The second major fire began Tuesday morning in Los Angeles County and quickly enveloped more than 4,000 acres.
The blaze comes amid a red flag warning - due to low humidity and fierce Santa Ana winds - that is expected to last through much of the week.
The crews were assigned to structure protection for both residential and business structures and could be in Los Angeles County for up to 14-days before returning home. The fire is now estimated at 50,500 acres and is being pushed by strong east winds. About 700 firefighters responded to what was labeled the Creek Fire.
On Tuesday evening, a fire official said he suspects hundreds more homes have been destroyed.
The Associated Press reports a new blaze erupted near Los Angeles in the Ventura, Calif., area early Wednesday. Mandatory evacuation orders were issued for an area of Bel Air bounded to the north by Mulholland Drive, to the south by Sunset Boulevard, the 405 Freeway to the west and Roscomare Road to the East, according to the Los Angeles Fire Department. Firefighters were battling on the scene, being supported by water-dropping helicopters.
It has been reported that Rupert Murdoch's Bel Air estate is in the line of fire. The blaze prompted the evacuations of 27,000 people and was zero percent contained Wednesday morning. That blaze destroyed about 500 homes and led to various policy changes, including a prohibition on wood-shingle roofs and the strict requirement to remove brush from around properties.
Clouds of black smoke were seen from miles away before blowing by wind over the valley. Terrazas urged people to monitor news broadcasts and social media, including www.LAFD.org.
A temporary evacuation center was set up at Hansen Dam.
"Driving to LAX just as they're closing the 405 for this roaring hillside fire near the Getty exit", Rebecca Keegan, the Vanity Fair correspondent tweeted Wednesday. The 101 remains open, but authorities warned drivers to be cautious traveling through the area.
