DW Fire tells us: “We were called to the A338 southbound at 1.34pm today (17 August) for a car fire that had spread to an area of adjacent heath.
Due to the conditions, the fire has now spread to two areas of heath off the northbound carriageway.
We have crews on scene from Springbourne, Wareham, Lymington, Christchurch, Poole, Redhill Park and Ferndown, together with water carriers from Ringwood and Poole.
Dorset Police have closed both carriageways while firefighters tackle the blaze.”
