Los Angeles County Fire Department crews were battling the Azusa fire named the Peak Fire on Tuesday afternoon as evacuation orders went out for zone AZU-MCO1. The brush fire was reported around 1:09 p.m. in the area of N. San Gabriel Canyon Road and N. Ranch Road.
The blaze was described as approximately 15 acres. Aerial footage showed water-dropping aircraft over the scene while crews moved into the adjacent neighborhood to enforce the evacuation order.
Zone AZU-MCO1
Residents in zone AZU-MCO1 were told to leave as the fire response widened beyond the burn area itself. For people in that zone, the practical change was immediate: access and movement in the area were being controlled while crews worked the fire line and supported evacuation.
The order came while a Red Flag Warning had been issued in Southern California. Forecasters said a moderate to strong Santa Ana wind event was expected to increase critical fire danger through Saturday, keeping conditions primed for rapid fire growth even after a fire starts small.
Peak Fire in Azusa
That was the sharp edge of this incident. The fire was relatively small at about 15 acres, yet it was serious enough to trigger an evacuation order and draw aircraft into the response, which is the kind of mismatch residents notice first: a modest acreage count, but a response built for something that could change quickly.
What mattered for anyone in or near Azusa was not the number alone, but the combination of the location, the wind, and the order already in place. With critical fire danger expected to stay elevated through Saturday, residents in the evacuation zone had one clear priority: follow the evacuation order and stay clear of the response area.
