AZUSA (CNS) - Smoke from the Ranch 2 Fire burning in Azusa has prompted the South Coast Air Quality Management District to issue a smoke warning Wednesday for parts of the San Gabriel Valley.
Winds were expected to push smoke from the fire into Glendora, Upland and Baldwin Park, the AQMD said.
The fire has grown to 4,300 acres burned and was 19 percent contained as firefighters focused primarily on extending containment lines on the north and west perimeters, according to the U.S. Forest Service.
A homeless man who allegedly set the blaze was charged Tuesday with two felony arson counts.
Osmin Palencia, who lives in a tent near the Mountain Cove community, allegedly started the blaze during an argument last Thursday afternoon, according to prosecutors.
The 36-year-old defendant is set to be arraigned Sept. 11 at the West Covina courthouse and could face up to 23 years in state prison if convicted of one count each of arson during a state of emergency and arson of a structure or forest, according to the Los Angeles County District Attorney's Office.
Palencia -- who allegedly has a prior conviction from 2015 for dissuading a witness -- surrendered to authorities on Sunday and has remained behind bars since then.
A witness who lives in a riverbed near Mountain Cove said an argument between two homeless men sparked the fire, which came dangerously close to homes.
"There were two gentlemen in the back (of a homeless encampment) fighting and they were arguing over a bike and one guy said he'd burn the other guy out, and things got escalated to where the fire started," evacuee Jimmy Pockets told NBC4. "Ran over to try to put it out, but it just took off so quick."
According to the U.S. Forest Service, dry vegetation and rugged steep terrain in the fire area "are the main cause for upslope runs. Active fire behavior continues after the afternoon inversion lift. Fuels are critically dry."
The fire made it to Pine Mountain Peak, but had not damaged radio repeaters located on the peak as of Tuesday morning, the Forest Service said. There were 456 firefighters assigned to the blaze.
No structures have been damaged, and no injuries reported.
All earlier evacuations orders have been lifted, but the following road closures remain in effect:
-- San Gabriel Canyon Road/Highway 39: closed at Northbound Hwy 39 at Sierra Madre Avenue (southbound Highway 39 is closed at East Fork Road);
-- Glendora Mountain Road: closed from Big Dalton to East Fork;
-- Glendora Ridge Road: closed from Glendora Mountain Road to Mt. Baldy Road; and
-- Santa Anita Canyon Road: closed from Arno Drive to Chantry Flats Road.
The Angeles National Forest changed its Forest Fire Danger Level from very high to extreme and moved into full fire-restriction mode, including prohibiting camp fires in developed sites. Cooking stoves, lanterns and similar devices that use propane, white gas or similar fuels are prohibited.
The fire was reported about 2:45 p.m. Thursday near North San Gabriel Canyon Road and North Ranch Road, according to the Azusa Police Department and Los Angeles County Fire Department, which called in a second-alarm response.
Gov. Gavin Newsom declared a statewide emergency Tuesday to help ensure resources to combat multiple fires burning across the state.
