The Met Office has issued yellow weather warnings for fog across large parts of the UK, with drivers told that thick fog could make travelling difficult on Monday, November 9.
The warnings cover areas including London, the Midlands, Yorkshire, Wales and Northern Ireland. Forecasters say visibility could fall to just 50 metres or less in some places, with disruption possible for people heading to work or school this morning.
Warning times and coverage
The main warning, covering much of England and parts of Wales, came into force at 6pm on Sunday and will remain in place until 11am today. A separate warning for Northern Ireland began at 10pm on Sunday and is due to expire at 10am.
The Met Office said: "Fog leading to difficult travel conditions and possible delays." It warned that journeys could take longer than usual, with delays to bus and train services possible. Flights could also be delayed or cancelled if conditions become particularly poor.
Areas affected
Areas covered by the main warning include Greater London, Kent, Essex, Surrey, Hampshire, Hertfordshire, Norfolk, Suffolk, Derbyshire, Nottinghamshire and Lincolnshire. Parts of Greater Manchester, Merseyside, Cheshire, Yorkshire and the West Midlands are also included.
In Wales, the warning covers areas including Cardiff, Newport, Powys and Wrexham. All six counties of Northern Ireland are covered by the separate alert.
Advice for travellers
The Met Office said fog developed overnight and could become particularly dense in some areas before gradually clearing during Monday morning. Drivers are being advised to check road conditions before setting off and allow more time for their journeys. Motorists should also make sure their fog lights are working and know when to use them.
Anyone travelling by train, bus or plane should check with their transport provider for updates before leaving home. The Met Office has warned that weather alerts can change, so people are being encouraged to keep checking the latest forecast.
Although the warnings are expected to expire later this morning, fog may take longer to clear in some places. People travelling through affected areas should be prepared for slower journeys until visibility improves.
