So let's see--that's an average recurrence of ~50 year--just about
that of Cat 3 or greater hurricanes, I think???


I note that Hurricane Charlie when it hit Port Charlotte in Florida,was a
Cat 4 hurricane,Andrew a few years ago was a Cat 5,and Katrina was a Cat 4.
That's THREE Cat3 hurricanes in less that 10 years.



Any wonder why lessons are forgotten so easily?


Forgotten?;they were never learned.
