THE Met Office has issued a weather warning of fog.

A yellow weather alert - meaning be aware - has been issued for Dorset, Bournemouth and Poole.

It is valid from 7pm tonight until 11am on Thursday morning.

The Chief Forecaster said: “Fog patches are likely to form during the early part of Wednesday evening, becoming more widespread overnight with the visibility falling below 100 metres in places.
