Just wanted to elaborate on what a PMP is, and how it used.

PMP is probable maximum precipitation - which is an extreme rainfall intensity estimate. The probability of a PMP is often estimated as a 1 in 10 million year event or similar. However, many rainfall methods rely on using the PMP as an upper bound of rainfall intensity to estimate events rarer than the 1% annual exceedance event.

Therefore, this research may affect many structures, particularly those that are designed with extreme events in mind - which are typically larger dams and reservoirs.

This is a great example (one of many) of how it would have been cheaper to meet climate change mitigation goals. Think of the billions that will now need to be spent to update all of this infrastructure in coming years.
