By Rachel Ramirez, CNN When Jessica Roberts heard that a fire ignited roughly four miles from where the Camp Fire started in 2018, she was catapulted back to the most traumatic experience of her life. The Dixie Fire is California’s largest active wildfire, having burned more than 240,000 acres of land — an area larger than New York City — over the course of two weeks. Its size jumped significantly last weekend when it merged with the Fly Fire in the Lassen and Plumas national forests. More than 7,800 residents across Butte and Plumas counties have been ordered to evacuate as of Monday morning.
