The National Weather Service issued a warning that new fires could break out due to strong winds and dry conditions.
The service also extended the fire warning for the area after wind speeds reached dangerous levels.
In an effort to prevent the spread of the fires, authorities cut electricity to over 77,000 homes in the region.
Meteorologists have warned that the weather conditions in the area could lead to fire whirlwinds.
These rare fire whirlwinds, which can reach heights of 10 to 50 meters, intensify the fires and cause them to spread more rapidly.
The wildfires, which started in the early hours of January 7 and quickly spread due to strong winds, have already burned more than 37,000 acres.
