More than 9,300 firefighters are now battling at least 21 wildfires, according to the California Department of Forestry and Fire Protection, or Cal Fire.
The largest inferno, the Rocky Fire, has already incinerated 54,000 ares in three counties. As of Sunday night, it was only 5% contained and was feeding on the state`s drought to grow, Cal Fire spokesman Daniel Berlant said.
"This has been a very fast-moving wildfire with the dry conditions, and the weather not really cooperating with us over the past week," Berlant told CNN affiliate KCRA.

Almost 2,000 fire personnel, 180 engines, four air tankers and 19 helicopters are battling that blaze.
Across the state, more than 134,000 acres have been torched by the ongoing fires, according to Cal Fire.
