California was lashed by powerful winds Wednesday that fed one fast-moving wildfire near multimillion-dollar properties along the Pacific Coast Highway in Malibu while hundreds of residents fled another fire farther north as forecasters warned of the potential for “extreme and life-threatening” blazes.

Some 10,000 people remain under evacuation orders as the fire continues to threaten about 3,500 structures around Camarillo in Ventura County.
