A wildfire pushed by strong winds and fed by dry timber and brush has made a push north and forced more evacuations near a resort town in the US state of Idaho, fire officials say.
Firefighters have made some progress on the Beaver Creek Fire as five more expert crews arrived to slow the march of flames toward homes in the affluent town of Ketchum and neighbouring Hailey.
The area of the fire grew to 144 square miles on Friday night and pushed north of Ketchum near US Highway 75. Officials said they will have a better sense of the size after flyovers with infra-red cameras.
So far, 2,300 residences have been evacuated since the lightning-ignited fire began on August 7.
Elsewhere, in northern Utah, about 10 homes were destroyed when a wildfire raced through the community of Willow Springs late on Friday.
