Check Out the SSM/I Microwave Imagery
85H imagery shows a very well defined mid-level center but it's difficlut to find a well-defined surface center in 37H imagery...check out this comparison from the 2317Z SSM/I pass. Because the links at NRL are so long...I created a new page to show the difference:

In other words Mike not the best organized system right now and the window of oportunity to strengen is closing.

However...for December...it's really well organized. LOL.

Agreed that for being december this looks more impressive than other TD's and TS like TD#6,Grace,Henri for example in the heart of the season.

I think the track will end up to the right of the most recent official forecast and probably end up putting the center over the western side of hispanola rather than going between the big rock and Cuba. Unfortunately...that spells a nasty rain and flood event for friends there...and the western side of your island could see some rain as well.
I would put the center at 20N 72W in 40 hours or so...and by then it should start to pick up some speed.
The GFS is close to the official forecast and is slower in kicking the storm out of the caribbean...and out of respect for the model...I'm not leaning even further east with the track. Remember Lenny a few years ago...all of the models wanted to turn it to a more northerly track and it stayed to the right of all of the guidance. Considering the initial motion is further east than before (55)...a left turn is going to have to happen very quickly for Odette to cut between Cuba and hispanola instead of going right over Hispanola.

And if that happens Puerto Rico may see more rain than expected because it would be a bit more closer and we dont want another rain event.

The 85H center is very impressive looking...no squabble there...and a better defined low center may be down there...but it isn't clear in the 37H imagery from 2317.
Actually...betcha $ they pretty much used the 85H fix interpolated a couple of hours for the initial position at 00Z. But it would be nice to see better curvature and or a better-defined blue spot in the 37H imagery. Conventional IR4 shows a pretty good burst near/over the 85H fix...so who knows?
I just wonder if the surface feature is broader. We'll find out about 7AM tomorrow.

I agree it's not well-defined, but it sure is better defined than non tropical storm Grace. Glad to see the NHC is coming to its senses and slowing the forward speed way down. First track had it well north of the DR at 21Z Friday - no way! There's not much chance Odette could deviate left of the current forecast track. So if the track is off, then a track farther east is more likely.
Still, Puerto Rico will probably miss out on anything but an isolated thunderstorm.
One other thing, the recon schedule may be for a 12Z departure (7am EST), but it's not going to be in the storm until around 18Z. So we won't have the full recon report until around 21Z (4pm EST) tomorrow.

I don't think the next fix is at 18Z. The POTD from today has Flight one making fixes at 12Z and 18Z tomorrow:

Taking off at 0630z Friday.

Just a quick SSMI update...the most recent pass missed, but the one from earlier still showed a good mid-level center...but not as tight as yesterday (see long link at bottom).
Interesting that recon reported that there wasn't much spiral to the radar presentation...which would lend some support to a good MLC and a less-defined surface circulation (but still obviously closed). Also, although an impressive QSCAT for sure...looks like (at least at 10Z this morning) there may be something amiss in the SE quad...although those are rain contaminated barbs.
Still...have to admit the system is very well organized overall.
