The Met Office has issued another yellow weather warning on Sunday afternoon for “freezing fog” which will “reduced visibility to 50-100 metres at times.”

They are warning drivers on Sunday and Monday morning to drive carefully as there could well be “patchy ice on untreated surfaces.”

The weather warning applies to west Scotland, Northern Ireland, the Midlands, Wales, the Cotswolds, London, the south west and south east from 4pm on Sunday until 11am on Monday morning.

Commuters should expect on “some untreated roads, pavements and cycle paths” icy patches, and there will be slower journey times with possible “delays to bus and train services.”

The Met Office has also warned “there is a chance of flight delays” or even the “cancellations to flights” amid freezing fog.

The Met Office said, “Freezing fog is expected to become more extensive overnight and could produce significantly reduced visibility to 50-100 metres at times, as well as patchy ice on untreated surfaces.

“Additionally, snowfall that is now easing near and over the Cotswolds, as well as isolated showers elsewhere may lead to some ice developing on untreated surfaces.

“Although becoming less widespread and thick by lunchtime, some places may be affected by fog for the remainder of the day, particularly in Northern Ireland and northern England.”

Met Office meteorologist Rachel Ayers said, “It will continue to be a very cold day, with maximum temperatures of 1C to 4C on Sunday, and, as we head into the evening, we see persistent rain, sleet or snow in the far South East of England, which is what we have a yellow warning out for from 6pm on Sunday.

“We could see 2cm to 5cm (of snow), perhaps up to 10cm in some places, with Kent and Sussex most affected, with areas most exposed such as North and South Downs and higher ground going to see the more significant accumulations.

“There will be ice forming, particularly near to the coast where there is rain and sleet, and freezing temperatures which could cause some travel disruption to start Monday with that valid until 9am.”

Sean Sidley, AA patrol of the year, said, “On a frosty morning, hazards like black ice can prove lethal if you don’t adjust your speed and driving style in colder weather.

“Always leave plenty of space behind other vehicles as stopping distances can be 10 times longer on icy roads.

“Allow extra time, as there may be delays to your normal routes, and make sure you pack winter essentials in the car such as warm, waterproof layers, a shovel, a torch, fully charged mobile phone and a flask of hot drink.

“Take heed of warning lights in your vehicle and make sure you check it regularly if you drive less in the winter. Flat batteries are one of the top breakdowns we attend in cold weather and can be avoided by regular car maintenance.”
