Zero percent is under control, writes The Los Angeles Times about the fire that is 7,000 hectares in size.
The fire started on Thursday and is still raging in San Bernardino National Park. On Sunday, the fire spread rapidly in the very dry forest area.
Over 600 firefighters are battling the fire, and three people are reported to have been injured in the work.
A thunderstorm is expected on Sunday evening, which is believed to worsen the situation, warns the fire department. On the one hand, lightning may cause new fires, and on the other hand, the bad weather prevents planes from helping with the extinguishing work.
They are trying to fight the fire in steep terrain that is almost impossible to reach from the ground, says Dave Munyan of the national weather service to LA Times and notes:
The weather is really not cooperating with the firefighters.
A heatwave has plagued southern California for the past week, and on Friday, 44 degrees were measured in central Los Angeles.
The coming days are expected to be slightly cooler, but still with temperatures above 30 degrees during the day.
Governor Gavin Newsom has declared a state of emergency and promised federal aid to facilitate both the firefighting efforts and those who may lose their homes or businesses.
