It’s normal for LA to get less than 18” of rain in an entire year. The ground is harder to saturate when it’s been dry so long, which makes flooding more likely. And along the LA River we have a godawful concrete channel that doesn’t let any water get absorbed once it hits the culvert. Combine that with rain for the next week (up to 6” possible in some areas) and really big recent (<2 years) burn areas, we might also be getting mudslides on top of everything else.
