A Southern California wildfire is burning uncontrollably a day after it ignited, scorching 30,000 acres.
The brush fire is 0% contained as of Wednesday morning, according to the San Bernardino National Forest.
Authorities have warned more than 82,000 residents in San Bernardino County to evacuate from the fast-moving fire that began Tuesday; 34,500 homes are in the evacuation area.
More than 1,300 personnel are on the scene responding to the blaze as well as 152 engines, 18 crews, 10 air tankers and eight helicopters, according to the San Bernardino National Forest.
The massive fire, called Blue Cut, prompted Gov. Jerry Brown to declare a state of emergency in the area.
“This is a very quickly growing wildfire,” a San Bernardino National Forest statement said, urging residents to follow evacuation instructions.
Fire authorities warn of “imminent threat to public safety, rail traffic and structures” in the affected areas.
The blaze started about 10:30 a.m. Tuesday in Cajon Pass, a mountain pass between the San Bernardino Mountains and San Gabriel Mountains. The size of the fire is roughly 28 square miles.
The area of the fire is about 70 miles east of Los Angeles, affecting Cajon Pass, Lytle Creek, Wrightwood, Oak Hills and surrounding areas.
On Tuesday, six firefighters were trapped by the wildfire but found shelter at a nearby structure, according to the San Bernardino County Fire Department. Two suffered minor injuries but later returned to the fire line.
The fire quickly scorched up the dry hills as winds carried the embers. It fed on the thick, parched brush, and engulfed an unknown number of homes and structures, according to fire officials.
One resident told CNN affiliate KABC-TV in Los Angeles about the flames surrounding her house.
“We had to keep the windows up because we couldn’t breathe. The smoke was so thick, and as soon as the smoke cleared, we could see that everything was gone,” said Crystal Armstrong, who lost her home.
Firefighters implored residents to evacuate, saying that refusing to do so puts lives at risk.
Aerial views showed the mountains covered in plumes of smoke.
Drought-stricken California has been hit with waves of wildfires this summer, fueled by dry conditions, heat and dead brush.
Before the Blue Cut Fire, 8,000 firefighters had already been battling eight large wildfires across the state.
