Firefighters are gaining steady ground on the Carr Fire, which has forced the evacuation of some 38,000 people and destroyed more than 1,000 homes.
Between July 26 and July 27, more than 20,000 residents of Redding were ordered to evacuate amid the rapidly-expanding Carr fire. Firefighters increased containment of those fires to nearly 40 percent. Fire crews from across the United States are being sent to California to help the firefighters there, many of whom are stretched to their limits as they battle 17 wildfires across the state.

Ninety-eight large active fires burned across the USA that week, according to the NOAA.
The state spent more than $114 million fighting fires in July, the first month of California's fiscal year.
Tens of thousands of people across California are waiting to return home or assess what remains of their homes after the fires.
Cal Fire said that "steep terrain, erratic winds, and previously unburned fuels are contributing to spot fire potential".
Though the prominence of inmate firefighters is relatively low in media terms, their presence on the front lines is not new; CalFire says inmate firefighters have been deployed in California since World War II when much of the state's manpower was focused on the war effort. They burned 14 homes and threatened 12,000 more.
Southeast of Redding, a blaze moved deeper into the Mendocino National Forest, "an area with some hunting cabins and some private property but no towns", Lake County Sheriff Lt. Corey Paulich said.
The fire burning for 11 days in and around the city of Redding is now 200 square miles (518 square kilometers).
Two fires in Mendocino County, the River Fire, which is 38 percent contained, and the Ranch Fire, 15 percent contained, have consumed almost 100,000 acres.
