The National Weather Service said what could be the strongest Santa Ana windstorm in more than a decade began Tuesday across Los Angeles and Ventura counties and was forecast to peak in the early hours of Wednesday, when gusts could reach 80 mph (129 kph).

Wind-fueled wildfires continued to grow Wednesday as overtaxed fire crews battled three major out-of-control blazes that killed at least five people and ravaged some of the most picturesque neighborhoods in the Los Angeles area.
