Well, no, there aren’t. If you set foot in LA, you would know that none of the local ranges are forested. As far as sagebrush, it exists not just in the foothills, but also in open areas like river plains in the basin. Presumably you know that it’s flammable by design, but it doesn’t spread embers under normal circumstances. It’s no different than a grassfire, which is what we consider when weeds catch fire.
This fire didn’t spread because some dry native plants and weeds caught fire. They do that all the time and our infrastructure can easily douse those fires quickly. This fire spread because the region itself is abnormally dry because of La Niña and the highly unusual placement of the low over the Gulf of California created extremely high winds.
like I told you, not in anybody’s lifetime have we seen hurricane force winds at lower elevations and over wide expanses.
