STRONG winds and heavy blustery showers are expected to sweep across Dorset on Saturday, the Met Office has warned. 

A yellow warning, meaning 'be aware', has been issued for Dorset and much of the South West from 7am to 9pm on Saturday (August 20).

The warnings reads: "A spell of unseasonably strong southwesterly winds, accompanied by heavy, blustery showers, is expected to develop across the south of the UK later on Friday but peaking during Saturday daytime.

"Additionally the strongest winds will lead to large waves round exposed coastlines.

"Gusts of up to 45 mph inland, and 45 to 55 mph along exposed coastlines, are expected.

"Please be aware that these may lead to disruption to transport, and in view of the time of the year there is increased potential for disruption to holidaymakers and outdoor activities."

The chief forecaster added: "An area of low pressure currently forming over the mid-Atlantic is expected to intensify into an unseasonably intense feature as it tracks towards the south west of the British Isles.

"Strengthening winds on its southern flank are likely to move into southwestern areas on Friday, but the peak in wind strength will be across southwest England and south Wales at first on Saturday, spreading along the south coast of England through the course of the day."
