A brush fire that sparked alongside a highway interchange that took off in extreme fire conditions Thursday, scorching thousands of acres in Fallbrook and Bonsall is heading toward the more populated community of Oceanside and Camp Pendleton.

The Lilac Fire, as it's been named by Cal Fire officials, is burning out of control and has burned 4,100 acres since it sparked just after 11 a.m. Officials say 5,000 structures are threatened.

Flames marched through parts of Fallbrook and Bonsall, burning homes and ranch properties to the ground.

A mobile home park in Bonsall was devastated by the Lilac Fire as it broke out and quickly spread west Thursday. NBC 7’s Dave Summers reports from the Rancho Monserate County Club.

New mandatory evacuations have been issued as the fire moved west toward the cities of Oceanside and Camp Pendleton.



"Tonight is one of those nights, today is one of these fires," said Cal Fire Division Chief Nick Schuler. "This fire could make it all the way to Oceanside to the coast if it continues."

As of 9:20 p.m., new mandatory evacuation orders have been issued for:

Northerly winds pushed embers to the area north of SR-76 at Olive Hill Road. Helicopters were making night water drops and a bulldozer was working to cut a fire break.

As of 7 p.m., winds were 20 to 25 mph with gusts up to 35 to 40 mph.

"They're blowing in all kinds of directions," said NBC 7 weather anchor Llarisa Abreu.

Two civilians suffered burns in the fire and were transported to area hospitals to be treated, Cal Fire officials said. It was unclear how the injuries occurred.

A San Diego County Sheriff's Department deputy suffered minor injuries while directing traffic. At the time of the incident, visibility in the area was low due to thick clouds of smoke. It was not clear if it was a factor in the injury.

Twenty structures were destroyed and 12 structures were damaged by a fire that officials said was spreading at a dangerous rate. However, the total number of structures lost could be much greater.

In the Rancho Monserate Mobile Home Park, at least 40 units were destroyed, according to an NBC 7 news crew. Several more homes were damaged.

One Bonsall resident said it was like nothing he had ever seen before.

"It looked very eerie, very dark and overcast. It's almost like driving into Hell," Jerry Vasquez, who lives off West Lilac Road said.

Vasquez said he could see three or four homes burning as he evacuated.

Horses could be seen running in circles as firefighters opened homes' gates to free them.

Hundreds of horses were loose south of State Route 76 on Camino Del Rey, CHP officers confirmed.



As the Lilac Fire grew off SR-76 and I-I-15, horses on one property fled the flames. The troubling moments were caught live on NBC 7.

California Gov. Jerry Brown declared a state of emergency for San Diego County Thursday, freeing up federal resources as crews battle the fast-moving blaze. The county had declared a state of emergency earlier in the day.
