Met Office issues yellow warning for dense fog in South West England

The Met Office has issued a yellow weather warning for Swindon, Wiltshire and Gloucestershire due to an expected spell of dense fog. The warning starts at midnight on Sunday, November 8, and remains in force until 10 a.m. on Monday.

Visibility could drop to as low as 50 metres in some locations, with conditions improving only gradually by mid-morning. The agency warned that the fog may lead to slower journeys and challenging driving conditions across the region.

"Patchy, dense fog is expected to develop during Saturday night with the visibility falling to less than 50 metres in places. Fog is expected to become increasingly widespread within this area during the second half of the night before only slowly clearing during Sunday morning; slowest across parts of the West Country and central southern England," the Met Office said.

Motorists have been advised to use fog lights, check travel updates before departing and allow extra time for their trips. Residents, especially those on rural routes and major roads during the morning rush hour, are urged to be prepared for rapidly changing visibility. Train and bus passengers have also been warned of possible delays, and flight cancellations could occur.
