For the life of me, I can't see at all what MIA is seeing. I'm looking at a 11 hour loop, going forward and backward on it, and there is no semblance of a southward component to its motion at the end. The center gets difficult to ascertain as the radar presentation deteriorates, but it improves right at the end - still WNW from what I can see, with perhaps the occasional due westward wobble.

I'll be updating the SJU loop in a few...

If it had truly been 1007mb they would have explained why instead of just stating it.

I know just about enough to sound like I know what I'm talking about sometimes. But for your safety please follow the nhc for truly professional forecasting. :D

they have the system as an "L" by the time it reaches the tx/la coast...does that mean they think it will weaken as closes in on the coast?


Here is the 7 day loop.

http://www.hpc.ncep.noaa.gov/basicwx/day0-7loop.html


They follow the NHC, their forecast only goes through 5 days. After that they just keep it a low.

Hmmm

I guess all the models and forecasts indicate a more west ward turn about 23N. check out the 1016mb line

24 hrs http://www.nhc.noaa.gov/tafb_latest/atlsfc24_latestBW.gif

72 hrs http://www.nhc.noaa.gov/tafb_latest/atlsfc72_latestBW.gif

We've seen it happen before but, but it still seems like a pretty steep left turn out 72 hours.

They should be hitting the center in the next dataset, which should be out in the next 4 minutes or so . . . as to the actual VDM, that could be anywhere from 5 to 15 minutes out by my guess.

Highest FL wind hasn't been impressive . . . something like 56kts I think, but you'd have to check back (page 2/3 area) to be sure of it . . .

It seems that the storm is right on the Trop Fcst Pts the NHC has on its sat shots?

AHA! The missing dataset is in.

EDIT: StormsAhead beat me to it. And that's an old VDM, dixie.

Could be, my comment was directed toward the WSW radar-based motion. Just don't see it at all.
