Is it still a 100-year event? Should start getting classified as yearly event now.

it’s up to the Government bodies (like NOAA and FEMA) to update their rainfall data/models, which is done via statistical analysis.

That being said, some states aren’t waiting around and are starting to require standards/regulations to meet their own updated/“future storm event” models. For example, in New Jersey stormwater design has to be updated, so any proposed roadway projects that were previously required to contain/handle something like the 25 year storm event now are required to meet the “Future 25-year storm event”.

That makes sense. At the very least, they should update their flood maps so new construction can't be done in these new flood prone areas.

Are they weighting the more recent data more strongly to account for the distributions to change in a given direction over time?
