Southern and central California have always received far less rainfall than northern California, Oregon, and Washington, because the cold ocean current off southern and central California produces relatively few clouds by evaporation to come ashore causing rain, so as the population densities in the rural areas of southern and central California increase, more downed power lines and cigarettes-butts-not-put-out and even tires bursting cause sparks or flames which often ignite the kindling, much of the kindling not cleared by the green-heads running the government of the state of California.
