VENTURA, Calif., Dec 8 (Reuters) - Growing wildfires chewing through parts of Southern California on Friday ravaged avocado farms, racehorse stables and a retirement community, even as milder weather aided firefighters in their efforts to slow the progress of six major blazes.

Forecasters predicted weather would continue to challenge the 8,700 firefighters who have been battling fast-moving blazes for five days from the San Diego area up the Pacific Coast to Santa Barbara County. The fires killed at least one person, destroyed 500 structures, hurt six people and injured four firefighters.

At the peak, about 212,000 people were forced to flee their homes. Evacuation orders were lifted in some areas, welcome news for many in shelters waiting to see if their homes survived.

"The weather moderated today and the milder winds allowed for an increase in the number of both helicopters and air tankers that could safely complete mission dropping water and fire retardant, as well as conducting reconnaissance tasks," the Ventura County Fire Department said on its website Friday evening.

U.S. President Donald Trump on Friday issued a federal emergency declaration for California, allowing the Federal Emergency Management Agency and Department of Homeland Security to coordinate relief efforts.

A 70-year-old woman died in a car crash on Wednesday with smoke inhalation and burns along an evacuation route in Santa Paula, the Ventura County Star newspaper reported, citing medical examiner Christopher Young.

Two of the most dangerous fires, in Ventura County and San Diego County, were zero to 10 percent contained, the CAL FIRE agency reported. Billions of dollars in property is at risk.

A joint weather forecast by firefighting agencies said temperatures would remain "well above normal for the foreseeable future." Winds were expected to continue, peaking in strength on Sunday then becoming much lighter on Monday. "Ongoing fires may see significant growth on Sunday," it said.

North of San Diego, the Lilac Fire swelled from 10 acres to 4,100 acres (1,659 hectares) in a few hours on Thursday, prompting Governor Jerry Brown to declare a state of emergency for San Diego County. The fire destroyed 65 structures.

Fallbrook, known for its avocado orchards, burned, and homes were destroyed in its Rancho Monserate Country Club retirement community. Blazes approached the Camp Pendleton marine base.

A 500-stall stable for thoroughbred race horses at San Luis Rey Downs training site burned late on Thursday, the Los Angeles Times reported.
