Firefighters reported some progress Tuesday against a gigantic blaze on the edge of Los Angeles, but warned that this one might be just a preview of even greater dangers ahead.
The peak Southern California fire season hasn't even started yet.
The worst fires typically flare up in the autumn, when ferocious Santa Ana winds can drive fires out of wilderness areas and into suburbs.
As a result, Southern California could be in for a long wildfire season.
The Santa Anas are so devastating when they carry fire because they sweep down from the north and reach withering speeds as they squeeze through wilderness canyons and passes and plunge into developed areas.
Even though winds have been mostly calm since the blaze began along the northern fringe of Los Angeles and its suburbs, the flames have spread over 190 square miles (492 square kilometres) of forest in a week.
Some 12,000 homes remained threatened as 3,600 firefighters and aircraft battled the blaze across a 50-mile (80-kilometre) line.
Thousands of people have been evacuated and the names and addresses taken of those who refuse to leave their homes.
"That is 6300 evacuations and the people that are not leaving what we are doing, is we are jotting down their names and their addresses, so we can notify the next of kin - if we need to," said Steve Wintmore of the Los Angeles County Sheriff's Department.
But it was not the only significant blaze in Southern California.
The big fire, known as the Station Fire, was just 5 percent surrounded, but fire chiefs said that figure could double by the end of the day.
Weather was more humid, which helps brush resist burning, but the downside was a possibility of dry lightning. Some sprinkles were reported, but no significant rain.
Officials were worried about the threat to a historic observatory on Mount Wilson northeast of Los Angeles.
But on Tuesday, the flames near the facility appeared much tamer than the infernos that boiled up out of the mountain range in previous days.
Authorities could not immediately ascertain whether the fire at the top of Mount Wilson was the result of the overall advance of the blaze or backfires set by fire crews.
From a helicopter above the 5,700-foot (1,737-metre) peak, small flames could be seen creeping under trees.
Firefighters had doused the peak with flame retardant before withdrawing when the fire appeared to be too dangerous.
Mount Wilson is home not only to the observatory but numerous television, radio and cell phone antennas serving the metropolitan area.
The fire is one of hundreds of wildfires in a season that usually does not gather steam until October, when the Santa Ana winds arrive.
This year's destructive Southern California wildfires began in May, when 80 homes were destroyed and more than a dozen others were damaged in the Santa Barbara area. "
Wind has not been a problem in the current fire, but drought has.
The region is in the midst of a three-year drought, and the tinder-dry forest is ripe for an explosive fire.
