A yellow warning of fog has been issued across Dorset this morning.

Motorists are therefore being encouraged to take extra care on the roads.

The warning is in place until 10am today.

Widespread fog will be dense in places this morning,with visibilities locally of less than 50 m, giving difficult driving conditions and prolonging journeys.

The chief forecaster's assessment read: "Moist air pushing up from the south has led to the formation of widespread mist and fog.

"Whilst visibilities will be more than 100 or 200 m for the most part, locally they are less than 50m.

"Conditions will gradually improve this morning."

People are also being urged to take care on Saturday as strong winds are forecast.

The Met Office has issued a yellow 'be aware' weather warning valid for the south of England, including Dorset, from 4am to 11.59pm on Saturday.

A spokesman said: "A spell of strong southwesterly winds is expected. Some coastal routes and communities are likely to be affected by large waves, with potential for flooding of properties.

"Some transport disruption is likely across the warning area, with delays to road, rail, air and ferry transport. Short term loss of power and other services is also possible."
