Freezing and dense fog is set to form for the third day running, the Met Office has warned.

A yellow warning has been issued for Bournemouth, Poole and Dorset and is valid from 6pm on Tuesday until 11am on Wednesday.

Icy patches could also form on untreated surfaces and paths. 

The warning says: "Areas of freezing fog, some dense, are expected to form again during Tuesday evening and last into Wednesday morning.

"The fog will become more widespread through the night, with icy patches on untreated roads and paths an additional hazard.

"Travelling conditions will be difficult with journeys likely to take longer than usual and delays to air travel are possible."

The Chief Forecaster said: "Stagnant air will remain across the area, allowing fog to form readily.

"Frost deposited by the fog will give surfaces an icy covering which may be thick enough to make roads and pavements slippery."
