One rather strange thing about Polo is despite multiple ERCs/structural changes it remains a relatively compact hurricane. In fact the code has remained roughly the same size throughout its life
I was just nothing how over the last 15 years or so there has been a marked shift in first 40s occuring later, normally not until October vs before then when mid to late September was more common
Below is number of years with a SEP/AUG first 40s low for each 10 year period
66-75 9
75-85 8
86-95 10
96-05 6
06-15 4
16-25 3
I don't think it's hyperbole to say that all time US records for rainfall could be broken, with the slow movement, size/strength, track and of course terrain enhancement
