GRAND JUNCTION, Colo. — Crews battling the sprawling Pine Gulch Fire were presented with another problem overnight Tuesday — a flurry of lightning, and not solely from a rain-producing thunderstorm.Instead, it was the fire itself — now an estimated 125,000 acres after growing 37,000 acres overnight — that produced cloud-to-ground lightning for several hours early Wednesday.The phenomenon was a product of pyrocumulus clouds, which can form when moisture or atmospheric instability moves over an intense heat source, according to the National Weather Service.In the case of the Pine Gulch Fire on Tuesday night, an outflow boundary had produced showers near the Wyoming border, north of the fire area. When that moisture moved south, the fire responded with a rapid output of heat, leading to the pyrocumulus, according to the NWS forecast discussion Wednesday morning.Radar showed consistent lightning strikes for several hours, and NWS employees could see the lightning from their office in Grand Junction.The extreme nature of the Pine Gulch Fire produced a couple more byproducts, noticeable in Grand Junction overnight. When the smoke plume from the fire rebuilt, the temperature in Grand Junction rose from 78 to 90 degrees, according to the NWS forecast discussion. The plume was also dispersing ash, which was falling in Grand Junction.Lightning has been a steady concern for crews battling the fires. While some thunderstorms were in the forecast this week, they were likely to be dry, with not much rainfall and more lightning, increasing the fire risk.The Pine Gulch Fire is one of four major fires currently burning in Colorado that have already scorched more than 175,000 acres of land. The Grizzly Creek Fire burning in Glenwood Canyon was at 29,000 acres Wednesday and has Interstate 70 still shut down. The Cameron Peak Fire in western Larimer County was 15,738 acres as of Wednesday morning, and the Williams Fork Fire burning in Grand County was 6,726 acres.This story was originally published by Ryan Osborne on KMGH in Denver. 2056

GUERNEVILLE, Calif. (AP) — Two communities in Northern California's wine country were accessible only by boat Wednesday after a rain-swollen river overflowed its banks following a relentless downpour across an already waterlogged region.The small city of Guerneville north of San Francisco "is officially an island," with the overflowing Russian River forecast to hit its highest level in about 25 years, the Sonoma County Sheriff's Office said in a statement."Nobody is coming or going from the Guerneville area at this time," said sheriff's Sgt. Spencer Crum. The nearby town of Monte Rio was also isolated by floodwaters and all roads leading to it were swamped.The still rising Russian River was engorged by days of rain from western U.S. storms that have also dumped heavy snow in the Sierra Nevada, throughout the Pacific Northwest and into Montana, where Gov. Steve Bullock signed an emergency order to help keep up the supply of heating fuel amid frigid temperatures.Snow from the storms closed roads and schools and toppled trucks and trees from Oregon to Montana and an avalanche in the Sierra prompted Amtrak to suspend rail service between Sacramento and Reno, Nevada.The Russian River topped 42 feet (13 meters) Wednesday afternoon, when television helicopter footage showed homes underwater and cars submerged. It could crest at more than 46 feet (14 meters) by Wednesday night, officials said. About 4,000 residents in two dozen river communities were ordered to evacuate Tuesday evening but officials estimate only about half heeded the orders, Crum said.Jeff Bridges, co-owner of the R3 Hotel in Guerneville, said he and others who stayed behind were well prepared to ride out the storm. He and employees spent most of the night moving computers, business records and furniture to second-floor room. Reached by telephone, Bridges said there was about 7 feet (2 meters) of water at his two-story home in Guerneville Wednesday but was not worried."As long as everybody is safe, dry and warm, it's all fine. You just ride it out," said Bridges, noting that this flood was the fourth he's experienced in 33 years.He added: "People in Florida have hurricanes, people in Maine have blizzards; we have floods," he said. "It's the price we have to pay to live in paradise."Several areas in California set record-high rainfall totals, including nearby Santa Rosa, which had nearly 8 inches (20 centimeters) of rain in one day. The often-waterlogged Venado weather station 5 miles (8 kilometers) from Guerneville recorded more than 20 inches (50 centimeters) of rain in 48 hours.In the Sierra Nevada, which has already seen a month of heavy snow, two Amtrak trains together carrying nearly 300 passengers stopped and reversed directions because of an avalanche that closed railroad tracks. Service on Amtrak's California Zephyr between Reno and Sacramento, California, has been suspended until weather conditions improve, Amtrak spokeswoman Kimberly Woods said.California officials were also concerned about potential mudslides in saturated wine country hillsides and in areas scarred by wildfires in 2017.A mudslide Tuesday near Monte Rio trapped a man and a woman before they were rescued, messy but unharmed."I fell into the mud when the tree fell over the top of me. It happened so fast you don't even know," Kear Koch told KGO-TV.Elsewhere in the area, several people had to be rescued from cars stranded while motorists tried to drive through flooded roads. Nina Sheehan, who is visiting from North Carolina, had to abandon her rental SUV after it got stuck in a flooded hotel parking lot."We made a decision to take the rental car through the waist-high water and we got two thirds of the way and then the car stalled," she said. "Do not try to go through any water over a foot high because you never know what you're going to find."Firefighters in Monte Rio worked through the night pulling people out of cars stuck in flooded roadways and getting people out of their homes as water approached, Fire Chief Steve Baxman told the Press-Democrat newspaper of Santa Rosa."We took 17 people out of cars and houses during the night. Too many people are driving into water," he said.Other waterways, including the Napa River, also were expected to overflow their banks as an ocean-spanning plume of moisture continued tracking through the West.___Rodriguez reported from San Francisco. 4401

German Chancellor Angela Merkel has announced she will give up leadership of her center-right Christian Democrat Union party after 18 years in the post, German media has reported. Merkel announced during a meeting with officials that she will not seek to run for re-election at the party's convention in December. But she made clear that she wanted to remain as chancellor, a position she has held since 2005, RTL reported, citing party sources.The announcement is a sign of Merkel's weakened power within her own party, and waning popularity in the country.Both parties under Merkel's ruling coalition -- the CDU and the Social Democratic Party (SPD) -- suffered heavy losses in a regional election over the weekend.While the CDU remained the largest party in the election, which was held in the central state of Hesse, results were down 10% from the previous election.This weekend's election is the second blow to Markel's fragile "grand coalition" government. On October 14, the Christian Social Union, or CSU -- the Bavarian sister party to the CDU -- lost its majority in the Bavarian state parliament.The CSU has dominated politics in the state since the end of World War II, ruling for all but three years over the course of nearly seven decades.Speaking on October 15, Merkel admitted that voters had lost trust in the government and that it was her job to "make sure that trust is won back.""I will work on that with as much vigor as I can," she added.Bavaria bore the brunt of the 2015 refugee crisis; at its peak, thousands of asylum seekers were crossing into the state every day. Since then, both Merkel and her CSU allies have been criticized for their management of the influx. 1700

HAMPTON ROADS, Va. - As coronavirus continues to rage across the country, scientists are inching closer to developing a COVID-19 vaccine.Dr. Doug Mitchell used to be a pediatric infectious diseases specialist at CHKD and EVMS. He is currently the medical director of CHKD Medical Group and a pediatrician at Norfolk Pediatrics.“If we’re able to stick to the science in developing the vaccine, then that would be comforting if we could stick to the science and develop an effective and safe vaccine,” said Mitchell.Mitchell said the speed at which researchers are developing a vaccine to combat COVID-19 is nothing short of a miracle, but sticking to the clinical science behind the advancement is key for an effective and safe vaccine - and that takes time.“The stated goal that I saw by the CDC and/or FDA of wanting a vaccine that shows at least 50% protection and six months of safety data, that takes time,” he said. “We need a chance to show the safety profile of any new vaccine under the parameters of following the best science that we could follow.”Mitchell understands the process involved in developing a vaccine.More than 20 years ago, he was an investigator in several pediatric clinical trials. Many of the vaccines that came out of his lab are still used in children today.While there are still growing concerns about vaccines, the benefits outweigh the risks.“The flu vaccine clearly saves lives, clearly prevents illnesses, but it’s not 100% protective either, but we know it does have benefits,” Mitchell said. “The advantage there is the flu vaccine has been out for decades and we know its safety profile.”Similar to the rapid speed of developing a COVID-19 vaccine, Mitchell said a vaccine for H1N1, better known as the swine flu, was quickly put on the market.“The difference is, we already had decades of history of flu vaccines and their safety, so all that happened was developing the same flu vaccine that was protective against a different strain,” he said. “That’s a different ballgame than starting a vaccine against a totally different virus.”While the research continues, the fight against COVID-19 is far from over.According to Mitchell, the spread of the virus decreases when you reach heard immunity where enough of the population is immune.This story was first reported by Antoinette DelBel at WTKR in Norfolk, Virginia. 2363
