Fog weather warnings

Very low

Some limited geographical areas may be affected by non-persistent fog, however care should be taken in these areas, especially when driving.

Low

More widespread, locally dense fog is likely to affect significant areas but will not persist for more than 1 to 2 days. Extra care should be taken when driving through affected areas, and journeys may take longer than usual. Public transport may be disrupted, particularly air travel.

Medium

Widespread and dense fog affecting large areas may persist for many days. Travel disruption is likely, particularly as affected airports may close, and drivers should be extremely careful in affected areas.
