The Silverado Fire continues to burn in the hills near Irvine as firefighters have been taking advantage of improved weather conditions to contain the blaze.

Evacuation orders in place for roughly 70,000 homes in Irvine were lifted this afternoon. Additional mandatory evacuations in much of Lake Forest were also lifted, although some homes in communitites adjacent to the Whiting Ranch Wilderness Park remain under mandatory or voluntary evacuation orders.

Here's what else we know so far today:

THE BASICS

• Acreage: 13,354
• Containment: 25%
• Structures threatened: At the height, as many as 69,058
• Structures destroyed: None
• Resources deployed: 1,200+ firefighters

On Monday, two firefighters were burned over at least half their bodies and were intubated. Orange County Fire Chief Brian Fennesy described them as "gravely injured."

Three other firefighters have sustained minor injuries.

The fire started at 6:47 a.m. Monday in the area of Santiago Canyon Road and Silverado Canyon Road, according to a post from the city of Irvine.

The strong, dry Santa Ana winds that howled through the region starting Monday let up Tuesday evening, and CalFire officials said crews were taking advantage of conditions by building containment lines overnight.

BACKGROUND

The area that's burning last burned in the Santiago Fire back in 2007.

That fire consumed 28,000 acres and destroyed 42 structures. Fuel is lighter this time around because of the previous fire, but there are far more homes threatened as developments have expanded.

CAUSE

Nothing is confirmed yet, but Southern California Edison has notified the state that its power line may have sparked the fire.

The report says "it appears that a lashing wire that was attached to an underbuilt telecommunication line may have contact SCE’s overhead primary conductor which may have resulted in the ignition of the fire."

An internal investigation at SCE is ongoing, according to the report.

EVACUATIONS

Note: Mandatory evacuations were lifted for the entire city of Irvine as of 2:50 p.m. Wednesday. Find details for Irvine zones via this map.

Lake Forest evacuation zones 1 through 9 have also been lifted, as well as Orange County zones MV1 and T3.

Several areas are still under mandatory evacuation, including Whiting Ranch Wilderness Park, parts of Foothill Ranch and Mojeska Canyon.
