Thanks for your concern!
I'm 400 miles north so no worries here. Up here we have had forest fires (in merchantable timber, up in the mountains) but I think our fire season is just average.
You are right about the lack of rain. The Los Angeles region is a desert, normally under 15 inches of rain annually and it doesn't rain from early May until a few showers about now. But this was the driest year in history, 3.21 inches total for the year July 2006-June 2007.

That whole region is dry desert like you see in cowboy movies, and some of it is steep. Nothing stops the fires when they are pushed by the hot Santa Ana wind that blows in from the southwest desert, farther inland. The 'Santa Ana' is feared, when it starts it always means trouble.
Many residential neighborhoods are built right next to the National Forests, which down there means steep dry desert sagebrush that nobody ever tried to farm or even graze. Then the fire comes up out of the canyon or down from the ridge and there is no way to defend the houses. The Santa Ana's were blowing over 100 mph, 160kph, so the fire front kept leaping ahead. I saw a report where a 10 lane freeway was not a sufficient firebreak, the fire was blown across and started up the other side.
Today they are hopeful for declining winds. One report I read yesterday said a commander had 100 planes but couldn't fly them because the wind was too rough.
Its a mess. I've seen reports of a half million homes ordered evacuated, and a half million people ordered out in just San Diego County. (which isn't as large as Los Angeles County.) This is dozens of unrelated fires all at once.
Our Northern California firefighters are down there, Mexican forces from Tijuana were offered and accepted immediately, and many fire commanders still don't have the resources to cover their communities.

The lead story is a good summary and several following stories are interesting.
