SAN DIEGO (KGTV) — Santa Ana winds have fueled the most destructive wildfires in San Diego’s history, including the Cedar Fire in 2003 and the Witch Creek Fire in 2007.But why do Santa Anas form and what makes them so effective at spreading fire?Typically, during the day, San Diego’s winds blow from the ocean to the shore. These onshore winds tend to carry a lot of water vapor.However, Santa Ana winds blow the opposite direction, from the east to the west, and they have all the ingredients fires need to spread.“Strong winds,” said National Weather Service San Diego meteorologist Philip Gonsalves. “They’re typically very dry, and we usually end up with warmer conditions.”Strong. Dry. Hot. A fourth key factor elevating the fire danger is the timing of this wind pattern.“They typically occur in the fall, which is that time of the year when the fuel moistures are very low, and so the fuels are primed for ignition,” Gonsalves said.Winds flow from areas of high pressure to areas of low pressure. Santa Anas form when there is high pressure over the Great Basin, located in Nevada and parts of Utah, and low pressure over Southern California.The winds are coming from the desert, but that’s not why they’re hot. They are hot for the same reason that air coming out of a bicycle pump is hot, Gonsalves said. It’s because the air is getting compressed.As the winds flow west out of the Great Basin, they travel over mountains. At high elevations, the air is very cool, but as the winds move downslope into lower elevations where the pressure is higher, the air gets compressed. That compression rapidly drives up the temperature in what’s called the Adiabatic Process.This process also dries out the air, and dry air can heat up much faster.As the winds move downslope, they pass over ridges and through canyons, which act like funnels, speeding up the winds.Santa Ana winds can pop up any time the Great Basin is cooler than Southern California, typically from September to May. But peak season is considered to be October.The Santa Ana event on Tuesday is falling a little before the peak season because of the positioning of highs and lows in the Northern Hemisphere, Gonsalves said, but the end result is the same: strong, dry, warm winds and extreme fire danger. 2281

SAN DIEGO (KGTV) - San Diego Pride is calling for video submissions that will be incorporated into their live-streamed event in July, in lieu of in-person gatherings. They are requesting people submit 15-30 second videos describing what Pride means to them. “We’ve learned as a movement and community that sharing personal stories is what pulls at hearts and minds and can help shape policy,” said Fernando Lopez, the Executive Director of SD Pride. But he also said he wants to make sure that even though the event will be virtual, it still creates a place for the LGBT community to express themselves. “What we’re doing is asking everyone to participate,” said Lopez. “One of the things that makes Pride special and unique is that we ask everyone from all walks of life to come together and celebrate diversity and to be together in community. We’re trying to do that but do it in a different way.” The videos will be incorporated into their live broadcast on July 18. As a year-round educational and advocacy organization, Lopez said SD Pride has already moved a lot of its events online. In doing so, he said they’ve actually been able to expand their reach. “When we’d have an educational forum, you’d get 40-80 people in a room,” he estimated. Now he says they are drawing thousands of people to their online forums.“We’re producing more programming than we have ever before and reaching more people than we ever have before,” said Lopez. To submit a video, go to this link on the SD Pride website. 1513

SAN DIEGO (KGTV) – San Diego’s tourism industry is preparing for a hit with restrictions and travel advisories in place ahead of the holidays.Since the onset of the coronavirus pandemic in March, research shows the San Diego region has lost .6 billion in tourist money.Last week, Gov. Gavin Newsom announced California, Oregon, and Washington were issuing a travel advisory, asking people to self-quarantine for 14 days if they’ve traveled out of the state or out of the country.The announcement coincides with the CDC urging Americans to stay home and not travel over the holidays.Local hotel owner Bob Rausch said he believes this won’t just hurt his business, but San Diego’s tourism in general. Rausch said tourism is an important part of the city’s economy.“Even if you don’t work directly in the industry, you likely are getting the benefits of tourism,” said Rausch. “I don’t see any good news for the next six months because it’s not our peak season, there are no corporate travelers coming because of all the restrictions. And there aren’t any groups allowed in the state. And leisure travelers are being told to stay home and that was our only business.”It's grim news for business owners who are trying to keep their doors open, and economists are predicting it will take five years for San Diego’s tourism to recover. 1339
