Where I live in Texas, we had three “500 year” events in three consecutive years, with the last one probably closer to a 1000 or 10000 year event - more rainfall in one spot than anywhere else ever measured.
We’ll see how long that record holds (I’ll take the under on 1000 years).
There's probably many other 1 in a 1,000 year events that haven't happened in many thousands. It's really hard to reason about infrequent events, especially post-hoc.
