The Hughes Fire has now burned 8,096 acres in Los Angeles and Ventura counties since igniting late Wednesday morning near Castaic Lake, according to Cal Fire. As more than 400 firefighters responded to the scene, an air tanker and four helicopters attacked the blaze from the air, preventing it from jumping Interstate 5, officials said.

Mark Walter Family Foundation and Los Angeles Dodgers Foundation have provided an initial commitment of $100 million.

The death toll from wildfires that have been raging near Los Angeles since early this month rose to 29 on Monday, officials said.
