Around 12,000 firefighters battled today to contain wildfires in California that have killed six -- but authorities warned "erratic" winds and dry conditions have caused the flames to grow and spread.
"Very hot and dry conditions will continue over the West coast states through Sunday. Conditions around the Carr wildfire near Redding, California will continue to be conducive to rapid wildfire growth and spread," the National Weather Service said this morning.
Firefighters in Shasta County, in northern California, where the Carr Fire began on July 23, warned on Twitter that "erratic winds and hot, dry conditions on the #CarrFire resulted in greater growth and increased fire behavior last night."
