(FOX 11 / AP) A wildfire that burned all night in the San Gabriel Mountains above this Los Angeles suburb grew to 190 acres early Tuesday, glowing brightly in pre-dawn darkness and sending up a huge column of smoke.
The fire began shortly before 6 p.m. Monday and was mostly burning in the Angeles National Forest, away from populated areas. It was 5 percent contained just before midnight.
The glow was visible to early morning commuters traveling on Interstate 210 and other routes about 25 miles northeast of Los Angeles.
Residents of three foothill homes closest to the blaze were advised to evacuate, said Robert Brady, a fire spokesman for the U.S. Forest Service.
Although the fire was burning away from that area and into the forest, those homes and others in Azusa could be threatened if the winds change direction and push it to the south, said U.S. Forest Service spokeswoman L'Tanga Watson.
About 20 homes are near the fire, officials said.
Brady said some 200 firefighters from the Forest Service and Los Angeles County battled the flames. The fire's cause wasn't immediately known.
Monday evening, Super Scooper airplanes made drops on the fire with water sucked up from the nearby San Gabriel Reservoir. Those aircraft were grounded as darkness fell, but smaller water-dropping helicopters continued to work the fire into the night.
Although temperatures remained near 80 degrees late into the evening, Brady said weather conditions, overall, were good for firefighting. Winds were blowing at only about 5 mph, he said, helping slow the flames' progress.
Weather was expected to be not quite as hot Tuesday, but still very warm. Forecasters said an upper-level, low pressure area moving into the Pacific Northwest Tuesday night and Wednesday would cause an increasing flow of cool, moist air from the ocean onto the land.
