A Met Office fog warning was in force from 4am for parts of North Wales this morning, and the forecast said it could run until 10am before easing later. For travellers asking what is fog in practical terms, this warning pointed to reduced visibility and slower journeys on roads and public transport.
North Wales Fog Warning
The warning covered parts of east Wales running down from Flintshire to Wrexham and small areas of Denbighshire, while also stretching across large areas of the Midlands and the north of England. That wider spread matters for readers moving through the region, because the same fog system was affecting several travel corridors at once.
The Met Office said fog was likely to lead to some transport delays this morning. It also warned that some areas could see dense fog with visibility below 100 metres at times, which is the point where travel decisions become much more cautious for anyone driving, waiting for a bus, or connecting to another service.
Met Office Travel Advice
The forecaster said the fog would slowly begin to thin, lift and clear later this morning or, in some spots, not until this afternoon. That creates a split timetable for travellers: some places may improve around the end of the warning, while others could still be dealing with poor visibility well after 10am.
The Met Office advised people to check road conditions if driving, leave extra journey time or amend plans if necessary, and make sure they knew how to switch on their fog lights and checked they were working before setting off. It also said bus and train services, as well as flights and ferry travel, may be affected, with updates from travel companies the main source of live changes.
Delays Beyond 10am
The warning was due to end at 10am, but fog could still linger into the afternoon in some areas. Which specific services or routes will be delayed or cancelled is not answered in the warning itself, so anyone travelling through North Wales and the wider affected regions has to rely on live updates rather than the clock alone.
