Winds of up to 40mph (64km/h) are expected throughout Tuesday in the state's South, where the Woolsey Fire is threatening some 57,000 homes.

Firefighters in the North are still battling the Camp Fire, which has left at least 42 people dead.

Meanwhile, two new fires began in the South on Monday.

They started within minutes of each other. The smaller of the two has since been put out, news agency, Reuters reports.

In the North, the Camp Fire, which has destroyed almost 7,200 homes, surpassed the 1933 Griffith Park disaster to become the deadliest in California's history after 13 more bodies were found, bringing the total killed to 42. The earlier tragedy left 31 dead.

Many more people are said to be unaccounted for, with coroner-led search teams preparing to comb the largely incinerated town of Paradise on Tuesday.

Three portable morgue, as well as specialist dog units, forensic anthropologists and a "disaster mortuary" have been requested to help with the operation, Butte County Sheriff Kory Honea told reporters on Monday.

The Woolsey Fire has so far killed two people as it damaged beach resorts including Malibu, a favourite with the rich and famous.

More than 300,000 locals have been forced to flee their homes across California.

US President, Donald Trump, has declared a "major disaster" in the state, making federal aid available to affected residents.
