I was wondering too, my best guess would be an upcoming ERC, but I can't know for sure.

Hey...stick a sock in that kind of talk. The GFDL takes it right into my favorite fishing hole as a Cat 5.

Do you realize how that is going to mess up the flounder run? :lol:


Yeah and it also kills my place.

OK guys - I am seeing a tail off of Dean - could it be separating and the possible of a separate cane behind Dean due to the condition in the Caribbean - not trying to wishcast - just wanting answer the the convection coming off

Anyway you could post that? Or at least a link? I'd love to see that.


How do I put an image on here?

There has never been a second cane spin off an existing cane.

Hi. New here. I just found this site thought some people might be interested in it. Tells what storms have hit Kingston, Jamaica over the years and so on.

I think they are talking about the wave in the Atlantic.

Dean looks west still as far as I can tell from satellite and radar.

you have got to be kidding me. I for one think unless he's already en route to Jamaica, he won't make it there before airport closes TOMORROW.

I know that it is has never happened but look at the satelite. WHo, if anyone , can tell me why? BEcause I did not see it in Wilma, Rita or Katrina which built to this strength

About 45 minutes ago they showed a graphic saying that he would start reporting from there tomorrow.

Shelby, are you talking about the area of storms to the lower right of Dean?

See here for the picture I'm looking at:
http://resize.wunderground.com/cgi-bin/ ... &height=76

I think it's just a line of squalls embedded in the storm's outflow.

There is also another wave behind Dean in the Eastern Atlantic, but that's got nothing to do with Dean.

Oops. sorry. here's a bigger version of the picture:

mgpetre wrote:I guess in that vein of my question I was just saying that at the point that solar flares matter then we have definately gotten the models down to a science. I appreciate the very verbose and informative answer. Are you saying that a certain amount of storm history is put into the model on initialization? I think that would definately be a key to an accurate forecast. What about the question of how far-reaching are the parameters? I see a global model outperforming a localized one for obvious reasons. Again, thank you Wthrman13.


Ah, good questions. To answer the first one, if I understand you correctly, yes, a certain amount of atmospheric history is inherent in the initialization, since the "first guess" field comes from a prior prediction from the same model. For example, in the case of the 0Z GFS (it's actually a bit more complicated than this, but this will suffice by way of illustration), the first guess field is a 6 hour prediction from the previous GFS run (18Z, in this case). The real-world data that is valid at or near 0Z is then blended with this first guess state, to produce the 0Z initial fields. The model is then stepped forward in time from this initialization, and so on. There are other, even more sophisticated techniques out there to initialize models, but this is the basic idea.

To answer your second question, limited area models, such as the NAM, generally are "nested" within a global model, so that the boundaries are continually forced from outside by the solution of the global model. In the case of the NAM, the GFS provides the boundary conditions, but the interior model prediction is entirely the NAM. Typically, the local, or regional model will be designed to run at a higher resolution (more detail) than the global model, so it typically will perform better than the global in that particular region, but not always. Otherwise, there would be little point to running regional or local models.

Thats a feeder band. No chance of tropical cyclone formation because of the shear the hurricanes LLC is putting with in the area. That is why when two systems get to close to each other the weaker one dies.

Interesting thought...THe 5 AM track will feature a landfall point, possibly on the US/MX or even more north. That will REALLY put the media hounds on it...are we ready to hear "Dean eye's texas for the next 5 days''. On a serious note...the 5 am will be the most important advisory yet for the US gulf coast. I imagine the NHC will be thinking long and hard about where to put that dot.

I can only imagine how heavy their hearts where when they had to finally put that Katrina dot on New Orleans.
