THE Met Office has issued a yellow warning of fog across the South West.
Freezing fog patches will become more widespread and dense during Wednesday evening, overnight and through Thursday morning.
Driving conditions will be difficult with journeys likely to take longer than usual.
The Met Office has also warned their could be some disruption to flights.
It is expected that in some parts of the South West, temperatures tonight will fall to below freezing, so there is also the risk of ice forming on some untreated surfaces particularly later in the night and early on Thursday morning.
The fog patches are expected to slowly thin during Thursday, although some patches may persist throughout the day - most likely in a zone from the West Country to Eastern England.
