I don't think that's likely, hurricanes always seem to be surrounded
by high pressure areas which keep them spaced out.
But when I looked today at the regional water vapor loop, I noticed
the same thing you did, that they're 'stacking up'.
Just like 05, one low pressure system right after another.
But I have to emphasize again what has changed in the last
few years. It's their size, the size of the eye is very important
to watch. Tropical storm Fay had an eye over a hundred
miles across, just like Katrina and Wilma and several
other recent storms. Remember, the eye shows how
much heat energy is stored. These storms are easily
two or three times as large as what is typical.
And that doesn't mean two or three times more
potential energy, the energy is squared, not multiplied as
the eye increases.
Look at the last radar image of Andrew, it's eye is
about the size of Miami.

Look at the eye of Wilma, almost the size of the ...state.

Both reached category 5, but they need to be in two entirely
different classes of storms imho. Global warming means
hurricanes are now normally the supers.
The large eye means a potential for rapid strengthing and
maximum speeds.
Wilma went from a 80 knot storm that was expected
to fall apart once it made landfall, to 135 knot monster
in ....THREE HOURS. And it did that overnight which is
rather unusual. One storm off the coast of Florida in 05
increased 3 categories in 90 minutes just as it approached
landfall.
And what this means is that landfall no longer means
the storm will quickly dissipate as is usual. Fay just crossed
Florida /three times/ without losing hardly any punch.
Now, landfall just pisses 'em off. And they're too large
and strengthen too quickly to run from them anymore.
New Orleans is already talking about a complete
evacuation from Gustav if it's follows the expected
path. The problem is they have to decide 72 hours
in advance.

That was just a baby at 160mph~
The southern eye wall of Hurricane Wilma passed 40 miles north
of my house.
"Hurricane Wilma was the most intense hurricane ever recorded
in the Atlantic basin. In a 30 hour period, the pressure dropped
from 982 mbar to the record-low of 882 mbar, while the winds
increased to 185 mph (300 km/h). Wilma was the twenty-second
storm, thirteenth hurricane, sixth major hurricane, and fourth
Category 5 hurricane of the record-breaking 2005 season"

This has happened a number of time this year. Check out the Meto data
on tropical cyclones.
They separate themselves out almost as if they are acoustic or light
waves. There is a sequence of similar things happening right now in
the North tlantic.
I postd a few charts of it on a MSN site I have had for a while:
http://groups.msn.com/Weatherlore/shoebox.msnw?action=ShowPhoto&PhotoID=12
I haven't sorted them out very well so check the charts for the dates
on their legend.
I have also been looking at their knock on seismic event which would
be a logical stage if they are acoustic in nature, would it not?
Pop over to sci.geo.earthquakes or alt.talk.weather. There is always
room for a little more cross posting on usenet.
Best retards.
