There are over 2000 watersheds in the US. It would be unusual if we didn’t see around 20 100-year floods every year.


I would think they'd be correlated enough to mess up the numbers a little.


Right. It's the multiple-endpoints principle. The extreme events feel overly frequent because we cherry-pick and only notice them. We never notice the other 99/100 of places that don't have a hundred-year flood in a year.


Extreme precipitation events are also getting more common.
