My wife was speculating that the massive Tonga eruption may have been the reason why California went from drought to flooding. Also, so far this Summer has been unusually cold here. I now that weather doesn't equal claimant, and that there are many variables that make the weather happen, but this one seems plausible to me.
Edit: There are articles that claim that the
opposite of cooling would happen due to water entering the atmosphere from the Tonga eruption. This article doesn't mention rain, but I could see how massive amounts of water in the atmosphere could seed more rain on the Western coast of North America. It's obvious we don't quite understand this stuff yet.
