HAILEY, Idaho -- Fire officials say a wildfire pushed by strong gusts and fed by dry timber and brush made a push north and forced more evacuations near the Idaho resort town of Ketchum.

Still, firefighters made some progress on the Beaver Creek Fire Saturday as five more hotshot crews arrived to slow the march of flames toward homes in the affluent town and neighbouring Hailey.

The fire grew to 144 square miles Friday night and pushed north of Ketchum near U.S. Highway 75. Officials will have a better sense of the size after flyovers with infrared cameras Saturday night.

So far, 2,300 residences have been evacuated since the lightning-ignited fire began Aug. 7.

Elsewhere, in northern Utah, about 10 homes were destroyed when a wildfire raced through the community of Willow Springs late Friday.
