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

A wildfire in Southern California sparked early Thursday evening and grew quickly in size overnight. Hundreds of firefighters continue to fight the new Canyon Fire that has spread to around 5,370 acres.

The fire has scorched an estimated 5,400 acres north of Los Angeles, but Ventura County officials said firefighters were making “good progress in suppressing the blaze.”
