Some very startling data has come out the past couple days.
1) The central pressure at landfall (946mb) was about equal to the Long
Island Express storm of 1938 +/- a milli-bar depending on where measured
and by which instrument.
2) Sandy's deepest central pressure occurred Monday afternoon just
before landfall and was only 0.03" higher than the all time far north
Atlantic record (North of Cape Hatteras), Gladys in 1977...which was a
Cat 4 storm and didn't strike land. (Sandy was far from the deepest
ever Atlantic storm however which was 886mb...or about 26.00".)
3) The IKE storm energy potential scale, a more detailed assessment of
energy potential and release revealed Sandy expelled more energy than
all tropical storms in recent history except Isabel in 2003. The total
energy output exceeded storms the likes of Gilbert, Andrew and Katrina
due to it's massively large wind field. The IKE scale is a very
different calculation than the commonly known Saffir-Simpson wind speed
scale and is one emergency managers and those charged with preparing for
emergency response should bear watching for increase forecast use.
What made this storm so different is the tropical force winds extended
some 500 miles from the center. In comparison, Katrinia's storm force
winds only extended about 150 miles.
I've attached this URL of the Yahoo post since the Washington Post blog
version has some scum trying to load either video or something that I
didn't care to wait and see. There is a link in the below referenced
article for the actual blog for those who wish to read it.

Using this metric, one could argue with some level of validity, this was
"THE" bad one everyone was fearing. A perfect storm. But didn't bear
one EAS message.
