The Gifford Fire has scorched more than 83,000 acres of California's Central Coast, becoming the state's largest wildfire of the year so far. The massive wildfire burning in eastern San Luis Obispo and Santa Barbara counties was 9% contained as of Wednesday, Aug. 6, according to the California Department of Forestry and Fire Protection.

Rising temperatures on Wednesday posed new challenges for firefighters who have made incremental progress against a massive wildfire in central California that injured four people as it became the biggest blaze in the state so far this year.

Fire managers for the U.S. Forest Service put Gifford at 49,761 acres (77 square miles), with 3% containment. Three people were reported injured: a civilian who was burned, and two contractors who were injured in an off-road utility vehicle’s rollover.
