Fire crews made substantial progress over the weekend in battling the SCU Lightning Complex Fire across California’s East and South Bay regions, bringing it to the milestone containment point of 60 percent. The fire has charred 383,157 acres as of Monday morning; it remains the second-largest wildfire in state history.

Cal Fire reports the fight against the blaze is still unfinished and likely to get a little bit tougher with a less favorable forecast this week. With poor overnight humidity and anticipated high temperatures and dry weather, particularly on the western side of the fire, crews will work to seek safe access points in which they may pursue fire-controlling mitigation techniques.

The fire has destroyed 40 structures and 64 minor structures, and has damaged 18 more. Three first responders have been injured, as well as two civilians. There have been no casualties reported.
