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): Wall Street set a record last week for the longest "Bull" run in US Stock Market history, topping 3,400 days of growth. Now, financial experts are saying it won't last forever and advising clients to prepare for a downturn."You have to expect at some point, we're due," says Dennis Brewster of SagePoint Financial. "I think everybody's almost forgotten, look at earlier in the year, how sharp the markets broke back in February. So it wouldn't be unusual to see any of those declines coming up later this year or early next year."Brewster says he doesn't expect anything as drastic as 2008, but he still says investors should take a few steps to safeguard their earnings and even make the downturn work in your favor.A lot of it, he says, depends on how close you are to retirement."When you look at the year to year returns, they're all over the board. When you look at the 20-30 year returns they're very close," says Brewster. "If you're younger and have 20-30 year horizons, the day to day gyrations are almost noise to you. But if you're getting closer to retirement or in retirement, then you have to be more careful."'Brewster looked up numbers from the S&P 500 for the last 20 years. He says someone who invested ,000 in 1998 would have lost about ,300 after the crash in 2008. But if they kept their money in until 2018, that same ,000 investment would now be worth more than ,000.He says older investors should be more conservative with their portfolios. Younger investors should increase how much they invest if the market falls, to take advantage of lower prices.As for when the correction could come, Brewster says it's too tough to predict. But he says to watch out for "triggering" events that could rattle the market, some of which may already be happening. Things like trade wars or the Federal Reserve spiking interest rates could be the kind of thing to end the Bull Run."It always goes higher than you think and lower than you think," he says. "You can't ignore it, and you try not to get swallowed by it." 2072

SAN DIEGO (KGTV) - A sailboat damaged the USS Midway Sunday.The mast of the sailboat collided with a safety net attachment on the front port-side ‘horn’ of the ship. The crash happened shortly after 2 p.m. according to Harbor Police.The mast of the sailboat snapped off. There was minor damage to the safety nets of the Midway.“I thought something fell off the flight line, I didn't think a boat would crash into the Midway,” said Craig Wiener, who was touring the Midway at the time of the crash. “We were looking out the little port windows, and you see the mast falling off into the water."Harbor patrol says no charges are expected and attributed the crash to inexperience on the part of the person steering the sailboat.  Eight people were onboard the sailboat, and none of them were hurt.“He didn't realize how close he was and how tall his mast was and it was too late and the wind pulled him in,” Wiener said. 945

  

SAN DIEGO (KGTV)-- Flags are being flown at half-staff around the country today to honor fallen firefighters and to promote emergency preparedness. Sunday is also the kick-off of National Fire Prevention Week.Cher Smith's home in Crest has a 360-degree view of nature. It's beautiful to look at, but dangerous during fire season. "Somebody is throwing a cigarette out, sparks from a car, whatever," Smith said. "There's always that fear that something is all of a sudden going to cause a fire to get out of control."In the last month, she and her son-in-law spent hours clearing up the dead brush on her 2.5 acre property. "We just barely made a dent on what needed to be done," Smith said. Smith said she couldn't afford to pay a landscaper to finish the job, but that all changed when she looked out her window earlier this week. "They are all up there like ants on the mountain bringing down the brush," Smith said. She saw CALFIRE and inmate fire crews working earnestly, with shovels in hand, to create a safe, defensible space. The space won't just create a defensible space for Smith's home, but for the entire Crest community. "I said, 'You have no idea how jazzed I am that you guys are doing this for us!'" Smith said enthusiastically. That's because just last month, she watched the Dehesa fire, creeping up toward her home. Also, back in 2003, her son-in-law lost his childhood home to a wildfire."A lot of people in Crest had their homes burned, so I think people are on high alert and sensitive to the dangers," Smith said. That's why to kick off National Fire Prevention Week, she wants to thank the fire service for their hard work. She also wants to remind her East County neighbors to be prepared. "I like to see our tax dollars going to being proactive, rather than having them create these fire barriers after the fact," Smith said. 1861

  

SAN DIEGO, Calif. (KGTV) -- After being under a federally mandated quarantine at MCAS Miramar for two weeks, Steven and Michele Smith are finally heading home to Paradise, California."Tomorrow morning we're putting our bags on the other side of that door and we're heading on a bus to the airport. We're going to rent a car and drive 600 miles home," said Steven Smith in a Skype interview with 10News.The two would have been back home weeks ago after their planned cruise to Hawaii, but due to a coronavirus outbreak on the Grand Princess cruise ship they were on, they and all other passengers had to go into quarantine once their ship finally docked in Oakland."My sister is taking care of my birds, my daughter is taking care of my dog, and then my friend is taking care of our cat," said Michele Smith.The Smiths will complete their 14-day quarantine Tuesday and drive home Wednesday. Health and Human Services officials tell us nearly 50 people quarantined at Miramar left Tuesday, and the remaining 130 people will be discharged over the next two days. For nearly two weeks, their temperatures were checked twice a day. The Smiths mostly remained inside of a room at the Consolidated Bachelor Quarters on base, had food delivered three times a day, and only stepped outside occasionally."You can go out and walk outside, they have a fenced-in area that they keep us inside of," said Steven Smith.They were tested for COVID-19 and got their results back Monday."It was just a weird test, to have somebody shove something up your nose that far back into your nasal cavity," Steven Smith explained."But we tested negative!" added an excited Michele. "So, we are virus free 100 percent."They are thrilled to be heading home healthy and say their positive attitude and sense of humor helped get them through this unusual time.Michele leaves others just starting their quarantine with this advice, "I would recommend to all the people out there, now is not the time to bring up negative things or things that could create conflict, but just to love on each other, laugh and enjoy each other." 2101
