More wildfires ignited near Los Angeles on Thursday, destroying homes and forcing evacuations, as the region faced a second day of gusting desert winds that have fanned flames and displaced thousands of people. The fast-moving Hillside Fire grew to 200 acres (80 hectares) and was starting to consume homes near scrub-covered slopes in San Bernadino, east of Los Angeles, according to the San Bernadino County Fire Department. At least six homes were destroyed or damaged and about 1,300 people had been ordered to evacuate. A helicopter and a small plane dropped water and retardant on the flames, according to Chris Prater, a fire department spokesman. A smaller brush fire was also reported in Jurupa Valley. "The winds have probably been the biggest factor promoting this fire spread," he said. The region's Santa Ana winds have been so extraordinarily dry, powerful and prolonged that the National Weather Service created a new alert level, issuing an "extreme red flag warning" through Thursday evening in Los Angeles and Ventura counties. Two other major fires have charred the region since the start of the week. The Getty Fire broke out near the Getty Center art museum in Los Angeles on Monday morning, burning chaparral up and down the mountain slopes around a major highway. Officials ordered the evacuation of more than 10,000 homes in some of the city's richest neighborhoods, although they began allowing some people to return on Wednesday as about 40% of the 745-acre (300-hectare) fire was brought under control. The Easy Fire ignited early on Wednesday, sending flames racing up to the walls of the Ronald Reagan Presidential Library atop a mountain in Ventura County's Simi Valley northwest of Los Angeles. Some 30,000 residents were ordered to evacuate, along with an unknown number of horses in an area that is known for its ranches. County schools remained closed on Thursday. Officials at the Getty Center and the Reagan Library were confident both complexes would be unscathed, thanks to various fire-prevention systems. These include, in the case of the Reagan Library, an annual visit by a herd of goats that eats away the surrounding flammable scrub. On Wednesday, helicopters doused the area around the library with water. No injuries have been reported in the fires, although at least a dozen homes in Los Angeles have burned down. The Santa Ana winds arrive in the autumn, sending hot, dry air down from the mountains out to the Southern California coast. Gusts of 65 miles per hour (105 km per hour) were recorded in mountainous areas around Los Angeles, and more powerful winds were forecast for Thursday morning. Tens of thousands of people in the region were without power after a precautionary shutdown by the Pacific Gas & Electric Co . Investigators say the Getty fire was likely caused by a broken tree branch that was blown into power lines during high winds on Monday morning. In northern California, firefighters have been fighting the 76,000-acre (30,760-hectare) Kincade Fire in Sonoma County's wine country for more than a week. That blaze has destroyed at least 189 homes and other structures but was listed as 30 percent contained on Wednesday. PG&E acknowledged last week that the Kincade Fire started near a damaged transmission tower at about the time a live high-voltage line on that tower malfunctioned. The company filed for bankruptcy in January, citing $30 billion in potential liability from a series of deadly fires sparked by its equipment in 2017 and 2018. As many as 190,000 people were displaced at the height of the Kincade Fire, but some evacuation orders have since been lifted. —Reuters
