This week, experts are sending warnings to those considering seeing people outside their household without quarantining first. One aerosol expert weighs in on just how dangerous the holiday could be."My simplest advice is it is not a good idea to meet with people outside of your household for a holiday meal. That’s the most important message that can be underscored, and the reason for that is there are multiple ways this virus can be transferred,” said Alex Huffman, an aerosol expert and associate professor at the University of Denver. “The closer you are increases the chances of that, but aerosols can come out of your mouth and mix into the room. The longer you're in that room, the more chance you have of getting sick.”Huffman says time, ventilation and proximity have a big impact on whether coronavirus droplets can spread and infect others."When you breathe and talk, the louder you talk, droplets and aerosols come out of your mouth. So, traditionally, droplets are on the bigger side, aerosols are on the smaller side," said Huffman.With no mask on, these droplets can land on the faces of people around you or on their plates."And so, the biggest danger with the Thanksgiving meal or holiday meal or any meal specifically, restaurants included, are that you have to take off your mask to eat and that is why eating together indoors is so dangerous," said Huffman.Huffman demonstrated how fast droplets can spread in the air by showing how quickly food coloring can spread in water. He also analyzed the risks of eating a Thanksgiving meal in person, taking commonly-used models and applying varying factors that come into play when eating with people outside of your household."And then, I used the same model to say, ‘What happens if we meet for holiday meals?’ Let's say we have 10 people. We all eat for two hours. We all don't have masks on, and then, we ran different scenarios. If it was a small room, a large room, a medium-sized room and then estimate the amount of risk that would be from aerosol," said Huffman.Matching with community transmission rates, Huffman estimated that the probability of each person at the table having COVID-19 was about 5 percent."If it's a small room, everybody has something like a 15 percent chance of getting infected, even if we had no idea if anybody was infected or not. If it's a big room, it's a little bit less than that," explained Huffman.Ventilation also comes into play, which is why experts are advising that if you really are planning to meet with family this holiday, do it outside. Opening windows and doors also helps. Huffman also has some tools people can use, such as a carbon dioxide monitor or you can create your own box fan air filter."On the back, this is a furnace filter that’s also 20 inches and so you tape them together so they're well-sealed. You turn it on high and you blow the air through this filter and that removes the particles in the room that could potentially contain virus in it," said Huffman.Still, Huffman and other medical experts agree this won't completely eliminate the risk of spreading COVID-19. The safest thing to do is stay home and avoid celebrating Thanksgiving with people who are not part of your household. 3230

TRABUCO CANYON, Calif. (KGTV) – A large brush fire burning in the Cleveland National Forest’s Trabuco Canyon is spreading quickly Monday afternoon. The fire, dubbed the Holy Fire, was reported around 1:30 p.m. near Holy Jim Canyon and Trabuco Creek roads, according to KABC.The Orange County Fire Authority said the blaze grew quickly from between seven and 10 acres to at least 4,000 by 8 p.m. and is currently spreading at a moderate rate. The Holy Fire is zero percent contained.  511

Thousands of Central American migrants fleeing poverty and violence packed a bridge connecting Guatemala and Mexico in sweltering heat Saturday as part of a politically charged, U.S.-bound caravan.At one point, several dozen migrants trying to make their way north sang the Honduran national anthem on the edge of the muddy Suchiate River between Tecun Uman, Guatemala, and Tapachula, Mexico.Their journey continued one day after defiant caravan members rushed passed border gates only to be stopped by rows of Mexican riot police who dispersed tear gas and smoke canisters into the crowds.The slow procession north has led President Donald Trump to threaten to cut aid to Central American nations and to send troops to the U.S. border if Mexico failed to stop the surge."Our message is we're not criminals," Honduran migrant Orlean Herrera said. "We're coming over here because we need a better life. That's why we're here." 933

There was a rare sight at San Diego City Hall on Tuesday.A local developer pitched a massive mixed-use complex with hundreds of homes to the council, in front of mostly empty seats. "Our focus has always been on creating a sense of place for the entire neighborhood," said builder Gary Levitt, of Sea Breeze Properties.Sea Breeze Properties plans to transform a 72-acre site just south of the 56 into hundreds of homes, plus offices, retail, and even a hotel and movie theater. The project, Merge 56, didn't get a single 'no' vote from multiple community planning groups.Some nearby residents even came to the meeting to support the project. But even with that backing, it still took five years just to get the council's unanimous vote of approval Tuesday.Levitt said the delays come from regulations, including environmental impact reports, and cost his company an extra million - about 15 percent of that in city processing fees.Councilman Scott Sherman said that is one reason we're in housing crisis. "At the end of the day all the prices get passed along to the consumer and the price of housing," Sherman said. Levitt said ideally it would take two years for a project to get approved. "It's a very expensive process and at the end of the day you're just playing with paper," he said. The project includes 242 new homes, condos, and apartments. Additionally, 47 of them will be affordable units. Two environmentalists did raise concerns about local impacts but the council didn't acknowledge them in their deliberation. Levitt's work, however, isn't done. He still has a number of permits to obtain. They're administrative, but he estimates it'll be about four months before he breaks ground.   1771

"Forest health experts help identify areas where Christmas trees can be cut, opening up forage for wildlife and allowing the remaining trees to grow larger."According to the Forest Service, there are specific guidelines to follow, including having your permit on you at all times. You'll also need to contact the forest district office nearest you for cutting instructions.The permits will set you back between to , varying by location. 1173
