A ‘megaflood’ in California could drop 100 inches of rain, scientists warn

From a previous discussion on here, there were major floods in the Central valley in 1950. There is a USGS report here including some impressive pictures of the flooding despite the poor image quality. https://pubs.er.usgs.gov/publication/wsp1137F
The flood was caused by a series of wet, warm storms without enough time for the watersheds to absorb the rain like the scenario described in the original link.
Article: "It already has happened in 1862, and it probably has happened about five times per millennium before that. On human time scales, 100 or 200 years sounds like a long time. But these are fairly regular occurrences."
Wikipedia on 1862 flood: "The event dumped an equivalent of 10 feet (3.0 m) of rainfall in California, in the form of rain and snow, over a period of 43 days."
I'm surprised I haven't heard of it before.
You're describing the Gambler's Fallacy.

California does not normally get a huge amount of rain even in the winter, but when it does the storms are massive.
The weather in California is getting increasingly unpredictable and dangerous. The state is experiencing more extreme weather patterns, with more droughts and more intense storms. This is causing major problems for Californians, who are struggling to adapt to the changing conditions.
