SAN FRANCISCO (AP) — A wildfire in California wine country that may have been caused by a high-voltage transmission line called into question Pacific Gas & Electric's strategy of selectively cutting off power in windy weather to prevent blazes, and could force it to resort to even bigger blackouts affecting millions as early as this weekend.The repeated shut-offs and the prospect of longer and more widespread ones brought anger down on the utility from the governor and ordinary customers."We will hold them to account," warned Gov. Gavin Newsom, who has repeatedly blasted PG&E — the nation's largest utility — for what he calls years of mismanagement and underinvestment that have left its grid less resilient.Twice over the past two weeks, PG&E has cut power to large areas of Northern and Central California to reduce the risk of its equipment sparking fires. Nearly 2 million people lost electricity earlier this month, and then as many as a half-million this week.But PG&E's decision to shut down distribution lines but not long-distance transmission lines may have backfired this time when a blaze erupted near the Sonoma County wine country town of Geyserville.The fire burned at least 49 buildings and 34 square miles (65 square kilometers) and prompted evacuation orders for some 2,000 people. No serious injuries were reported.PG&E said a live, 230,000-volt transmission line near Geyserville had malfunctioned minutes before the fire erupted Wednesday night, and a broken "jumper" wire was found on a transmission tower.PG&E CEO Bill Johnson said it was too soon to say whether the faulty equipment sparked the fire. He said the tower had been inspected four times in the past two years and appeared to have been in excellent condition.But PG&E stock plummeted 31 percent on the news. And the blaze could mean wider blackouts ahead."It's kind of a logical next step to say, 'Well, if our high-voltage transmission lines are at risk, we've got to shut those down too,'" said Alan Scheller-Wolf, professor of operations management and an energy expert at Carnegie Mellon University.PG&E, he said, "can't win."With dangerously high winds in the forecast this weekend, the utility said it is planning another major shutdown that could hit 2 million people throughout the region starting Saturday night and last up to two days.The preparations came as firefighters simultaneously battled flames in both Northern and Southern California: the fire amid Sonoma County's vineyards, and a wind-whipped blaze that destroyed at least six homes in the Santa Clarita area near Los Angeles and led to evacuation orders covering an estimated 50,000 people.The possible link between the wine country fire and a PG&E transmission line contained grim parallels to the catastrophic fire last year that tore through the town of Paradise, killing 85 people and destroying thousands of homes in the deadliest U.S. fire in a century. State officials concluded that fire was sparked by a PG&E transmission line.The line that failed this week is newer and should have been more robust, said Michael Wara, director of the climate and energy program at Stanford University. Its failure will probably make PG&E more cautious, which means more widespread blackouts, he said."There's going to be more collateral damage," Wara said.Turning off big transmission lines reduces the stability of the electrical grid, leading to bigger outages, Wara said. Transmissions lines also take longer to re-energize because everything connected to them must be inspected, he said.PG&E's CEO has said it will take about a decade before widespread outages aren't necessary.Minimizing blackouts will require PG&E to harden its grid with stronger poles and newer equipment less likely to fall or spark. Cameras, weather sensors and a more segmented grid would allow the company to target blackouts to areas in the most danger.PG&E began resorting to large-scale shut-offs after its equipment was blamed for several blazes in recent years that killed scores of people, burned thousands of homes and ran up billions of dollars in claims that drove the utility into bankruptcy, where it is still trying to put its finances in order.The repeated and sometimes lengthy blackouts have frustrated Californians contending with uncertainty, spoiled food and disrupted plans. Many have complained about poor communication from the power company."I feel like we're being held hostage for their failings and their incompetence," said Logan Martin, 55, of Santa Rosa.This year's fire season in California has so far been mild, with fewer deaths and fewer acres burned following two years of deadly conflagrations.Experts say it is impossible to know how much the blackouts contributed to that, but PG&E has cited numerous instances of wind damage to its equipment that it said could have caused fires if the lines had been electrified.Losing power doesn't put a huge burden on firefighters, but they need to know outages are coming so they can install generators where needed, such as pumps for retardant, said Thom Porter, chief of the California Department of Forestry and Fire Protection.Firefighters sometimes draw water from rural water systems that use electrical pumps, but there have been no reports of problems getting water to fight either of the major blazes burning in California now.___Cooper reported from Phoenix.

SAN DIEGO (KGTV)- Thieves hit a well-known business causing thousands of dollars worth of damage. Bill Howe Plumbing, located on Aero Drive, had their work trucks vandalized as thieves steal gas from the gas tanks. Fleet manager Rhett Wheeler says the business has been targeted at least three times in the last month. “Its a shock that someone will crawl underneath a car with a drill, drill a hole in a gas tank, to steal a couple of gallons of gasoline,” says Wheeler. Thieves have damaged at least 10 vehicles, costing the family-owned company around ,000 in damages. “We end up losing a truck for two or three days per occurrence,” says Wheeler. Wheeler is urging everyone, including businesses, to check their vehicles of leaking gas before driving off. The company has reported the incidents to police. Managers are also working on more security measures for the future. 889

  

San Diego (KGTV)- There are no regrets for a San Diego man who risked his life when he stumbled on a wreck in the middle of last week's rainstorm. "If you ask me, I probably would have done it again," says Victor Ruvalcava. On a rainy Wednesday morning, Dec. 4th, Ruvalcava says he saw a car flip over on Interstate 8 in Mission Valley. The young driver was ejected from the car. "I park behind his car, get out to see if he's ok, I asked him hey is there anyone else in the car. He didn't respond," says Ruvalcava. "I look towards the car, and that's when I get hit by the SUV."He was thrown about 100 feet after that SUV slammed into him. Ruvalcava spent days in the hospital with several injuries, which include a collapsed lung, broken ribs, and leg. While in the hospital, he says the young man he stopped to help, and his family came to visit him. He says they were "extremely thankful." CHP says for safety reasons, they don't recommend drivers stopping to help crash victims on a busy freeway. They should call 911. But Ruvalcava says he'd do it all over again. Family members have set up a GoFund Me account to help with his medical expenses. 1160

  

SAN DIEGO (KGTV) -Saturday was the second night five parks were under a new curfew across San Diego. Neighbors were mixed on whether it will affect crime.Police and neighbors celebrated the new curfew Friday at City Heights Square Mini Park. Police said since January 2019 there's been 217 crimes reported within 1,500 feet of the park, ranging from assault to theft.READ RELATED: Neighbors celebrate nightly curfew at San Diego parksRonald Tieken said he spearheaded the initiative, putting together a survey that he said 50 seniors in the building bordering the park responded to. He said the curfew is the first step in turning the tide in the neighborhood.Other neighbors disagree."It's probably going to up the rate of crime in this neighborhood," Ephraim Denmon III said they just need more people who will stand up to crime to fill the park. He said that or hire a security guard."If grown folks are in a grown folks park then they should let grown folks be grown folks," he said arguing the curfew takes away from the neighbors surrounding the park."You have your low income and your seniors, the seniors spend most of their time out here after midnight... Smoking a cigarette, drinking a coffee enjoying life," he said.Tieken said police are on his side, "they have high hopes that they don't have to come every 15 minutes to this park."City Heights Square Mini Park's nightly curfew is from 9 p.m. to 5 a.m. Cedar Ridge Mini Park, Montclair Neighborhood Park, North Park Community Park and North Park Mini Park have a curfew from midnight to 6 a.m. 1566
