Good Morning Folk and nice "catch" SW....Incredibly low shear in the Carribean is right......I thought that 92L would have gotten a better grove on by now but I am most surprised by the fact that it reamins nearly stationary since yesterday.....Forget the model guidance on this one for now; it could really almost go anywhere once it gets going but where is anyone's guess at the moment....Igor looking real good this AM and have to see where the ridging sets up over the next several days. Could be a fish as currently suggested by the models, or, some ridging could build back....It's all about the timing of ridging and trofs down the road.
Oh, Happy Peak of the Season Day Everyone......So far so good for CONUS but it's a watch and wait for now on 92 and Igor....Nothing else out there at the moment.

6Z HWRF on 92L.
Morning Storm......Looking at the loops it does appear that 92L has "detached" from the ITCZ but a really slow burn at the moment.
Looking at 92L...looks to be moving just north of west.

Still needs some work too do...I expect Tropical Depression #12 tomorrow
...
Today's the peak of the hurricane season
Well, that's it, season's a bust!
I kid, I kid...
Last report said he was on the corner of Bourbon and Toulouse laid out on the sidewalk - had a beer in one hand, a shrimps in da other one and a big grin on his face! ;)
...who dat?
Not liking those runs. Good thing there is at least 20 or 30 more.
However, they don't seem to be as confident with IGOR's recurvature. GFDL just kinda hangs it there with no appreciable gain in latitude at the end of the run. Of note, 92L is present ahead of IGOR in both models.
LMAO!

Does that mean this is once again similar to a West Pac typhoon, Senior?
Morning...You are correct but I don't quite understand the concept....Best explanation I saw on here was from Kman last year and it had to do with the preveiling westerlies and such and a few other other factors......Most viable storms already hit this area as a TS, or, don't develop until further west in this area (or get ripped apart by Hispanola if they remain weak in this general area).
Well those model runs show a potential problem; but I guess in that environment any direction is possible.
