LOS ANGELES (AP) — A wildfire that has burned nearly 36 square miles (93 square kilometers) in Southern California’s Santa Ana Mountains is showing renewed activity despite being 100 percent contained during the weekend.

The Orange County Fire Authority says the flare-up Monday morning is well within the area scorched by the so-called Holy Fire and is currently not a threat because it is in unburned fuel surrounded by areas that were already burned.

The Cleveland National Forest tweets that the smoke will be very visible to surrounding communities.

Aircraft and crews have been dispatch.

The fire broke out Aug. 6 in the area of Holy Jim Canyon and a local resident has been charged with arson.
