Fog is blanketing parts of the UK this morning, with commuters likely to face travel delays.
Workers in Portsmouth, Bath, Birmingham, Stoke-on-Trent, Nottingham and Manchester have all woken up to fog on Tuesday.
The Met Office has said that people should expect slower journey times with delays to bus and train services possible.
There is also a chance of delays or cancellations of flights.
A weather warning from the forecaster said: “Areas of fog, dense in places, have developed and will be stubborn to clear through much of this morning.
“Whilst some fog is likely to persist all day, many places will see this lifting into low cloud or clear by this afternoon.”
They added: “Mist and fog will lead to difficult driving conditions this morning, and the fog will linger all day in some places.
“Away from the fog it will be a frosty but sunnier start to the day.”
The warning is in place until 11am today but weather conditions could still affect travel later in the day.
Oli Claydon, meteorologist at the Met Office, said that there would continue to be some fog throughout the week.
“We are likely to see fog overnight tonight in similar places to where we had last night,” he said. “Again it will start to clear through the morning tomorrow. It’s a similar picture Wednesday night into Thursday as well. It could be that we see further fog warnings popping up over the rest of this week.”
He added: “For the next couple of days, there will be settled conditions compared to the last few weeks. There will be a couple of showers in the far South West and far North West, but generally speaking a much drier picture.
“It will be drier than we’d had of late.”
Speaking about the chance of snow, he added: “With the colder easterly breeze coming in, we could see some snow over the high ground in Scotland and over the Pennines. But the risk of snow is still confined to the high ground. Nothing out of the ordinary and nothing expected in the short term to lower levels.”
