SAN DIEGO (KGTV) - Californians associate “The Big One” with a devastating earthquake, but U.S. Geological Survey experts say a potentially larger threat could hit the state in the form of an “ARkStorm.”SPECIAL REPORT: Complete coverage of California's winter stormsExperts from every scientific field related to a potentially disastrous weather event gathered in 2010 to create the ARkStorm Scenario report for the USGS, imagining aspects of flooding of biblical proportions reaching the Western United States.“These storms do pose a real risk to California, in some ways far greater than that of earthquakes,” experts said in the study.The ARkStorm Scenario report reads like a Hollywood post-apocalyptic film script. Weeks of rain and snow are followed by catastrophic floods, landslides, and property and infrastructure damage which would cripple California’s economy.While the name “ARk” brings to mind a lifeboat scenario, ARkStorm project manager Dale Cox and chief scientist Lucile Jones coined the abbreviation to represent “atmospheric river.” A common term for meteorologists, these rivers in the sky work like highways for water vapor which comes to a screeching halt when it reaches land.A typical atmospheric river is the Pineapple Express, which pushes moisture from the tropics to the West Coast. It was a Pineapple Express that reached San Diego on Valentine’s Day, bringing warmer rain and lower snow levels, according to National Weather Service meteorologist Alexander Tardy.RELATED: Mega storm could cause billions in damage to California, report showsModels in the ARkStorm report show multiple areas of submergence in central San Diego. Mission Beach, which routinely sees flooding during heavy rain, is underwater in the ARkStorm scenario. Fiesta Island, ordinarily dry, disappears under Mission Bay.West-facing beaches, including those near Highway 1 in North San Diego County, are covered in water. Imperial Beach fares no better in its known run-off spots.“You have this outflow then you have the storm pushing in; it dams up,” says Cox of the coastal flooding impact.RELATED: How to check if your neighborhood is at risk of floodingTiming is critical in the creation of an ARkStorm. The same amount of precipitation predicted in the ARkStorm Scenario fell in 2017, says Cox. What made the difference in the impact, he says, is that the rain fell in 80 days instead of the 23 days imagined in the report.The West Coast will get notice, but not much, Tardy says. The most reliable models could give Californians a three-week warning for heavy rain.“We’re going to see it coming, but not where we can build a new levee,” Tardy said.RELATED: How San Diego's flooding compares to FEMA's historical hazard mapThe timing of the next ARkStorm is uncertain.“It could be next year, or it could be 120 years from now,” said Tardy.San Diego has seen significant rainfall in the 2018-2019 season, but few storms in recent years can compare with the potential disaster envisioned in ARkStorm.RELATED: Photos: Flooding catches San Diego by surprise“How do we help people understand it can get bigger than what they remember,” Jones said. “We prepare for the ones that we remember.”To create the report, experts accessed information from the records of Spanish ships off the coast of San Francisco in the 1600s. Other data were collected from tree rings, and newspaper reports from Sacramento in 1861 and 1862, the years an epic storm submerged California’s Central Valley past the level of telephone poles.As severe as it may seem, the ARkStorm Scenario is not the worst case scenario, said Jones.“If it has happened, it can happen again. And it probably will happen again.” 3695

SAN DIEGO (KGTV) — California's regional stay-at-home orders will go into effect in San Diego County on Sunday after the Southern California region fell below the 15% ICU threshold that triggers the restrictions.The state Department of Public Health announced the Southern California region, which includes San Diego, Los Angeles, Orange, Riverside, Imperial, Inyo, Mono, San Bernardino, San Luis Obispo, Santa Barbara, and Ventura counties, fell to 13.1% ICU capacity on Friday. That number dropped to 12.5% on Saturday.The restrictions will begin for a region at 11:59 p.m. on Sunday, according to the state. The region will be allowed to exit the order and return to previous reopening restrictions on Dec. 28 if ICU capacity projections for the following month are above or equal to 15%.RELATED: San Diego hospitals react to Newsom’s regional stay-at-home orderUnder the regional stay-at-home order, restrictions will last for three weeks and ban gatherings of people from different households. Several businesses will also be forced to close, including:indoor and outdoor playgrounds;indoor recreational facilities;hair salons and barbershops;personal care services;museums, zoos, and aquariums;movie theaters;wineries, bars, breweries, and distilleries;family entertainment centers;cardrooms and satellite wagering;limited services;live audience sports; andamusement parks.Schools with a waiver, "critical infrastructure," retail stores at 20% capacity, and restaurants offering takeout and delivery service can stay open. Hotels can also remain open "for critical infrastructure support only," and churches would be limited to outdoor services. Businesses have 48 hours to comply with the new health order.RELATED: Gov. Newsom: New California stay-at-home order triggered by ICU capacityOn Friday, San Diego County reported a record 2,039 new cases of COVID-19, and seven additional deaths, bringing the local tally to 88,181 cases and 1,047 deaths. The county has 791 coronavirus-related hospitalizations, 216 of those in the ICU, according to Friday's data. San Diego County's ICU capacity sat at 23%. Over the last 30 days, county health officials said there has been a 178% increase in COVID-19 hospitalizations and a 121% increase in COVID-19 ICU cases.San Joaquin Valley also fell below the state's threshold on Friday, with 14.1% ICU capacity, according to CDPH:Bay Area: 21.2%Greater Sacramento Region: 21.4%Northern California: 20.9%San Joaquin Valley: 14.1%Southern California: 13.1%Multiple Bay Area counties have already started the latest health order.

SAN DIEGO (KGTV) - As President Donald Trump threatens to shutdown the U.S.-Mexico Border, San Diego leaders are in Mexico City to strengthen economic ties and talk binational business.Five mayors and nearly 100 elected officials, business and community leaders from San Diego and Baja California left for Mexico Sunday for the San Diego Regional Chamber of Commerce’s 14th annual Binational Delegation to Mexico City.San Diego Mayor Kevin Faulconer said the top two issues up for discussion are the continuing Mexican sewage runoff problems that impact our beaches and the free trade relationship between the U.S. and Mexico.Monday, Mexican officials said 70 percent of trade with the U.S. is by trucks, and the Mexican Government is ready to collaborate with the U.S. to ensure border safety and that trade flows efficiently.“Free trade is incredibly important to our region here in San Diego,” said Faulconer. "We have over 100,000 jobs that are dependent upon trade with Mexico.”Faulconer said the goal is to create a safe, secure and functioning border. He is also calling for the approval of the new United States-Mexico-Canada Agreement, or USMCA.The Chamber also said advancing USMCA is a key priority of this week's meeting.Monday the delegation will discuss the U.S. Mexico trade relationship, including the border, immigration and economic development. On Tuesday the delegation will discuss the U.S. Mexico water policy.Imperial Beach Mayor Serge Dedina has been pushing for the Mexican government to rebuild basic sewage infrastructure. The sewage runoff from the Tijuana River Valley flows into some of our local beaches, shutting them down for days and sometimes even months.Dedina said he hopes to come back to San Diego with new solutions to resolve the ongoing, decades-old issue.“Will be really pressing really hard with high-level officials to really move this forward so we can continue to have clean beaches,” he said Sunday.The leaders will wrap up their trip to Mexico on Wednesday. 2016

SAN DIEGO (KGTV) — As wildfires continue to burn in California, researchers say they may be adding fuel to another emergency: the pandemic.Parts of the Golden State have been buried in a blanket of smoke for weeks. Wildfire smoke is a mixture of many pollutants, but the majority consists of tiny particulate matter called PM2.5, which can also be produced by cars and power plants.“It’s a threat amplifier,” said Dr. Abisola Olulade of Sharp Rees-Stealy Medical Group.In April, researchers at Harvard found that just a small increase in this kind of air pollution led to an 8% jump in the death rate from COVID-19.Studies have shown that air pollution from these tiny particles can increase the risk of death in older adults from other causes, but the Harvard researchers found the increase from COVID-19 was 20 times larger.Why? The most widely accepted theory is that smoke particles, which can burrow deep inside the lungs and enter the bloodstream, can add a layer of health complications for people already fighting the virus.“People that are already fighting off a COVID-19 infection already have compromised heart and lung function if they have severe illness,” Dr. Olulade said. “So that can increase their susceptibility to the effects of wildfires.”The particles can contribute to more inflammation and potentially lead to blood clotting, she said.“Any chink in the armor, so to speak, is going to really make people have trouble maintaining” the body’s stressful fight against the virus, said Dr. Christian Ramers of Family Health Centers of San Diego.Another theory from early COVID-19 research that hasn’t been peer-reviewed: smoke particles could allow the virus to travel farther and survive longer, potentially allowing it to spread to more people. Both Dr. Ramers and Dr. Olulade said there was less research to support this theory.“What makes the sky look hazy when there’s smoke? It’s particles. So it's conceivable, again this is kind of conjecture, but it's conceivable with more particles in the air then yes the virus can latch onto those particles a bit more,” said Dr. Ramers.Doctors say there’s stronger evidence to suggest that wildfire smoke could help the virus enter a healthy person’s body. Not only does smoke wear down the protective lining of our airways, it stimulates certain receptors in the lungs -- the exact receptors that the spike proteins of the coronavirus use to get inside cells.“The virus binds to those ACE2 receptors, so if you have more of them, it can increase the viral load,” said Dr. Olulade.All kinds of air pollution put us at greater risk from respiratory diseases like coronavirus, not just wildfires. But one thing is for sure: Californians have been exposed to a lot of smoke lately.Since the beginning of the year, wildfires in California have burned more than 3 million acres, according to CAL Fire. That’s an area larger than the entire County of San Diego. 2929
