Spotted at 10:35 am, there’s a serious plume of black, black smoke just outside my office window near the border of Northridge/Chatsworth. There’s already a ghetto bird police helicopter overhead.

Anyone know what happened?

Update: NBC Los Angeles is on the story.

Update 2: About 20 minutes after the plume first appeared, the fire seems to have been successfully extinguished. Go LAFD!
