The forecast states: "Very moist air, associated with a frontal system slowly moving northwards, is arriving into south-western parts of the UK.
"As cloud above it thins, and rain eases, this will allow a period of thick low cloud and fog to continue to develop, settle onto hills, and expand northwards with visibilities below 50m in a few places.
"Fog should gradually lift into low cloud this morning, with visibility slowly improving".
