More than 150 firefighters are back on the scene of a large forest fire in Dorset that has been declared a major incident.
Strong winds have been causing “flare-ups” at Wareham Forest, where the blaze started on Monday, the fire service said.
It said smoke had drifted as far as Bournemouth, Ferndown and Wimborne.
Investigators believe a disposable barbecue or camp fire could have been the cause of the initial blaze.
Dorset and Wiltshire Fire and Rescue Service said crews had “been trying to keep on top of the hotspots and flare-ups all day” after winds “picked up”.
About 470 acres (190 hectares) of land have so far been damaged in the fire.
People have been urged to stay away from the area.
An amber alert for wildfire also remains in place for the weekend, meaning if another wildfire was to happen it could spread quickly and easily due to the dry and windy conditions.
One third of the 3,700-acre forest is designated as a Site of Special Scientific Interest (SSSI) and is home to rare birds, plants and invertebrates.
On Wednesday, Forestry England estimated it could take the forest “decades” to recover.
