The single-family home was discovered within the perimeter of the 6,819-acre wildfire, Cal Fire said. Firefighters said the structure was believed to have been abandoned due to its remote location and lack of access routes.

"Winds are expected to increase in the afternoon with gusts up to 20 mph. Crews have been seeing minimal fire activity. Smoldering may continue from inside the fire area."
