A ferocious wildfire in Southern California's rugged San Gabriel Mountains has exploded to cover 49 square miles — an area larger than the entire city of San Francisco.
With 1,300 firefighters battling the 3-day-old blaze, authorities reported devastating damage and warned more than 80,000 people to evacuate from 34,000 residences, according to The Associated Press.
The fire erupted Tuesday morning in Cajon Pass, and by Wednesday it had scorched more than 40 square miles, about twice the size of Manhattan. By Thursday morning, the monstrous blaze had spread another 9 square miles of land that's been parched by years of drought.
