Fog is expected to cause delays for motorists heading to work this morning.

The Met Office has issued a yellow weather warning for the weather condition.

Areas, where the warning is in effect include Swindon, Trowbridge and other parts of Wiltshire.

The warning will also affect other areas such as Cardiff in the west and Manchester in the north.

Slower journey times with delays to bus and train services are possible along with delays or cancellations to flights.

The yellow weather warning expires at 11am.

The Met Office in conjunction with National Highways has given the following advice for travelling in the fog:

  • Avoid travel if possible
  • Drive very slowly with dipped headlights, full-beam lights reflect off the fog causing a 'white wall' effect
  • Keep an eye on your speed, fog can give the illusion of moving in slow motion
  • Use fog lights, but remember to turn them off when the visibility improves
  • Don't hang on the tail lights of the car in front, rear lights can give a false sense of security
  • Watch out for freezing fog which is made of water droplets that freeze on contact with objects such as the pavement, road, car, etc. It can quickly form a layer of ice.
