Publicly available information from the Met Office shows a yellow fog warning in place from 6 p.m. on Sunday 8 November until 11 a.m. on Monday 9 November, covering London and South East England along with large parts of the Midlands and other English regions. The alert highlights the risk of dense fog patches and very poor visibility developing during the evening and persisting overnight.
The warning notes that fog is expected to form quickly after sunset, becoming widespread and in places very dense, before slowly lifting through the late morning period on Monday. London sits within one of the core zones of concern, with visibility on some routes potentially dropping below 100 metres at times.
Recent national coverage describes current conditions as a “perfect recipe” for fog, with light winds, clear skies and moist air combining to trap low cloud near the surface. Earlier patches across Wimbledon Common and other parts of southwest London on Sunday morning offered a preview of the thicker conditions expected to return after dark.
While a yellow warning is the lowest of the Met Office’s three impact levels, it signals that travellers should expect slower journey times, localised disruption and the possibility of sudden changes in visibility from one district to the next.
Met Office guidance on the fog warning emphasises that road journeys across London and the surrounding commuter belt are likely to be affected, particularly on Sunday evening and through the early hours of Monday. Visibility may fall below 200 metres on sections of the M25, A40, A2 and other key approaches into the capital, with denser pockets potentially cutting that distance far further.
National Highways information for previous fog events highlights the likelihood of variable conditions, where clear stretches of motorway are followed abruptly by thick fog banks. For drivers, that pattern can be especially challenging, as it encourages higher speeds just before visibility deteriorates sharply.
Travel reports during similar recent fog episodes in England have pointed to slower traffic flows, minor collisions and congestion around junctions as motorists adjust to poor visibility. Overhead motorway signs and urban variable message displays around London are expected to carry fog and speed advisory messages once conditions deteriorate.
Drivers planning longer journeys on Sunday night are being encouraged, through public forecasts and travel bulletins, to allow extra time, reduce speed where necessary and ensure that headlights and, where appropriate, fog lights are used correctly. Those using car-sharing, ride-hailing services or late-night taxis may also find journey times extended on popular routes in and out of central London.
According to recent coverage of similar fog warnings, rail networks in England typically remain operational but can experience slower speeds and minor delays when visibility drops. Signals and trackside equipment are designed to function in low-visibility conditions, but precautionary speed restrictions are sometimes introduced on open sections of line.
For London, this can have knock-on effects on mainline services operated out of hubs such as London Waterloo, London Victoria, London Bridge, Euston and…
