6. There is an old axiom in wildland fire fighting: "Wind changes everything."

Santa Ana winds put that axiom on steroids. Strong downslope desert winds undergo compression, which generates heat. So you get "double drying" .. drying from heat and drying from high velocity winds. Any little spark .. ANY LITTLE SPARK .. can start a catastrophic wildfire.

Some winds in the area of the Palisades fire have been clocked at almost 100 mph. You cannot fight fire in that kind of wind. You cannot fly helicopters in that kind of wind. You cannot fly tanker aircraft in that kind of wind.

Palisades has grown from 1200 acres to almost 3000 acres in the past 12 hours. And there are numerous other significant fire starts in the area (Woodley, Hurst, and Eaton fires) upwind of Palisades.

Another old saying in wildland fire fighting is "F.E.A.R." - fuck everything and run. There are over 25 evacuation orders (Level 3 - GO!) in the area of Palisades.

Wind changes everything. F.E.A.R.!
