Passengers flying from London airports this week have been warned of potential delays and cancellations due to a new fog warning issued by the Met Office. The alert, which came into effect at midnight on Wednesday, December 17, and lasts until around 10am, is expected to cause significant disruption across the capital's transport network.
The Met Office has warned that dense fog could reduce visibility to below 100 metres, creating difficult conditions for both air and road travel. Airports including Stansted, Heathrow, London City, Gatwick, Luton and London Southend may all experience delays, with some flights potentially cancelled.
As well as air travel, the fog is expected to affect roads and public transport, with the Met Office advising drivers to check their fog lights before setting off and to allow extra time for journeys. Bus and train services may also face disruptions.
The warning comes during one of the busiest travel periods of the year, with Heathrow Airport describing itself as “fully prepared” for its busiest December on record. Travellers are urged to check with their airlines for updates and follow advice from transport operators.
The fog is forecast to slowly clear from the west after dawn, but may linger until mid-morning in eastern parts of the warning area, which covers the southeast and parts of central England.
