MONTEREY COUNTY, Calif. -

UPDAE: 8/7/16 8:30 PM: Helicopters are in the air spraying water while hot shot crews are on the ground, trying to get ahold of the Soberanes fire.

"The fire last night did make an active run early this morning," said Don Jaques, Soberanes fire Public Information Officer.

Twenty mile per hour winds from the north are the reason for the run.

"That caused the fire to actually cross over some of our containment lines burning an area around 300 acres. That prompted an evacuation on a portion of the Big Sur area," said Jaques.

Tim Ames' neighborhood received a mandatory evacuation Sunday morning. Ames left, but it was only to get a radio signal.

"I live under the redwood trees and the radios don't work under the redwood trees, so I have to go out somewhere and listen to the radio," said Ames. “I can't see any reason to leave."

Fire officials said while they've been able to save thousands of homes and make a lot of progress, containing the fire is still difficult as it continues to burn in very steep terrain.

"This is a different ballgame than what we had at the earlier start of the fire,” said Jaques. “We had access to many roads and so forth."

To stop the fire from spreading any further, helicopters are dropping water into areas that are not safe for firefighters, and crews are trying to stay ahead of the inferno with controlled burns.

"We're working around the edges of the fire and making sure that it’s contained and not going to be able to get to those communities," said Jaques.

They're asking residents to keep updated on information and be ready to leave because the fire still has the potential to reach up to 163,000 acres.

"If I have to I can throw everything in my truck and leave -- if it gets within a few thousand feet, then I'll do that," said Ames.

An evacuation center is set up at All Saints Day School in on Carmel Valley Road. The American Red Cross said Sunday morning they had about 67 people come through. 

UPDATE: 8/7/16 4:30 PM: Here is the reason Cal Fire gave for the sudden evacuation of Big Sur this morning:

20 mile an hour winds from the north caused the fire to cross over some containment lines burning an area of around 300 acres. This prompted an evacuation from Coast road to Graves road. The fire is burning deep within the Ventana Wilderness area, which is very steep and rugged and difficult for firefighters to access. Now, hot shot and aerial crews are being used to fight that portion of the Soberanes Fire.

UPDATE 8/7/16 2:20PM: Evacuation orders have been lifted for all areas of the Big Sur community except for the following:

All residents living east of Hwy 1 starting at Coast Rd near Bixby Creek, south to the intersection of Andrew Molera State Park continuing on both sides of the highway towards Graves Canyon.

An evacuation is under way in Big Sur as flames from the Soberanes wildfire spread.

Monterey County Sheriff Steve Bernal confirmed with KION that his department issued mandatory evacuations early this morning in Big Sur.

Many residents of Big Sur received reverse 911 calls this morning.

Deputies have been visiting homes and businesses in the area to tell people about the order, according to the department's Facebook page.

The evacuation order is for the Big Sur Area from the Point Sur Lighthouse to Graves Canyon. 

Flames are reported to be on the other side of the ridgeline shown in the picture of Mount Manuel. Most of the businesses and homes are to the left of the photo.

The evacuation center is the All Saints Day School at 8060 Carmel Valley Road. 

As of Sunday morning, the Soberanes Fire is nearly 89 square miles and 45% contained.
