An evacuation warning was issued Thursday night for residents of 20 homes in an area northeast of Groveland threatened by a wildfire that has burned 100 acres in Tuolumne County since Wednesday.
Daniel Berlant, a spokesman for the California Department of Forestry and Fire Protection, said the warning means evacuation is not mandatory.
The Graham fire started about 10 p.m. Wednesday. Officials said it continues to smolder and creep in the brush. Although the weather Thursday was favorable, with temperatures in the 80s, Berlant said, the extremely dry conditions continue to make firefighting difficult. He said the fire does not pose a threat to traffic in or out of Yosemite National Park.
