Severe travel disruption possible as dense fog returns
Thick fog could bring severe disruption to commuters for a second day this week across parts of England and eastern Wales.
A Met Office warning is in place for the fourth consecutive day, this time covering the Midlands, East Anglia, the northern home counties, Yorkshire and the Humber and parts of Cheshire.
North-eastern counties of Wales such as Powys, Denbighshire, Conwy, Flintshire and Wrexham are also included in the warning.
The warning began at 18:00 GMT on Monday and runs until 10:00 GMT on Tuesday.
The Met Office yellow warning for fog across parts of the UK lasts into Tuesday morning
Forty flights were cancelled at Heathrow Airport on Monday before fog cleared.
On Saturday night, thick fog blanketed parts of England and Wales, making an FA cup match between Altrincham and Notts County less of a spectator sport.
It also caused a 30-car pile-up on the M20 in Kent on Saturday leaving two people seriously injured, as well as a 19-car collision on the A303 in Hampshire.
On Tuesday, visibility could be reduced to less than 100m in places which could lead to further travel disruption.
Patchy fog could also develop outside the warning area where the skies clear.
