Evacuations have been ordered for some Eagle County residents on Wednesday as the Derby Fire experienced "significant growth overnight."

A wildfire burning in a difficult-to-access area of the White River National Forest in Eagle County more than tripled in size Tuesday, prompting closures and evacuations, fire officials said.

Fire officials say the Lee fire is 68 percent contained, after burning nearly 138,000 acres of mountainsides, grasslands and pastures in Rio Blanco and Garfield counties. The Bureau of Land Management has reopened portions of public land, while keeping others closed to the public for the time being.
