HUNTINGTON, Ore. (AP) — A wildfire that started Wednesday off Interstate 84 in eastern Oregon grew to nearly 11 square miles in just one day.

Interstate 84 was temporarily closed between Ontario and Pendleton and the city of Huntington has told its residents to be ready to leave if the fire comes closer. Officials said early Thursday the the interstate had been reopened in both directions.

Vale District Fire Management officer Bob Narus says fire officials are optimistic they can prevent an evacuation related to the Lime Hill Fire. The cause of the blaze is still being investigated.
