A fast-growing wildfire has broken out north of Los Angeles, fire officials said, while two large blazes in the metropolitan area have been under control for more than two weeks.
Wildfires engulfed the hills near Caustic Lake on Wednesday, spreading rapidly and covering more than 9,400 acres (3,800 hectares) in just a few hours.
Evacuation was ordered for 31,000 people around the lake, which is located 56 kilometers (35 mi) north of Los Angeles, and is near the city of Santa Clarita.
The United States Forest Service said the 700,000-acre (2,800sq-km) park in the San Gabriel Mountains was closed to visitors.
The California Department of Forestry and Fire Protection (Cal Fire) said the two deadly fires that ravaged Los Angeles became more contained as new fires broke out.
Since the two fires broke out on Jan. 7, they have burned nearly an area of ​​Washington, D.C., killing 28 people and damaging or destroying about 16,000 structures, Cal Fire said.
Private forecaster AccuWeather has estimated damages and economic losses at more than $250bn.
