Strong and locally damaging wind gusts of 50 to 65 mph are expected to be most focused this afternoon into tonight across the Santa Barbara County interior mountains, Ventura County mountains, I-5 corridor, and Antelope Valley including the western foothills. These stronger winds combined with humidities lowering to between 10 and 25 percent will likely bring critical fire weather conditions to these areas, resulting in the Red Flag Warning valid this afternoon into tonight. While locally stronger winds are still expected to surface across portions of the eastern Santa Ynez range tonight, it no longer appears they will have a sufficient duration of strong wind/low humidity overlap, resulting in the cancellation of the Fire Weather Watch for this area, and just including them with brief critical headlines. Areas in a Red Flag Warning this afternoon through tonight will have the highest risk for rapid fire spread and extreme fire behavior, with the threat of long range spotting.
