There are new evacuation orders that went into effect at 6 p.m. Saturday, according to Matt Corelli, of the U.S. Forest Service.

“The order includes the community of Lake Hughes, that's a mandatory evacuation for the community of Lake Hughes,” Corelli said. “The voluntary evacuation of the community of Lake Elizabeth.”
More than 2,000 residents are expected to be affected by the evacuations, he said.
"From 3 p.m. until (6:30 p.m.), we've had a real active fire," Corelli said. "I can't even say a number right now because it's too smoky and we can't even see the perimeter from the air."
The fire has burned more than 5,500 acres as of 3 p.m., according to Corelli, but a more accurate count has become impossible due to the smoke.
“Now where those evacuations take place is critical, as well, because it’s south of Lake Elizabeth Road so residents that live in both of those communities north of the road are not under evacuation, it’s simply south of Lake Elizabeth road, the communities of Lake Hughes and Lake Elizabeth and it is mandatory for Lake Hughes and voluntary for Lake Elizabeth.
“There also is a little, about a mile, maybe even a little less, that was not under evacuation, that is now under evacuation, thats from the Camp Mendenhall, down near Lake Hughes, all the way to Lake Elizabeth.
“So essentially the evacuation goes from Lake Hughes (Road) to Lake Elizabeth all the way to San Francisquito Canyon Road, and that is south of Lake Elizabeth Road, that is roughly 2,000 residents that will be affected by that."
The brush fire is still burning northeast, away from the Santa Clarita Valley and out toward Lancaster.
A more accurate percentage of containment is difficult because smoke has been obscuring the view for aerial helicopters, which is how firefighters track the blaze.
"We'll have a real accurate measurement by about 6 a.m. (Sunday) morning," Corelli said.
It went in a westerly or southwesterly direction earlier Saturday afternoon, and then it started to shift back toward the Antelope Valley around 4 p.m.
"The wind has shifted from the southwest," Corelli said. "And now, it's moving out of the southwest and it's pushing the fire to the north."
