Wolfe emphasized that the growth of the fire was largely due to strategic burnouts performed by firefighters to control the blaze.
Today they'll work to expand containment.
As for residents in the area, Wolfe warned not to get too complacent.
"We still want them to be prepared," Wolfe said. "If they have medication, if they have family members, make sure everything that is important can be put in cars and moved."
