A large woodland and grass fire has broken out in Macclesfield Forest.
Ten fire engines and specialist units are tackling the blaze after crews were called to Hacked Way Lane, near Macclesfield, Cheshire, just after 16:00 BST.
Footage shared with the shows a helicopter dropping water on the fire, with United Utilities providing the aerial support.
Cheshire Fire and Rescue Service urged people to stay away, saying visitors have continued to arrive while emergency crews work nearby. It added conditions could change rapidly and warned of heavy smoke, with people advised to keep their windows and doors closed while drivers have been asked not to block routes needed by emergency vehicles.
