A WEATHER warning of freezing fog and ice has been issued, lasting until 11am tomorrow morning.

The yellow 'be aware' warning for the south west, including Swindon and Wiltshire council areas, says areas of freezing fog, some dense, is valid from 6pm today until 11am on Wednesday.

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

"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."

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

On Monday morning Dorset Police reported 31 collisions in icy conditions, six times more than would occur at that time on an average weekday.

  • Other areas affected by the latest warning include Bristol, Bath and North East Somerset, Dorset, Gloucestershire, Somerset, South Gloucestershire, Devon and North Somerset.
