The Blobette and the Blob: September 25 Update A

Now that we are approaching the last couple of months of the 'Atlantic
hurricane season' we can expect storms to sprout up in the western
Atlantic/ Caribbean/ Gulf. And indeed, there have been some interesting
sparks. I've been watching and waiting all day to see what would happen
... not much development tropically, although the economy is still
experiencing some stormy weather, and we do have another 6 or so weeks
before the peak of the political season. :)

The Blobette:
There's an area of circulation that grew a wee bit today, off the east
coast of the US. If you are anywhere from Florida to N. Carolina and it's
been a bit blustery, this Blobette is connected. Although the circulation
is centered SE of Wilmington (North Carolina - for those who were
wondering) at around 32.5N, 74.7W , it is part of a broader region of
vorticity (circulation) that spans most of the SE US coast. There was some
convection in the system this morning but during the day it has been
entraining dry air, so really all we have is some windy weather. There is
a chance this could change as the system is centered close to the Gulf
Stream, but that dry air is quite prevalent at the moment. It looks like
the center is moving WNW (ish) and into cooler water. They are sending in
planes quite frequently (or so it seems) to make sure it doesn't do
something sneaky like develop when no-one is watching (because we know
that never happens). With such vigilance, I think I'll just sit back, have
a cup of tea and keep an eye on it for now (just the one eye mind you). I
hope you surfers are having a jolly good time out there :)

The Blob:
Whilst I'm here I might as well give you an update on the Blob that was
dumping rain on the VIs/PR/Hispaniola region in the northern Caribbean a
couple of days ago. This has weakened - there is still some low-level
vorticity (circulation) in the atmosphere and some winds, but convection
has decreased considerably... and it looks like a er well... a Blob
actually :). It is now north of the islands and appears to be drifting
into the Atlantic.

"For never was a story of more slobs
Than this of the Blobette and her Blob"

Hmm... not *quite* Shakespeare. I'll just go and work on that line a bit
more shall I?

If there's any development I'll send out an update.

evacuation decision, please heed your local emergency management and the
National Hurricane Center's official forecast and the National Weather
Service announcements. This is not an official forecast. If I "run away,
run away" (Monty Python), I'll let you know.
