Weather warnings continue to blight Gloucestershire for the start of the working week with a yellow warning for fog put in place by the Met Office.
Clear skies on Sunday night will allow patchy fog to form, with thicker patches expected to become more widespread across the county overnight.
The fog is expected to be dense in places and persist well into Monday.
As a result, it could create difficult driving conditions, with visibility likely to fall below 200 metres.
Fog is also likely to be slow to clear on Monday, and may locally persist all day, before becoming more extensive on Monday evening.
