The Canyon Fire near Lake Piru rapidly spread Thursday. See fire map, the location of the LA area fire and where other fires are burning in the state.

CalFire reports the Canyon Fire which began at around 1:25 p.m. on Thursday, Aug. 7, is now burning east with a rapid rate of spread in light to medium fuels.

Temperatures in the area are near 100 degrees and humidity as low as 15 percent. The southern part of California has seen very little rain, drying out vegetation and making it "ripe to burn," the National Weather Service (NWS) for Los Angeles warned.
