What to Know
- The Silverado Fire began Monday in eastern Orange County and quickly spread west, forcing evacuations in Irvine.
- Two firefighters who suffered burns remain hospitalized.
- Southern California Edison said it is investigating whether an equipment failure sparked the fire.
Tens of thousands of eastern Orange County residents remain under evacuation orders Tuesday as winds threaten to fan an 11,200-acre brush fire.
The Silverado Fire began Monday morning and spread behind a cold wind blast from the desert that raced ferociously through Southern California’s mountain passes. Flames quickly spread near Irvine and Lake Forest.
Containment was at 5 percent.
The strongest winds Tuesday are expected during the morning. Gusts will diminish into the evening.
About 91,000 residents have been evacuated. A homeowner in Lake Forest said the wind appeared to be shifting flames away from his neighborhood Tuesday morning.
“I’m in a pretty safe zone,” he said. “This burned about seven years ago, so the fuel is probably a little bit lower than it was back then. We had a lot of embers drop on the house back then.”
Two firefighters, ages 26 and 31, suffered second- and third-degree burns Monday. Both hand crew members remained hospitalized early Tuesday.
Late Monday, Southern California Edison told California officials that a lashing wire may have contacted its overhead primary conductor, sparking the fire. Edison sent a letter to the California Public Utilities Commission Monday night acknowledging it had overhead electrical facilities in the area where the blaze broke out.
“We have no indication of any circuit activity prior to the report time of the fire, nor downed overhead primary conductors in the origin area,” SCE said in the letter. “However, it appears that a lashing wire that was attached to an underbuilt telecommunication line may have contacted SCE’s overhead primary conductor which may have resulted in the ignition of the fire.”
The Silverado Fire started at about 7 a.m. Monday in the area of Santiago Canyon and Silverado Canyon roads. No structures have burned.
High winds compromised the aerial firefighting effort. All aircraft we’re grounded by mid-morning due to gusts, which rendered water drops ineffective while also making flying treacherous for pilots. Winds of 20 mph-40 mph were reported, with gusts up to 60 mph.
“Unfortunately, the winds are going to be an issue again,” said NBC4 forecaster Belen De Leon. “Fire danger is still an issue today.”
Red flag fire conditions are expected through Tuesday. Morning gusts were clocked at about 60 mph.
“This is a tough fire,” Fennessy said. “We’re experiencing very high winds, very low humidity… Any time winds are that bad you can’t fly, and that certainly has an impact on both hand crews and bulldozers and firefighters at the end of those hose lines.”
The Silverado Fire is one of two major wildfires burning in Southern California. The Blue Ridge Fire broke out Monday in Corona and expanded into Orange County.
Historically, October is one of the worst months of the year for wildfires in California, due in large part to months of dry conditions and strong fall winds. But in 2020, the state has already seen five of its six largest wildfires during August and September.
As of Sunday, there were 20 major wildfires burning in California. More than 4 million acres have burned this year, far surpassing any previous yearly total on record.
Irvine opened eight facilities to shelter evacuated residents and several quickly filled up. City officials were working with the American Red Cross to provide overnight shelter for residents with no place to go.

Aerial footage from the scene showed fire crews dousing flames that appeared to have destroyed a commercial structure near the 241 toll road.
The southbound Riverside (91) Freeway to the Foothill Transportation Corridor (241) toll road was closed and the northbound 241 was closed at Portola.
The Eastern Transportation Corridor (133) northbound was closed at Irvine and eastbound Chapman-Santiago Canyon was closed at Jamboree and Santiago Canyon from Silverado Canyon was closed, according to California Highway Patrol Officer Florentino Olivera.
The Riverside (91) Freeway was also closed in the area north of the 241 Freeway.
OCFA officials said the flames jumped the 241 Freeway shortly after 9 a.m. Monday
The fire sent a major plume of smoke over the entire region, creating unhealthy air across a wide area. The Orange County Health Care Agency urged residents in affected areas to stay indoors, limit outdoor activity, keep windows and doors closed and run air conditioners to filter the air.
