A warning has been issued this morning due to fog.

Patchy fog will result in difficult driving conditions in places during this morning.

Drivers are warned to expect slower journey times with delays to bus and train services possible.

Patches of fog will continue to form with the visibility in some places falling below 100 metres. With temperatures also below freezing, icy patches will be an additional hazard on untreated surfaces.

Fog will thin and clear from most places later in the morning.

The warning is expected to end at 11am.
