Well, we got the big, new "donut-hole" eye last night, with "stadium
effect" appearance beginning to manifest. (Note how yesterday's smaller
eye morphed into a meso-curl inside the larger eye.) I don't think
there'll be anymore eyewall replacements now that this stable,
high-atmosphere-volume-processing eyewall is in place...at least not
until shear or land impact take their toll on the windfield.
In the past, I have noticed that large and energetic* hurricanes with
very expansive exhaust canopies can strengthen and "warp" the high
pressure regions around them to accomadate their existence; the stronger
high, in turn, has additional "muscle" to bulldoze pesky jet-streams at
far peripheries. Sometimes seen with west-Pac storms and rarely in the
Atlantic, on WV satellite this assumes the appearance of a westward-
moving hurricane preceded by a forward "bow-shock" (of high cirrus) and
trailing an exhaust "rat-tail" to the east (as if it were a curling
We're getting the rat-tail and bow-shock appearances. Check. Upper-low
over Bahammas and southern-Florida beginning to retrograde west ahead of
the hurricane. Check.
The 8/31/11am advisory discusses various models and their
northwest-turning projections, noting only a few models still aiming at
the keys. ....I'm actually wondering: How do we keep it off of *Cuba*?
