MISSOULA, Mont. -

Strong winds accompanying a storm Wednesday afternoon forced fire managers to pull firefighters off the West Mullan fire burning north of Superior.

Fire information officer Pat McKelvey says the fire didn't receive any moisture Wednesday afternoon or evening, but the wind helped push the fire from 1,800 acres to 3,600 acres, or about 5.6 square miles.

The fire moved northeast toward the Bonneville Power Administration line.

More than 50 homes remained under evacuation and Mineral County officials put more residents on ore-evacuation notice.

More crews arrived to help the firefighting effort and crews pulled off the lines were expected to return Thursday morning.

The Mineral County Fairgrounds has been opened to house animals and livestock, but owners are responsible for food and water.
