Met Office Yellow Fog Warning Disrupts Travel Across the UK
Understanding the Met Office Yellow Fog Warning
The Met Office has recently issued multiple yellow fog warnings across various regions of the United Kingdom, signalling potential disruptions to daily life and travel. Freezing fog is expected to develop across parts of southeast England with visibility potentially falling below 100 metres in places. These warnings, whilst the lowest severity level in the three-tier system, serve as crucial alerts for residents to take precautions during hazardous weather conditions.
Recent Fog Warning Incidents
Throughout late November and early December 2025, the UK has experienced a series of yellow fog warnings affecting different regions. The Met Office issued a yellow fog weather warning for Coventry and Warwickshire on December 3, warning that driving could be difficult, with fog patches dense in places and mainly in rural areas. A yellow weather warning for fog has been issued for the southeast, coming into effect from midnight on December 4 until 9am on Friday (December 5), with areas of freezing fog potentially leading to travel delays on roads and delays or cancellations to flights.
Impact on Travel and Daily Life
The fog warnings have caused significant disruptions across multiple transport sectors. Airports which may see delays and cancellations to flights include Manchester, Birmingham, Leeds-Bradford, Humberside and East Midlands. Road users face particularly challenging conditions, with visibility less than 100 metres in places, making driving hazardous especially during morning rush hours.
Public transport services have also been affected. Bus and train services, as well as flights and ferry travel may be affected, with passengers advised to check for updates from travel companies and follow their advice.
Safety Advice and Precautions
Yellow warnings indicate potential impacts and advise people to check the forecast and take precautions. The national meteorological service has urged Britons to stay safe by checking road conditions, allowing extra travel time, or adjusting plans if necessary. Motorists are specifically advised to ensure fog lights are functioning properly before setting off and to maintain greater following distances.
Weather Context and Future Outlook
Fog is more common in the colder months as long, clear nights allow the ground to cool rapidly. There is a greater chance of spells of high pressure during this period, bringing more dry weather, which will increase the chances of overnight fog and frost. Residents should remain vigilant and check weather forecasts regularly, as conditions can change and warnings may be updated at short notice.
