Make that the Atlantic basin since one is in the far SW GOM and not quite a named storm. 
*grins* Semantics...it's all semantics! But you are correct. Atlantic Basic is more accurate. I was just being lazy.
Speaking of unnamed storms, I'm rather suprised they actually called it a depression, I've seen much better looking systems go unnamed... what makes this one stand out, potential for development?

Looks like the center is reforming more toward the East in the latest vis sat pics. Still, the upper level outflow seems to be expanding toward the SE. To hard to tell if it's a distinct motion or just a result of some reorganization within the environment.

Could be the closed circulation coupled with the wind speed and pressure. They also noted the convection building near the COC.

No Keith, this is a stupid question (albeit one that has been bothering me)...
when a cyclone "loops" do the quadrants swap, so to speak? Otherwise, it would be going backwards. How does this work?

Not a stupid question 
your first instinct is correct, the quadrants are based on the direction the storm is moving, so if the storm is moving west, then the northwest side is the 'right front quadrant' if the storm is moving east, it's the southeast side that becomes the 'right front' quadrant.
Follow up question, what happens if the storm is stationary? which quadrant is which then? is it based on the last definate motion of the storm before it stalled, or do they just avoid using quadrants to make sure people don't get more confused?

the quads remain the same.. but the strongest winds are just located in a different part ot the storm.

Tropical Depression Seven Advisory Number 1
Statement as of 4:00 PM CDT on July 23, 2005
is now out. (And it's only 3:45 CDT lol)
Quote:
At 4 PM CDT...2100z...the center of Tropical Depression Seven was
located near latitude 19.4 north... longitude 93.2 west or about
180 miles... 290 km... west of Campeche Mexico and about 295
miles... 475 km...east-southeast of Tuxpan Mexico.
The depression is moving toward the west-northwest near 6 mph
... 9 km/hr...and this general motion...at a slightly faster forward
speed...is expected for the next 24 hours.
Maximum sustained winds are near 30 mph... 45 km/hr...with higher
gusts. Some strengthening is forecast during the next 24 hours...and
the depression could become a tropical storm by early Sunday.
The estimated minimum central pressure is 1011 mb...29.85 inches.
Looks like they think it's goin into Mexico but south of where Emily hit a few days ago...

I seriously need to learn to type faster than Keith!

I hope someone can help me out here. I've posted a lot but am obviously quite the newbie, and have not really understood what I have seen in the sat images for Franklin from practically day one, which is a little frustrating. I am trying very hard to read the sat images. So please tell me if this is correct.
I can see something spinning counterclockwise to the west over the FL and that is a low, right? Then to the N is some kind of boundary? It is less distinct now than some hours ago - what is that.
It looks like, where Franklin is, I am seeing two different layers of clouds spinning 'round instead of one, not exactly on top of each other. Why is that. How are folks determining where the center is and the direction, if this is the case. Is it a matter of being very skilled at looking at the sat images? Am I wrong in seeing what appears to be a move to the S for one layer of clouds and a move to the E for another lower layer?
At least I did see one thing - the transverse banding Clark was talking about. I looked it up on the web and then did see it on the sat image. I guess cirrus are the easiest clouds to recognise.

So, do I have this right? When came through it wasn't too bad here in Bradenton. When Jeanne came through we thought it was worse. Is that due to the flip/turn/loop? We were always on the south-west side of the storm, which usually isn't bad....but in the loop did that turn the "bad" side around?

Well Franklin's window to become a hurricane is winding down fast. The trof axis is digging, and dry air is already starting to be entrained. Unless the center reforms to the south and decouples under the outflow cloud mass, the storm will quickly lose it's intensity...

No; when Jeanne headed for Florida, it was moving towards the west, making the right side of motion -- the northern quadrant -- that favored for the strongest winds. Many factors can come into play once a storm hits land, however, including downdrafts and friction (to name two).
The direction with respect to the storm changes when the storm changes direction (e.g. right front, left front, and so on), usually leading to the strongest impacts of a storm being felt in whatever region is the right front region, but the actual quadrants themselves (NE, SE, SW, NW) of course do not change. Land complicates matters, as described above.

It is worth noting that the center of TD 7 that the is tracking is just along the northern shores of the Mexican coastline in the southern Bay of Campeche, currently lacking convection -- and not the larger cloud mass to the north and west. The whole region is an area of broad cyclonic turning, but they are tracking a center just along shore at this time. As the storm organizes, expect all of this to consolidate into a better defined system.
More tonight or tomorrow...
