More than 1,000 fires are burning over half a million acres of California countryside, and the flames have now claimed their first life - a 63-year-old volunteer firefighter in the north of the state.
Most of the fires are in sparsely populated areas.
Still, more than 8,000 homes are at risk and people in parts of three counties have been ordered to evacuate.
Members of California's National Guard have been drafted in to help.
John Scherrei, chief of the Santa Barbara Fire Department, says firefighters are hard pressed to cope.
"Could we use more resources? Absolutely. California is stretched thin," he told the Associated Press news agency.
"We have requests in for additional resources, and we don't know how long we can hold on to what we have."
