In California, where nine large fires are currently active, Gov. Gavin Newsom on Friday declared a state of emergency in four northern California counties due to the hasty spread of flames.
Butte and Lassen counties are under states of emergency prompted by the state's largest fire, the Dixie Fire, the governor said in a news release. The Dixie and Fly fires have pushed officials to put Plumas County under the emergency declaration as well as Alpine County due to the Tamarack Fire.
The Tamarack Fire also prompted Nevada Gov. Steve Sisolak to put Douglas County under an emergency declaration Friday.
"Now, more than ever we must stand united and use all our available resources to combat this growing threat in order to help our fellow Nevadans receive the aid they need," Sisolak said in a news release.
A state of emergency allows officials to access more funds and resources.
