Images: Tracking California's wildfires

Wildfires raging in Southern California over the last several days have destroyed hundreds of homes and forced thousands of people to evacuate, and the situation could get worse before it gets better. A dozen or more fires have burned more than 400 square miles in an area extending from Los Angeles to San Diego.

This satellite image from Monday afternoon, with smoke billowing out over the Pacific Ocean, gives an indication of the extent of the fires (outlined in red).
