Two very wet winters caused fuel buildup followed by an extremely hot and dry year.
References for the "hot and dry year" ('cause I hear it tossed around a lot). As far as I can tell, all of California had several relatively wet (but hot) years and nothing dry afterwards. I'm linking to NOAA's the California drought map, which shows "Abnormally Dry" (less than "moderate drought") for LA currently and I think showed "none" for much of the year [1].
The thing is, I agree this was to be expected. But only by the principle "climate change is going to cause disaster out of nowhere". We need to say this and let people understand.
This was also to be expected in the sense that forecasters for a week now have been warning about century long record wind speeds and the fire dangers those bring along with them
Sure but that's quite different from implications that the conditions of the past year pointed to this. I follow the Dought Monitor regularly and as a California resident, I want to know if rainfall patterns point to danger. I don't see indications here (see link in my parent post).
Wind speeds and live fuel moisture level are the critical measures of fire risk in chaparral. Fuel moisture levels have been approaching critical this season in Southern California and, due to lack of rain, didn't follow the seasonal pattern:

I looked at your first link. The 2024 curve is incomplete but roughly follows (but is above) the average of the 1980-present average curve. The 2023 curve similarly.
Your other link is research saying that statistic matters for fires. I can believe it does but your other graphs don't show fuel moisture as even slightly below average. Maybe the last two months of no rain indeed put fuel moisture well average. But, this is California - rainfall varies widely. LA has had many winters without rain, I grew up there.
I can't claim to climatological understanding of the situation. But I variety of narratives that don't make sense and impulse is to say that these are a response the LA fires being almost entirely a sudden and a unpredictable event, an effect not of trends but of the situation of global warming overall, something people simply don't want to admit.
