PHOTO: The Boone Fire, which ignited Tuesday, has scorched 17,328 acres and is 5% contained as of Friday morning, CalFire reported.
More than 1,600 personnel are battling the blaze, supported by 125 engines, 44 water tenders, 13 helicopters, 28 bulldozers, and 42 hand crews.
Fire crews are working to strengthen containment lines as the fire continues to burn through grass and brush.
In the northern region, it is burning in an area previously hit by the 2020 Mineral Fire. Dry vegetation, fueled by above-average temperatures and low humidity, has intensified fire conditions.
The hot, dry weather is expected to persist through Saturday, with temperatures climbing into the high 90s. Winds are forecasted to pick up Friday afternoon, with gusts reaching 20 mph. Cooler weather is anticipated early next week.
