[Jyo_hurricane] Tropical Storm Jerry & other important blobs: September 24, Update A

Subtropical Storm Jerry aquired 'tropical characteristics' by the 11pm
advisory last night to become Tropical Storm Jerry. It was at a latitude
of about 37N, and over water temperatures of less than 26 deg C. As you
know, I disagree on naming this one in the first place so I won't even
begin to quibble over this designation. The deep convection continues to
remain minimal, and it did not reach persistent winds greater than 35 kt
(40 mph) all day yesterday (and even now), which is just 1 kt (1mph) above
the boundary between a T. Depression and a T. Storm. We had more deep
convective activity in the eastern Gulf and from Florida to Louisiana
yesterday than there was in this storm combined for the entire day.

Speaking of FL to LA - for a change, everyone but TX got rain yesterday.
:) It was a really impressive spread of activity with no real formation -
I quite enjoyed watching it on the satellite imagery. Looks like more
stuff (technical term) is heading for Louisiana today as well.

The other blobs.

1. There is some circulation at the lower level of the atmosphere just
east of the windward islands, at around 12N, 57W. It has some convection
with it, and is moving westward. It isn't very big so just something to
keep an eye on, especially once it enters the Caribbean.

2. The biggest blob (sounds like a sequel to "The Blob" - which, by the
way, is being remade yet again for release next year for the 50th
anniversary) is still out in the eastern/central Atlantic at ~10N, 30W.
This continues to have some impressive circulation for a system that is
still developing, as well as a large area of convection. At the moment it
looks like it will stay out in the Atlantic though.

More later I'm sure...
These remarks are just what I think/see regarding tropical storms - not
the opinion of any organization I represent. If you are making an
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.
