SAN DIEGO (KGTV) – Another heat wave in the forecast could leave Californians in the dark this weekend. San Diego Gas and Electric is preparing for a hot weekend as high temps are expected to cause more strain on the power grid.Energy officials are hoping to avoid a repeat of last month when rolling blackouts swept through the state for the first time in 11 years.The California Independent System Operator, or CAISO, was forced to order blackouts in response to high demand.“For the grid to operate, demand on the grid needs to be matched evenly with supply,” said Helen Gao with SDG&E.Ahead of the heat this weekend, SDG&E meteorologists are closely monitoring conditions.At this point, CAISO says they haven’t told SDG&E to prepare for rotating outages over the weekend. CAISO says it plans to issue a Flex Alert, which it says is a voluntary call for conservation.CAISO said the recent rotating outages were the result of a number of factors, including generation units being out of service, reduction of the amount of energy California was able to import from other states, and a sudden drop in wind energy.If CAISO issues a flex alert, the power company will activate their demand response programs. It encourages customers to cut back on energy use to reduce strain on the grid. Outages would only be ordered by CAISO as a last resort. On Tuesday, the State Water Resource Control Board took action to prevent more outages in the future. They’re now along four gas power plants to continue operations past 2020. They were set to stop production as California transitions to cleaner energy sources. The extended deadline is expected to ease the strain on current systems while new energy and storage resources are being built.If an outage is planned for a neighborhood, SDG&E says they try to give all customers a heads up before the lights go out.How these rolling outages workRolling outages are a method that CA ISO uses to take the load off of California's power grid. When the state says the grid is under too much stress, each utility in the state has a percentage of electricity that needs to be taken off of the grid to meet whatever wattage CA ISO is aiming for, according to SDG&E. That amount that a utility will be asked to cut during these rolling blackouts is approved with CA ISO regulators every year.SDG&E determines which neighborhoods will be impacted by creating a list of blocks. Each of those blocks accounts for about 25 megawatts of electricity. Once CA ISO tells SDG&E how much power it needs to cut, SDG&E goes down that list from the top, de-energizing blocks until it is told to stop.The next day, the company picks up where it left off on the list, so that the same neighborhoods aren't affected every night. Once SDG&E goes through its entire list, it starts at the top again.Outages can last up to an hour but can also be relatively quick. Saturday, the first block de-energized lasted for about 17 minutes, according to the company.What you can do to helpTo avoid rolling blackouts, officials say the best way is to take energy conservation seriously. Because these outages are issued by the state, conservation is needed by all Californians in these instances.Officials recommend setting the thermostat at 78 degrees, turning off unnecessary lights and electronics, and using appliances before 3 p.m. to help save power.During power shutoffs, SDG&E suggests customers turn off air conditioners, keep refrigerator and freezer doors closed, and reduce their water use due to the need for electricity to pump and process water. For electric vehicle owners, charging should be delayed if possible until after the emergency shutoffs, SDG&E said.SDG&E offers more safety tips to keep in mind during an outage here. 3805

SAN DIEGO (KGTV) - Attention is now turning to the southern border after Wednesday's border closure with Canada.On Thursday, the walkway into Tijuana was nearly empty but the San Ysidro Port of Entry remains open, for the time being. “It's going to have major implications for us, particularly for us here in Southern California, if we see a closing of the U.S.-Mexico border,” says Dr. David Shirk with the University of San Diego, where he works as a professor with an area of expertise in U.S.-Mexico relations. RELATED: Senate GOP to unveil stimulus plan that includes ,200 payments for most AmericansShirk says that if the U.S. proceeds with any closure, not only will families be separated, but there will also be a major shortage of supplies like foods that are harvested in Baja and transported north. “Something that the federal government needs to take into consideration is that our economy is critically interlinked with Mexico,” he adds.As of Thursday morning, there were only 118 reported cases of COVID-19 in Mexico. Mexican President Andrés Manuel López Obrador has been criticized in recent days for not taking enough containment measures. Video on the Washington Post's website shows him shaking hands at a big rally last Saturday and kissing a supporter. RELATED: San Diego County Westfield malls close 'majority of its operations' amid outbreakThursday, he tweeted out from a press conference to act calmly, disseminate official information and adopt hygiene measures. San Diego Mayor Kevin Faulconer said Thursday that he has requested for the State of Baja to adopt the same precautionary measures that are being taken in San Diego.This Wednesday, the Mayor of Tijuana decided to cancel events with more than 100 people. Schools in Tijuana are reportedly now closed. RELATED: San Diego and national closures, cancellations, postponements due to COVID-19Shirk says Mexico has likely been slower to respond to the pandemic out of fears over its own economy. “I think there's real concern in the López Obrador Administration that an overly drastic response to the coronavirus crisis could cripple Mexico's economy and that has to do with the fact that for the last couple of years Mexico's growth rate has basically remained about flat," Shirk. U.S. Customs and Border Protection (CBP) sent 10News a statement about any possible plans for a border closure:“What we can say right now is that the U.S. Customs and Border Protection’s (CBP) highest priority is to ensure the health, safety and security of our workforce and the American people. CBP agents and officers will maintain situational awareness while identifying individuals who have traveled from or transited through countries affected by COVID-19. CBP continues to process cargo as there has been no identified threat as it relates to cargo shipments.CBP officers use a combination of traveler history records, questioning, observation, and self-declarations to further identify individuals requiring enhanced health screening by the Centers for Disease Control and Prevention (CDC). Currently, all CBP ports of entry are following the same operational guidance as issued by Presidential Proclamations and the Department of Homeland Security. If CBP observes a traveler with symptoms of COVID-19, we will refer them to the (CDC) and or DHS medical contractors for enhanced health screening. CDC personnel are responsible for the enhanced health screening of travelers in all locations nationwide.CBP has issued guidance to all employees that outlines the current comprehensive use of Personal Protective Equipment including guidance regarding wearing masks in the appropriate circumstances.

SAN DIEGO (KGTV) — As a woman lay paralyzed from a horrific accident, police say someone was inside her car, stealing from her.  The search for that thief is now turning to San Diego County."She was the nicest, most wonderful person I've ever known," said Don Nelson.Nelson says his wife of 27 years, Terri, was on her way to pick up her father for a hospital trip in August when a truck rear-ended her car at a stoplight in Riverside.  As she lay with her neck broken, amid the commotion of bystanders and first responders coming to her aid, police say someone got into her car and stole her purse.Detectives say within days of the accident, surveillance images show her using Terri's credit cards and writing checks in her name. Nelson says as some ,000 worth of purchases were made at various businesses, from fast food restaurants and Albertsons to Costco."I think that's the lowest form of life that could possibly be. You have to be a sorry person to do something like that," said Nelson.For three months, Terri was paralyzed and on a ventilator, until she passed last week from complications from the accident.  Her husband's grief is not the only emotion that consumes him. There is also anger. He's still dealing with collection agencies seeking money from the thief's shopping spree.  During that crime spree, police believe the woman rented a Nissan Rogue in Terri's name, before the CHP pulled that car over on a highway in San Diego County. The two men inside the car have yet to lead detectives to the woman, but police hope tips from the public will."I just can't believe a lightning bolt didn't strike the person. I hope they never run into me, and I know who they are," said Nelson.Nelson believes the rented car was pulled over near downtown San Diego, but the CHP has not confirmed that. If you have any information on the case, call the Riverside Police Department at 951-353-7115. 1936

SAN DIEGO (KGTV) — As COVID-19 cases surge, Governor Gavin Newsom says he’s considering the possibility of a statewide curfew that could draw on examples from Europe and the Middle East.The restrictions could also be informed by policies in San Diego County. The state has asked San Diego County to provide information about its 10 pm mandated closure policy for restaurants, a county spokesman said.Starting Friday, Los Angeles County will enact a similar measure it’s calling a “business curfew” that will require restaurants and other non-essential businesses to close at 10 pm.“We have a lot of questions about what [a statewide curfew] looks like,” Newsom said in a press conference Monday. “Who does it impact? Who doesn’t it impact? What does a real curfew mean in terms of certain kinds of industry and business activities? That’s what we’re referring to in this space.”Newsom seemed to suggest a statewide curfew isn’t a foregone conclusion, but said he is reviewing studies on curfews in France, Germany and Saudi Arabia. He later cited Portugal as another potential example.The decision on how to craft a curfew policy will be based on data from those studies, he said.In all four countries, restrictions have changed over time and it is not clear which iterations California is reviewing. The California Department of Health declined to provide more information when contacted Tuesday.“If we have additional details, we'll let you know,” a spokesperson said via email.Under France’s old rules, restaurants and bars had to close from 9 pm to 6 am. In Germany, restaurants previously closed at 10 pm. However, many European countries announced more strict lockdown measures in October amid surging rates of transmission that include limits on movement and travel.“Where there are areas that are very high risk, do you close them off in some way to not allow the spread to the areas with lower risk? We’ve seen that across the world,” said San Diego State University epidemiologist Dr. Eyal Oren.Under France’s new month-long lockdown, police ticket people who do not carry written permission justifying their need to leave home for a valid reason. Valid reasons include going to work, buying groceries, getting medical help or taking a child to schoolFrench citizens are allowed outside to exercise for one hour a day.In most of Portugal, shops close at 10 pm, restaurants close at 10:30 pm and people have to be in their homes by 11 pm with limited exceptions.On Saturdays and Sundays, the restrictions take effect even earlier: people have to stay home starting at 1 pm. There are also police checkpoints limiting travel between cities.Restrictions in Saudi Arabia have eased as the country prepares to host the G20 summit, but from March until late June the kingdom imposed a series of curfews that significantly limited movement.At times, police enforced a so-called “24-hour nationwide curfew.” Under this policy, people were only allowed outside their homes from 6 am until 3 pm for essential purposes like getting medicine, food or supplies. Individuals who left home were required to stay within their specific neighborhood; they were prohibited from traveling to other parts of a city.“Areas can be cordoned off to restrict transmission and that can work,” Dr. Oren said. “The degree to which people want to have the government do that is a whole different kind of question.”Dr. Oren said studies have shown links between curfews and lower case rates, but he says compliance and enforcement of those policies can be challenging.Many European countries paired their restrictions with big financial assistance programs to make them more popular. In Saudi Arabia, the kingdom covered 60 percent of employee salaries in the private sector and made healthcare free for everyone in the country.If the upcoming restrictions in Los Angeles County are any indicator, California’s statewide curfew could be very similar to restrictions already in place in San Diego County. But Dr. Oren said there would still be one significant difference: messaging.“I do think some of the words we’ve been using have become kind of stale,” he said, referring to phrases like stay-at-home orders.Simply labeling a policy as a “curfew” might help change the public’s perception of the dangers of the pandemic, he said. 4319

SAN DIEGO (KGTV) — As the world waits for a vaccine against the coronavirus, two San Diego biotechs are teaming up to develop a nasal spray using designer antibodies cloned from COVID-19 survivors.About 70 companies worldwide are working on therapies for COVID-19 using cloned antibodies, according to an estimate by the International AIDS Vaccine Initiative. A few of these treatments, known officially as monoclonal antibody therapies, have advanced to clinical trials.Most require an injection, but San Diego-based Diomics and its partner Active Motif, based in Carlsbad, are developing a once-a-day spray that could be easily self-administered.Early research suggests the coronavirus primarily enters the body through the nose. The spray, called Dioguard, is designed to coat the lining of the nasal cavity with cloned antibodies that are held in place for 24 hours or more using a proprietary polymer material developed by Diomics.Diomics CEO Anthony Zolezzi said he believes the spray “holds the key to allowing many aspects of life to resume until the day comes when there’s an effective vaccine in widespread use.”Diomics is also developing two tests for COVID-19 antibodies using its polymer beads, including a device that looks like a nicotine patch that is designed to monitor for infections for a week or more.RELATED: How a dot on your forearm could be the future sign of COVID immunityActive Motif is providing the cloned antibodies for the nasal spray. With a lab in Shanghai and other relationships in China, the Carlsbad company was able to clone antibodies from 11 Chinese survivors in February, before the World Health Organization declared a pandemic.When the company started the cloning project, they thought the virus would probably disappear in three to six months, said Active Motif CEO Ted DeFrank. “Then people started realizing, no this is going to be with us for a while.”The plasma from the 11 Chinese patients contained thousands of antibodies, and scientists with Active Motif set about selecting the one that was most effective, dubbed 414-1. The company says it can neutralize SARS-CoV-2 virus particles with 98 percent effectiveness.Monoclonal antibodies have some similarities to convalescent plasma, which is a complex cocktail of antibodies and other immune molecules drawn from the blood of recovered patients. One of the key differences is that cloned antibodies can be mass produced in a lab.Cloned antibodies have been used in treatments for more than 30 years, primarily for cancer. One such treatment famously helped former U.S. President Jimmy Carter beat melanoma.But of the more than 100 monoclonal antibody therapies licensed for use, only seven are for communicable diseases, according to IAVI.Historically, the treatments have been expensive and difficult to produce, but Diomics said it’s targeting a price of about a spray for Dioguard, roughly per bottle.“We do not want to have huge profits from a pandemic, that’s just wrong,” Zolezzi said. “We’re going to price this as effectively as we can for the masses. We want to get this out to the masses.”Animal testing is about to begin and the companies said they hope to progress to human trials soon. Their goal is to release the spray in early 2021, when a vaccine may be on the market but not yet widely available.If the spray works, it could be adapted to other viruses to help fight future pandemics, Zolezzi said."That’s our real goal," Zolezzi said. "That we never get caught flat-footed like this time." 3526
