Met Office Fog Warning Covers England, Wales and NI

The Met Office has issued a yellow weather warning for fog across large parts of England and Wales, running from 6pm on Sunday until 11am on Monday, with the potential for disruption to flights and road travel.
The warning area stretches from York to Bath and covers most of the South East and eastern England, where the fog is expected to be densest, although low cloud and patchy fog are forecast across much of the rest of the UK.
Met Office operational meteorologist Niamh Murray said there would still be patchy fog elsewhere, “just not quite as dense or as impactful”, and warned that fog could be particularly stubborn overnight into Monday in rural parts of the Midlands, Wales and East Anglia, where temperatures are expected to drop near freezing and air frost is possible.
A separate yellow fog warning covers parts of Northern Ireland, including Antrim, Armagh, Down, Fermanagh, Londonderry and Tyrone, from 10pm on Sunday until 10am on Monday, with visibility forecast to drop below 100 metres in places.
Across the border, Met Éireann has issued a status yellow fog warning from 9pm on Sunday until 11am on Monday for Connacht and seven other counties, including Donegal, Monaghan, Louth and Meath, raising the prospect of slow journeys for travellers heading to Dublin Airport.
The Met Office said fog was expected to lift gradually during Monday morning, and motorists travelling early should expect slower journeys while the fog clears.
