They're saying the Santa Ana's aren't supposed to die down until Tuesday.
Unique, controlled burns in these areas would be incredibly difficult due to canyons, etc. There are numerous fire breaks/roads all over the place, though. I hiked many of them w/ family pups and my own, when I moved out on my own.
Also, the type of brush that grows is chapparal, which is a very oily bush. One is = to roughly 1 barrel of oil. These bushes grow wild all over S. Cal., so when it's dry, they're fuel for wildfires, especially when areas haven't burned in years.
That's why when you see footage of the fires, you'll see explosions, now and then. It's those bushes igniting.
Santa Ana's are stronger in the am, too. Around dawn and lessen during the day.
