Fire weather arrived in San Diego this weekend, traveling southward from Butte County via Ventura and Los Angeles. Its journey here gave us snapshots of a grim new reality: the unbelievable speed and scale of California wildfires. A line of burned-out cars in the Sierra foothill town of Paradise, and social media accounts of desperate attempts to outrun the Camp Fire. Four one-way lanes on the Pacific Coast Highway during a mass evacuation of Malibu to escape the Woolsey Fire.
