LOS ANGELES (AP) — The winds aren't changing for Southern California's wildfires yet. The fifth largest blaze in state history was threatening thousands of homes as it churned through coastal mountains amid persistently dangerous weather conditions. Red Flag warnings for fire danger due to Santa Ana winds and a critical lack of moisture were extended into the week instead of expiring Monday afternoon as was initially forecast. "It doesn't get much drier than this folks," the National Weather Service Service tweeted, adding that more than 80 observation sites in the region reported afternoon relative humidity levels between just 1 and 9 percent.
