Yorkshire yellow fog warning prompts travel disruption alert

Dense fog is forecast to blanket parts of Yorkshire from Sunday evening into Monday morning, with a Met Office yellow warning in force and motorists, rail users and airline passengers advised to prepare for slower journeys and possible delays.

Warning area, severity and timing

The latest National Severe Weather Warning Service update shows a yellow fog warning covering Yorkshire and Humber alongside several other English regions. The alert highlights a combination of widespread mist and locally dense fog, with visibility in some pockets expected to fall to around 50 metres or less overnight.

According to publicly available Met Office information, the Yorkshire warning is valid from 18:00 on Sunday 8 November until 11:00 on Monday 9 November 2026. A separate yellow warning that started at 00:00 on Sunday and ran to 10:00 focused on earlier morning fog, indicating that conditions are likely to redevelop rather than clear completely between these periods.

Regional coverage extends across much of Yorkshire and Humber, including urban corridors around Sheffield, Wakefield, Doncaster and York. Summary feeds that aggregate Met Office alerts list Yorkshire and Humber alongside the East Midlands, West Midlands, north west and south west England, parts of the East of England, London and Wales within the broader fog risk zone for this spell of weather.

The yellow category indicates a high likelihood of low to moderate impacts rather than the widespread disruption associated with amber or red alerts. Even so, recent guidance on yellow warnings stresses that impacts can still be significant where visibility falls sharply, particularly on fast routes and near busy junctions.

Key road routes at risk of poor visibility

Transport planners and motoring organisations typically highlight the main motorway and A road network across Yorkshire as particularly sensitive to rapid visibility changes. The M62, which crosses the Pennines between Lancashire and West Yorkshire and continues eastwards past Leeds and towards the Humber, includes some of the highest motorway stretches in England along exposed moorland, where fog can form quickly and persist.

To the south, the M1 runs between London and Yorkshire, serving Sheffield, Barnsley, Wakefield and Leeds, and linking with the M62 near junction 42. Junctions with the A1 and M18 create dense clusters of traffic, where sudden reductions in visibility can increase the risk of shunts and long tailbacks when drivers are forced to slow abruptly.

Farther east, the A1 and A1(M) form the main north south spine through West and North Yorkshire, connecting Leeds, Wetherby and areas towards Catterick and the North East. Major A roads such as the A64 between York and the coast and the A19 corridor are also prone to patches of thick fog, particularly in low lying sections near rivers and open farmland.

Public guidance produced for fog events encourages drivers using these strategic routes to check live traffic and weather information before setting out, avoid last minute lane changes, and be prepared for uneven driving conditions where some stretches are clear while others drop into dense fog banks with little warning.

Impact on rail, bus and air travel

The current warning text notes that slower journey times are likely, with delays to bus and train services described as possible. On the rail network, fog can lead to more cautious driving by train operators, particularly where speed restrictions are already in place for engineering or leaf fall, which can lengthen journey times across key trans Pennine and east coast routes serving Yorkshire stations.

Regional bus services may experience localised disruption where dense fog combines with congestion or road incidents on motorway approaches into city centres. Reduced visibility around junctions and interchanges can require slower speeds, making timetables harder to maintain during the busiest commuter periods on Monday morning.

The yellow warning also refers to the chance of delays or cancellations to flights. Airports serving the wider region, including Leeds Bradford and Doncaster Sheffield’s replacement charter operations via nearby hubs, can be affected when visibility at the runway drops below the thresholds required for safe landings and take offs. In such conditions, airlines sometimes divert inbound flights, hold aircraft in stacks, or delay departures until visibility improves.

Publicly available travel advice from operators typically urges passengers to confirm the status of services on the morning of travel, allow additional time to move through terminals or interchanges, and be alert to short notice platform or gate changes when services are rescheduled because of the weather.

Safety guidance for driving in dense fog

National road safety campaigns and Met Office advice emphasise preparation before starting any essential journey in foggy conditions. Motorists are encouraged to check that dipped headlights and rear fog lights are working correctly, ensure windscreens and mirrors are clean and clear, and keep washer fluid topped up to cope with spray and grime.

Once on the move, guidance commonly highlights the need to reduce speed well below posted limits when visibility is significantly reduced, maintain larger gaps to vehicles ahead, and avoid relying solely on the rear lights of the car in front as a marker. Using full beam is discouraged in fog, as the light can reflect back and further reduce what drivers can see.

Advice also warns against sudden braking where possible, recommending instead that drivers ease off the accelerator early when approaching junctions, roundabouts and queues. On high speed routes such as the M1, M62 and A1(M), remaining in a single lane where safe and avoiding unnecessary overtaking can lower the risk of collisions when conditions change from clear to foggy within short distances.

For those who do not need to travel, public information produced for similar events often suggests postponing non essential journeys during the worst of the fog, particularly overnight and around dawn, when visibility is likely to be at its lowest and road surfaces can also be damp and cold.

Outlook for conditions after the warning period

Short range forecasts indicate that fog will form readily again through Sunday evening and night, becoming extensive across parts of Yorkshire by the early hours of Monday morning. Model guidance referenced in publicly available discussions suggests that clearance on Monday is likely to be slow, with some areas remaining grey and misty into late morning before visibility improves.

Beyond late Monday morning, when the yellow warning currently expires, forecast charts indicate a gradual transition to milder, more unsettled conditions for many areas of England, with cloud and light rain helping to disperse lingering fog patches. However, confidence around the exact timing of this breakdown remains limited, and subtle shifts in wind direction or cloud cover could extend foggy conditions in some river valleys and low lying locations.

Travel planners note that this type of radiation fog event often leads to a pattern of repeated overnight fog formation and partial daytime clearance over several days if high pressure remains nearby. As a result, travellers in Yorkshire and surrounding regions are being encouraged by publicly available guidance to monitor updated Met Office warnings and local forecasts through the early part of the week in case further alerts are issued.

Given the changing nature of fog and the potential for rapid local variations in visibility, those with time critical trips such as early morning flights, rail connections or long road journeys on Monday are advised in public information sources to build additional flexibility into their plans and check for updates before setting out.
