From Florence-4 on our trading forum:
Wettest ever tropical system for North Carolina since 1950:

This is going to put Florence in the top wettest tropical systems in the US.............since 1950. 68 years worth of records is actually not a very long time for weather records. For instance, half of the state high temperature records in the US were set in the 1930's. If the cut off was 1950, recent records would be the "hottest ever".
Looks like Florence will make #8 on the list below.

How much rain would have fallen if not for the "climate change" or "global warming" contribution from the warmer atmosphere and oceans?
We can estimate that an additional 5% more H2O was packed into the saturated air mass(+5% precipitable water). If we round off the record amount to 34 inches and multiply it by 5%, we get 1.7 inches. Let's round that up to 2 inches of extra rain, so the amount without global warming, theoretically would have been around 32 inches.
So theoretically, taking out the contribution from climate change/global warming would have dropped Florence from 8th place on the list above, down to..............8th place.........the same.
It would still have easily broken the state record for North Carolina, slightly warmer atmosphere or not.
