A rapidly spreading blaze in California is impacting communities in the Los Angeles area as thousands have been placed under evacuation orders, officials said.

The Canyon Fire is one of several large wildfires burning through California right now. The largest of these is the Gifford Fire, which has burnt through 99,232 acres across San Luis Obispo and Santa Barbara counties, making it the state’s largest fire of the year so far. As of late Thursday night it remained only 15% contained.

Fire officials say the blaze is threatening power lines as well as the communities of Hasley Canyon and Hathaway Ranch.
