A wind-driven wildfire along Interstate 5 near the Grapevine exploded to more than 12,000 acres by early Sunday and had charted a path south toward the town of Castaic, prompting evacuations throughout the area, officials said. The Post fire, which originated Saturday in Gorman in northwestern Los Angeles County, was only 2% contained Sunday afternoon as high winds, low humidity and steep terrain hampered firefighting efforts.
Meanwhile, firefighters were battling another brush fire in the San Bernardino County community of Hesperia that broke out after 6 p.m. Saturday in the 18000 block of North Highway 173. That fire has burned more than 1,300 acres and was 20% contained.
