Since last week, tens of thousands have been forced to evacuate their homes as the Carr fire, the most aggressive of the blazes, rages on.
Six people have lost their lives in the blaze, which has consumed 95,000 acres of land and destroyed 657 homes.
The deceased include a firefighter, and a woman along with her two great-grandchildren.
On Monday, as many as 10,000 firefighters were called up to join the National Guard who have been mobilised.
Brian Rice, a Californian firefighter helping to tackle the fires, told the New York Times: “This job has gotten twice as buys and twice as violent.”
Gale force winds have eased and slowed down the spread of the fire, but temperatures are expected to top 38C later this week, according to the National Weather Service.
It follows an official update from the Californian fire department on Monday, which read: “Northern portions of the fire remained active throughout the day. Firefighters continued to construct containment lines and contingency lines.
“Winds will increase late tonight and into tomorrow morning. Hot and dry weather, previously unburned fuels, and steep terrain will contribute to fire growth.
“Crews will work to mitigate spot fire potential across control lines. Evacuation orders have been lifted for Douglas City, and portions of Happy Valley, Shasta Lake City, and Redding.”
A map has been released by the fire department, highlighting all the points where wildfires have broken out.
A caption on the official California safety website says: “Field damage inspection is still ongoing and subject to change. The points shown in this map are being updated regularly.
“Data is subject to change as information is gathered and verified.”
The Carr fire began in the Whiskeytown–Shasta–Trinity National Recreation area.
The blaze was originally reported at an intersection of the US highway 299, and Carr powerhouse road on July 23.
The official cause of the fire has been recorded as ‘Mechanical Failure of a Vehicle’.
The vehicle in question ignited the fire while California was undergoing the severe arid conditions and high temperatures that underline the state’s devastating wildfire season.
