LA fires live updates: 9 people charged with looting, DA says

Pedro Pizarro, the president and CEO of Edison International, told "Good Morning America" on Monday that the company cannot yet rule the possibility that its energy infrastructure played a role in sparking wildfires now raging around Los Angeles.

Fire agencies are investigating whether Southern California Edison -- a subsidiary of Edison International -- infrastructure sites caused fires in areas devastated by the Eaton and Hurst wildfires.

"You can't rule out anything ever until you can get your eyes on the equipment," Pizarro said.

"Typically, when there's a spark created by equipment, we will see the electrical anomaly -- we haven't seen that," Pizarro said of a possible incident involving Edison infrastructure and the Hurst Fire burning outside of San Fernando.

"That said, we have not been able to get close to the equipment," he continued. "As soon as we can get close to it, we'll inspect and be transparent with the public."

"We may find something different," Pizarro added.

Pizarro said Edison also recorded damage to equipment at the site of the Eaton Fire in the mountains north of Pasadena. "We don't know whether the damage happened before or after the start of the fire," he said.

Pizarro said that Edison International will be shutting off power to some California residents as a precaution amid red flag warnings.

"We have about 450,000 customers who we've warned they may need to have their power shut off," Pizarro said.

Weather officials have issued a "Particularly Dangerous Situation" red flag warning for western Los Angeles County and most of Ventura County beginning on Tuesday at 4 a.m. into Wednesday at noon.

Winds are forecast to be strong enough to potentially cause explosive fire growth.

A new Santa Ana wind event is forecast Monday through Wednesday with the strongest winds Tuesday into Wednesday.

On Monday morning and the rest of the day, winds will begin to pick up in the mountains and higher elevations, gusting 20 to 30 mph, locally as high as 50 mph.

By Tuesday morning at 4 a.m., when the "PDS" conditions begin, gusts in the mountains are expected to near 70 mph possibly and humidity could be as low as 8% for some of the area.

At least 68 people have been arrested in fire evacuation zones, according to law enforcement officials, as police work to secure devastated parts of Los Angeles and firefighters continue to battle wildfires.

The Los Angeles County Sheriff's Department said it recorded 29 arrests -- 25 in the Eaton Fire area north of Pasadena and four in the Palisades Fire area in western Los Angeles.

The Santa Monica Police Department reported 39 arrests in evacuated areas in its jurisdiction on Saturday night, including 10 for burglary and six for possession of burglary tools. None of those arrested lived in the area, the department said.

Gov. Gavin Newsom warned late Sunday that the week was beginning with a forecast for a "Particularly Dangerous Situation" for new wildfires, even as the firefight against the several fires still burning continued.

"Emergency responders are ready tonight. Pre-positioned firefighters and engines are spread around Southern California," he said on social media. "Stay safe. Be ready to evacuate if you get the order."

The warning, which comes from the National Weather Service, says that the fire risk is high in Santa Barbara, Ventura and Los Angeles counties amid strong winds, a lack of recent rainfall and relatively low humidities. The warning begins Monday night and runs through Wednesday morning, the service said.

It's is the fourth of its kind in three months, Newsom said. The first came ahead of the Mountain Fire in Ventura, which destroyed 243 structures. The second preceded the Franklin Fire in Malibu, which destroyed 20 structures.

And the third preceded the Palisades and Eaton Fires, which have now destroyed thousands of homes and structures, he said.
