CALIFORNIA (USA Today) -- A wildfire burning north of Los Angeles raced out of control Thursday, burning two homes, forcing evacuations and shutting down schools.

Three people were in custody, accused of accidentally sparking the blaze.
The fire, near Glendora about 30 miles northeast of downtown Los Angeles, started early Thursday and quickly grew to more than 1,700 acres, authorities said. Los Angeles County Fire Chief Daryl Osby said one person suffered minor injuries.
"Unfortunately, we were unable to save two homes," Osby said. "We were able to save hundreds if not thousands of homes."
Glendora police Captain Timothy Staab said three people three men in their 20s were being held on $20,000 bail each, accused of recklessly starting the fire. Staab said one of the men admitted they were tossing paper in a campfire when the wind kicked up.
"He was apologetic," Staab said.
U.S. Forest Service spokeswoman L'Tanga Watson said damage assessment teams were working with Los Angeles County officials. "The good news is that the winds have eased and the fire is slowing down. We don't have it controlled or contained, but we are definitely getting a handle on it."
More than 550 firefighters, eight helicopters and seven planes were battling the blaze. Almost 100 fire trucks were being used, many of them to protect neighborhoods from the blaze, Deputy Fire Chief John Tripp said.
The Glendora Police Department said three people were in custody in connection with the blaze, but provided no details. The Forest Service listed the fire's cause as "under investigation."
The Glendora school district closed five schools; Citrus College also canceled classes.
Helicopter TV footage showed an unknown number of homes burning. When local resident Rita Abouchedid went to bed Wednesday night, there was no fire. She told the Los Angeles Times she awoke Thursday morning to the sound of neighbors pounding on her door, warning her to leave.
She said she drove her three teenagers to their grandparents' house and then drove back to her home.
"I thought, 'I feel like an idiot, driving back up when everyone's leaving,'" she told the Times as she stood on her roof. Family members and friends helped the couple fight the approaching flames. "My husband didn't want to leave, we couldn't leave him alone."
Palm trees around her were catching fire, and electrical transformers were sparking. "It's like a dream, it isn't real," Abouchedid said.
The notorious Santa Ana winds, linked to the spread of Southern Californians worst wildfires, had picked up at daybreak. Temperatures were the 80s, warm for the season.
California has seen rainfall below normal levels for months. Red flag warnings for critical fire weather conditions were posted from Santa Barbara County south through Los Angeles to the U.S.-Mexico border, along the Sierra Nevada, and in areas east and north of San Francisco Bay.
Fires that struck windy areas of the state earlier in the week were quickly quashed by large deployments of firefighters, aircraft and other equipment before the flames could be stoked by gusts into major conflagrations.
Spawned by surface high pressure over the interior of the West, the Santa Anas form as the cold air flows toward Southern California, then speeds up and warms as it descends in a rush toward the coast. Some of the most extreme gusts reported by the National Weather Service topped 70 mph.
