The fire burned about three acres before firefighters were able to get the flames under control, with help from water-dropping helicopters and a Super Scooper airplane.
The blaze was first reported shortly before 5 p.m. Wednesday in the area of the 500 block of North Durfee Avenue.
Even with forward progress stopped, firefighters maintained a substantial presence at the site amid the heavy Santa Ana winds which continue to present a serious fire risk to all of Southern California.
No injuries or structure damage were reported. The cause of the fire was under investigation.
