TLDR; high potential for a very wet monsoon season in the Southwest and significant snow pack in the Sierras in the winter.
Ah, you are a fellow Weather West follower. (I’ve followed Daniel for years since, if I recall correctly, he was a student at UCD.)
For those who haven’t read the link yet, the gist of it is that it is now extremely likely that this winter’s El Niño event will be very strong and quite possibly historic. That has climate implications all over the US and across the world. If you are a bit of a weather geek, you should read this… and probably follow Weather West.
While it might seem obvious, "too much rain, too quickly," at it's more or most extreme can be catastrophic. Flooding on large scales, road and highway damage that could take years to recover from. Even "dry" monsoonal thunderstorms lead to dry lightning fires. (Like Big Sur, Highway 1 closed through for 3 some years, the southern California desert areas still recovering and continuing road closures after the 2023 Hurricane Hillary event - Death Valley national Park alone had 400 miles of destroyed or damaged roads.)
