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)- The San Diego Fire-Rescue Department and local military members are working to put smiles on the faces of kids this holiday season. The 2019 Toys for Tots drive started Sunday. The fire department is partnering with the U.S. Marine Corps Reserve. They have been collecting toys for more than 15 years. Through December 16, all San Diego Fire facilities will be collecting toys and books. The items must be new and unwrapped. Toys for Tots is in its 71st year. U.S. Marines distribute the donated items to the children each year. Since 1947, more than 244 million children have benefited from the toy drive. Local Marines are asking for volunteers to help distribute the items, Monday through Friday, from 9a to 3 pm. The distribution site is at 9955 Pomerado Road. 790

SAN DIEGO (KGTV)- Students say they are nervous about what’s next for the Art Institute of California San Diego.Last July, the organization’s parent company announced they were no longer enrolling new students at the Mission Valley Campus. The school’s federal funding is now in jeopardy. The Department of Education has decided to stop providing financial aid to the institution’s parent company, Argosy University. “They tell me everything is going to be fine, but in reality, it's not,” says student Nicholas Roberts. He is just three months away from getting his degree for the Art Institute of California San Diego. “(I’m) a little afraid because my family and myself kind of rely on me finishing this degree.”Classes are still in session at the Mission Valley Campus.A letter was sent out to students from the institution, saying in part: “We continue to work with our accreditors, state regulators and the U.S. Department of Education to identify the best path forward for our students and are working with them to ensure students know their options.” 1066

  

SAN DIEGO (KGTV)- Two years ago the Norton Sound was docked in San Diego Bay and burned for several days. Now, San Diego is hiring an outside consultant to look into the cargo fire. San Diego Fire gave 10News a statement Friday. They didn’t offer specifics about what the consultant might recommend, but say the focus is to determine if any additional equipment or training is needed when dealing with emergencies on the bay. Back in 2017, Harbor Police told 10News, “It was to my understanding that the furthest a firefighter made it was 6 feet before they started getting pushed about the fire.” Looking back, even businesses remember how horrible the smoke was over the days the fire burned, “People stopped sitting outside and employees complained about it affecting their health.” says Edgewater Grill assistant manager, Sergio Velasco. While the smoke bellowed out of the ship for nearly a week, no one was injured and the fire stayed contained and didn’t spread to any other structures. The city tells 10News the study is being done by Citygate and should be complete in the fall of 2019. 1104

  

SAN DIEGO (KGTV): A new study shows that young adults are seeing a spike in deaths from liver disease related to binge drinking. It's especially dangerous in California, where high alcohol content drinks are popular.The study, published this month in the British Medical Journal, says that the number of 25- to 34-year-olds who died annually from alcohol-related liver disease nearly tripled between 1999 and 2016, from 259 in 1999 to 767 in 2016, an average annual increase of around 10 percent.It cites binge drinking as a leading cause, because of rising rates of alcohol consumption between 2002 and 2012.It's especially bad in California, which the study says was among the top five states for those types of deaths.Local experts say the kind of alcohol we drink may be to blame, as craft beers tend to have higher concentrations of alcohol."If someone was having highly concentrated alcohol, then they're consuming more drinks per hour," says Dr. Rohit Loomba, with the UC San Diego Health Liver Center. "That will have detrimental effects on the liver, for sure."The CDC recommends no more than 1-2 drinks per day for "moderate" drinking. Binge drinking is defined as 4 or more drinks over 4-6 hours. Loomba says you may hit the "binge" point in fewer drinks if what you're having is stronger.For example, a Bud Light has just 4.2% alcohol by volume. Craft beers often have 6% or higher, so one craft beer may be as much as 2 or 3 other drinks."That quantity of alcohol intake over years definitely will contribute to higher risk for liver disease," says Loomba.He says people should ask themselves four questions to determine if they are drinking too much:1. Have you ever cut down on drinking? 2. Would you be annoyed if somebody asked you to cut down on drinking? 3. Do you feel guilty after drinking excessively over a weekend? 4. Do you need an "eye-opener" in the morning to get to work?Dr. Loomba says if you answered "yes" to 2 or more of these questions, you should talk to your doctor to discuss treatment.He also says obesity combined with alcohol can lead to more severe liver problems and even death. People with diabetes or who are overweight multiply their risk of the disease."If you're obese, you not only should restrict your alcohol, but you should try to lose some weight as well," says Loomba.The study says the financial crisis may have led to more binge drinking in the past decade, as young adults turned to alcohol to cope with financial stress. Researchers found the rise in alcohol-related deaths overlaps with rising rates of binge drinking from 2002 to 2012 observed across much of the U.S.The good news, according to the study, is that many liver diseases are preventable and reversible."Once you stop alcohol use, you can reverse complications related to it in the majority of cases," says Dr. Loomba. 2882
