The Silverado Fire continues to expand and as of Wednesday morning, it had burned 13,354 acres.

However, as the fire entered a third morning, crews were able to establish a larger containment area around the blaze.

In a tweet, Cal Fire announced the Silverado Fire is now at 25 percent containment, meaning that fire crews have worked to establish a map around the fire.

In an interview with Irvine Weekly, Orange County Fire Authority Captain Steve Concialdi explained how hand crews work in tandem with air support to create a parameter — or containment area — around that fire. This area is what is known as the containment area.

“The hand crew firefighters cut a line around the fire parameter, down to mineral soil, so that way it doesn’t grow, and the fire will stop at that point. That’s assisted by firefighters with engine companies with hose lines that will put water on the fire and vegetation and then our helicopters are dropping water on any hot spots, so that you can extinguish the fire,” Concialdi explained

In a Tweet Wednesday, the Irvine Police Department announced that there were no immediate changes to evacuations in place.

On Tuesday afternoon, the city of Irvine lifted some areas under mandatory evacuations. Those areas included south of Partola Parkway and west of 133 Toll Road, East of the 133 Toll Road to Portola High School, and everything north of Great Park Boulevard to Irvine Boulevard.

However, Irvine Boulevard remained closed between Axis and Alton.
