Yellow fog alert warning to drivers runs until mid-morning
Conditions could slow down public transport
A yellow fog alert has been issued by the Met Office and motorists are being warned of potentially dangerous driving conditions across South Yorkshire.
The warning runs until 10am this morning.
Forecasters say that the fog will be dense in places - with visibility below 100 metres at times - and likely to bring some travel delays.
Drivers are being urged to slow down and expect longer journey times.
A Met Office spokesperson said: “Give yourself the best chance of avoiding delays by checking road conditions if driving, leaving extra journey time, or amending plans if necessary.
“Make sure you know how to switch on your fog lights, and check they are working before setting off on your journey.
“Bus and train services, as well as flights and ferry travel may also be affected; check for updates from your travel company and follow their advice.
“Be prepared for weather warnings to change: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.”
