Well, there are some reds appearing on the infrared images, so at least it is keeping up the thunderstorm activity. I agree Daniel, it does look better organised now than earlier.

It looks like the tower on the west side is here to stay. Click the link for a current view. Tops to 56,000ft at 08Z. Looks like it might get rough today.

Yeah, this system looks like it's setting itself up properly now. Let's see if it gets up to 30kts at the next advisory.

Still just a we bit heavy on the NW-SW-SE sides. Looks like a little drier air on the N side is interrupting the process. It's also losing some of the inflow bands it had earlier. Sunrise in about an hour. We shall see.

The latest adviosry puts the depression at 25kts again. Strong uper-level northeasterly flwo and subsidence over the northern sector of the circulation is likely to prevent significant intensification. Even so, it is still forecast to reach minimal tropical storm strength, so the watches are being left in place. Maybe the daytime heat will allow more convection to flare up and help the system become better organised.

From the 5am advisory/ discussion
WATER VAPOR ANIMATION INDICATES STRONG
UPPER-LEVEL NORTHEASTERLY FLOW AND SUBSIDENCE OVER THE NORTHERN
PART OF THE DEPRESSION'S CIRCULATION...WHICH SHOULD HINDER
SIGNIFICANT STRENGTHENING OF THE TROPICAL CYCLONE

Well agree with on the poor organisation of TD One. IR imagery loops show a centre located north of the area of deepest convection. also say the centre is elongated. Perhaps it is elongated because it is trying to relocate closer to the area of deep convection? Just a thought. Not really expecting a lot from this, but noticed shows intensification while it is overland. Also, it may just be a minimal Tropical Storm at landfall, which will probably be tonight.
Also think we could see the Wave in the Atlantic become something if it continues to organise too.

Here's a site I just located. The pix are done every 6 hours it appears. Lots of tools for enhancement of images. Click on the "Meteosat Images" button and then select the section of the sat shot.

Well SSD have upped the TNumbers for TD One from 1.5/2.0 at 0545 UTC to 2.0/2.0 at 1145 UTC. However, the visible satellite loops show that the centre remains exposed from the deep convection to the south. Not sure quite what the motion may be doing, as the visible loops arent that clear. Also, it looks like maybe the centre really is trying to pull in the convection to its south, but just cant fight the upper-level flow. Be interesting to see what the Recon flight finds.

I just checked and they have said that the centre is reforming nearer to the deep convection. Perhaps our friend has a shot at becoming Alex a little sooner than is being forecast.

could this impact TD1? looks to be moving north, and looks low level..... morning vis shows the spinning....east of outer banks of nc

looks like the center is of TD1 is reforming to the south near the complex of storms....... could Alex be on the way? The blow up this morning looks to be the best convection for this system since it has been in the atlantic..... Does anyone know where to get the recon message without using THC?

James,
further to what you said about saying the centre is reforming nearer the deep convection; the Vortex Data Message from the Recon flight has given a fix more than 1' further south than the 32.5'N given in the intermediate advisory at 12Z. This does indeed place the centre right on the northern edge of the deepest convection. As the circulation was earlier elongated, it could well be that there was more than one centre, or that the centre was trying to reform. However, the Vortex Message also shows winds at the surface no more than 30 mph, and a minimum extrapolated pressure of 1011 mb, 2 mb higher than stated in the 12Z advisory.
It will be interesting to see if relocate the centre in the 15z package, and also what impact this may have on the intensity forecast.
Oh, and SSD is the Satellite Services Division of NOAA. Their TNumbers and positions can be found HERE

I think the 11:00am update will be important for a couple of reasons: If they change the watches to warnings and/or if they move them south or north we will know that TD1 has a destination in mind.
Right now, it doesn't look promising to be our first named storm, but what the heck do I know anyway? I do know this: that the storms to our west are definitely building up and looking to the east you can see of the feathery looking clouds from TD#1. At least I think that's what they are.

looking at the latest goes-e vis....the center looks very exposed..... on close-up....center looks to have picked up a little forward due-north jog in the last few hours..... storms look to south look to be far from center.....
