The Met Office have issued Merseyside a yellow severe weather warning for Fog, the warning is in place from 12:05am – 11:00am Sunday.
Fog patches are expected to form on Saturday evening, becoming locally dense by Sunday morning.
Not everywhere will see fog, but where it does form visibility is likely to fall below 100 metres, perhaps locally below 50 metres in a few spots.
The public should be aware of the potential for some difficult driving conditions and minor travel disruption especially at Liverpool Airport.
A forecaster at the Met Office has said: “Whilst some areas of cloud are likely to persist overnight, many places will see spells of clear sky.
“Where this does occur, conditions are favourable for fog formation.
He added: “This is likely to be patchy but sometimes dense – perhaps an additional hazard for drivers”.
