The Met Office has issued a yellow warning for freezing fog affecting Berkshire and Buckinghamshire.
The warning is in place from 2am to 11am on Sunday, January 22.
Freezing fog will lead to difficult driving conditions and could cause travel delays in some areas on Saturday night and Sunday morning, said the Met Office.
It means travel delays are likely and there is a chance of delays or cancellations to flights.
Untreated surfaces may become slippery, leading to increased chance of accidents or injuries.

But Met Office meteorologist Craig Snell said the worst of the cold spell is over, with temperatures expected to climb next week across the whole of the UK.
Mr Snell said: “Next week, looking at the severe front, it’s looking pretty benign.
We’re starting to lose the risk of fog and temperatures are generally around where they should be.
“We’ll probably lose the really hard frosts. In terms of ice and snow, it certainly looks like we’re over the worst.
“We’ve got to keep an eye on risk of fog generally this cold spell, although the main hazards from it look like they are beginning to diminish.”
