Critical fire weather is expected to continue until Wednesday at the earliest, increasing the risk that fires will spread further.

LA County Sheriff says about 31,000 people were under mandatory evacuation orders while another 23,000 were under evacuation warnings.

California Gov. Gavin Newsom on Sunday announced that he would deploy additional resources ahead of the extreme fire weather expected this week.

Gov. Gavin Newsom called for an independent investigation into the loss of water pressure to local fire hydrants and the reported unavailability of water supplies from the Santa Ynez Reservoir.

Two people were arrested for arson in separate incidents just outside the fire zone on Wednesday, according to the LAPD. In one incident, a citizen extinguished a fire in a tree and detained an arson suspect, police said. That suspect admitted to starting the fire because he "liked the smell of burning leaves," police said.
