Fog could cause problems for travel and plans across five council areas of Wales tonight and into tomorrow morning, after the Met Office issued a yellow weather warning.

Where and when

The warning comes into force at 6pm today (Monday 9 November) and stays in place until 10am tomorrow (Tuesday 10 November). It covers:

  • Conwy
  • Denbighshire
  • Flintshire
  • Powys
  • Wrexham

What the warning means

Yellow is the Met Office's 'be aware' level. It means the fog could disrupt people's plans and their travel during that 16-hour window, so anyone with journeys planned overnight or early on Tuesday should bear it in mind.

Visibility forecast

The Met Office forecast for Wrexham, Llandudno and Brecon suggests visibility will be at its poorest early on Tuesday, falling to 690m in Wrexham at 6am.

The lowest visibility forecast across those three towns, at three-hourly intervals, is:

  • 3pm Monday – 4km (Wrexham)
