SANTA MARIA, Calif. (AP) — Rising temperatures on Wednesday posed new challenges for firefighters who have made incremental progress against a massive wildfire in central California that has injured four people as it has become the biggest blaze in the state so far this year.

The Gifford Fire rages to more than 82,000 acres of destruction. The photos from the frontlines show how intense the California wildfire has become.

A massive wildfire burning in eastern San Luis Obispo and Santa Barbara counties is now California’s largest wildfire of the year, according to Cal Fire.
