Because of the Santa Ana winds (with this apparently being more than usual), you'll continually have very dry conditions with high winds and the danger of a fire getting out of control. I don't see it as a black swan either. This is a repeatable scenario, every few years they'll probably have conditions like this. The climate is changing, maybe this will spread or move to areas nearby.

I live in an area that had a special warning last summer, we had a very very dry summer and there was a period with low humidity and high winds for a few days, it was considered an unusual scenario with extreme fire risk - but nothing happened this time. Now that I'm writing this I'm wondering what I'll do if it feels like an annual occurrence. Another parallel, the power company warned us they might shut off the power to reduce risk but I guess it didn't get that bad.
