Meanwhile, in central California, where the Ferguson Fire near Yosemite National Park has grown to 54,481 acres with 30 percent containment, a second firefighter has reportedly been killed. Brian Hughes was struck by a tree while removing brush in an effort to contain the fire, according to officials.On Saturday, President Trump issued a federal emergency declaration for California.In the city of Redding, which has been at the forefront of the Carr Fire, officials sounded more hopeful for the first time in days as the strong winds of the last several days abated."We're feeling a lot more optimistic today as we're starting to gain some ground rather than being in a defensive mode on this fire all the time," said Bret Gouvea, the California Department of Forestry and Fire Protection's incident commander on the blaze around Redding, which is located about 230 miles north of San Francisco.Despite the improved mood, a sixth person was killed in the fire, according to Shasta County Sheriff Tom Bosenko.The Sacramento Bee reports that the Carr Fire "began surging into Trinity County, where the tiny community of Lewiston, with a population of about 1,100, was evacuated late Saturday."The newspaper reports:
