It hit 114 F (45.5 C) here in the San Diego East County today, and may even be a little hotter tomorrow. Alpine, the town just north of the Valley fire in the linked video, hit its highest reading ever of 113 F.
So of course, somehow a wild fire started.

Here's the latest time lapse from 6-9 PM as it moves west (towards me).

It's still under 2,000 acres, so is dwarfed by the mega fires in the rest of California, such as those mmikeinsantarosa has had to deal with the past few years, but we had been spared up to now down here. There are some misinformed people (to be charitable) that have said that California needs to "clean" its forests to prevent the fires somehow, but you can see that these hills have already been clean of forests since the end of the last Ice Age, and we still get the fires.
