Commuters have been advised to also expect potential delays.

Posting the warning online, the Met Office said: ‘Areas of fog are likely to cause some travel delays on Tuesday morning. [Expect] delays or cancellations to flights, with slower journey times with delays to bus and train services possible.

‘Travelling in fog can be extremely dangerous. Fog can drift rapidly and is often patchy.

‘Drive very slowly with dipped headlights – watch out for freezing fog which is made of water droplets that freeze on contact with objects such as the pavement or road.’
