travelers Should Expect In The Coming Day

Forecasts indicate that the thickest fog is likely to persist overnight into Tuesday, gradually thinning and lifting by late morning in many locations as temperatures rise and winds increase slightly. However, publicly available outlooks also suggest that patches of mist and low cloud could linger in sheltered areas, keeping conditions dull and damp even after the main warning period expires.

Travelers across the warning area should therefore be prepared for another slow start on Tuesday, particularly on untreated minor roads, in river valleys and across low-lying fields where fog tends to pool. Commuters using a mix of driving, rail and air are being advised through public channels to keep plans flexible, allow extra journey time and stay informed through operator updates.

For those yet to set out, journey planners recommend considering alternatives such as later departures, remote working or virtual meetings where feasible, in order to reduce pressure on the transport network during the worst of the conditions. Parking, rental car pick-ups and drop-offs, and airport transfers may all take longer than usual while visibility remains poor.

With the Met Office continuing to monitor developments and extend or adjust warnings as needed, the overall message from publicly available travel and weather information remains consistent: fog is likely to cause at least some disruption into Tuesday morning, and building in additional time and caution is the most practical response for anyone travelling across the affected parts of the UK.
