Patches of fog are already forming across the Island and will become more widespread during the rest of tonight and into the early hours of Sunday, with the visibility falling to less than 100 metres in places.
As morning approaches the fog will tend to lift onto hills, before clearing from the northwest as the breeze increases.
The yellow weather warning issued by the Met Office is in place until 06:00.
