The remains of stores and homes smolder after the Dixie Fire ripped through downtown Greenville, California. Authorities had earlier issued alerts to residents still in Greenville and Chester, as winds of up to 35 mph fanned the flames of the Dixie Fire, the largest blaze in the state -- which has grown so big that it generates its own weather system. The Dixie Fire has been burning for three weeks and spread to over 428 square miles (1,108 square kilometers), devasting huge swathes of Butte and Plumas counties. IMAGES
