The Met Office has issued a yellow weather warning for fog for some parts of Wales, with visibility dropping to just 50m in parts. The warning was issued before midnight on Tuesday and is in place from 3am on Wednesday, February 8, to 11am on the same morning.
The warning reads: "Patches of freezing fog are likely to become more widespread towards dawn on Wednesday, particularly along river valleys and across eastern and southern England, with the visibility as low as 50 to 100 metres in a few places. Fog will slowly thin and clear later on Wednesday morning."
The yellow weather warning covers south east Wales, including Cardiff. It comes after the forecaster warned that a sudden stratospheric warning was expected to hit the UK at the end of the month bringing with it the possibility of cold, frosty weather. You can read more about that here.
