A yellow weather warning is in place for parts of South East England as a blanket of thick fog is expected to sweep over parts of the UK from Monday morning.
It comes as Britain is in the middle of a cold snap, with snow hitting many areas of the country on Friday and the chilly weather expected to last until at least Tuesday.
The yellow weather warning is in place from 4am until 11am tomorrow.
It covers from the area around Norwich in the east of England down over Oxford, across parts of Dorset, Somerset and Hampshire then east along the coast over Portsmouth, Brighton and the Kent coastline.
A combination of the fog and heavier traffic as people commute to work may cause some disruption to transport.
Delays to bus and trains services is possible and there’s a chance of delays or cancellations of flights.
There are also two yellow weather warnings in place for rain over parts of Scotland from tomorrow.
Heavy rain will fall around Peebles, just below Edinburgh from 6pm tomorrow, lasting until 6am on Tuesday.
Around Inverness and Aberdeen, heavy rain will also fall from 6pm tomorrow and last until 9pm on Tuesday.
Brits across the country had snow and very cold weather to contend with last week, as the mercury plunged to -9.6C on Thursday night into Friday.
Meteorologist Bonnie Diamond said: “December has got off to a much colder start than last month, with widespread low temperatures bringing the risk of frost, ice and wintry weather across the country.
“With temperatures generally limited to between 4 to 7 Celsius by day and falling widely below freezing overnight, a cold weather alert has been issued covering much of northern England and will remain in place until at least next Tuesday.”
The coldest night of 2020 so far was minus 10.2C (13.6F), recorded at Braemar in Aberdeenshire on February 13.
The Met Office previously warned icy conditions are likely to persist at least until Tuesday.
Meteorologist Steven Keates said: “In summary, it’s a bit messy this weekend. It’s staying cold, gradually becoming a bit drier and we’ll switch our attention to some overnight frost, and I think tomorrow morning will see some dense freezing fog patches in places.”
Tonight will be cold and frosty for many across the country. Freezing fog patches are expected to develop over parts of Northern Ireland and eastern, southern and central England where some dense patches by dawn.
