There’s lots of chatter now that latest models have shifted LF guidance about 30 miles West.  But didn’t these runs initialize with a 20 to 30 mile westerly offset ? 

Looks like tighter clusters mostly but many of the more western tracks show the cane moving NNW starting now or even should have by now. Time will tell.

You are absolutely correct.  I stand corrected.  

But your point is still a good one. No major in that region in 73 years means increased vulnerability if a major were to hit there.

It’s trying. 

Indeed, finally seeing a consistent burst of deep convection and it appears that deep convection is wrapping the core now. Marketable improvements upshear, I suspect what is happening now is that column is trying to get vertical which should happen very soon, once it clears Cuba.

IMO...the environment ahead is the best environment an Atlantic tropical system has had since Michael. All systems are go, once it clears Cuba, for RI. Some indication I seen in previous runs of the COAMPS that suggests a potential period of explosive intensification once it gets over the loop current tomorrow afternoon.

From the looks of things Idalia is getting ready to launch.  Satellite and radar looking quite impressive.  Idalia is just getting ready to cross into the southern GOM.  I said about 36 hours ago if she can have a core established by that time the stronger solutions will play out.  Looks to be entering the GOM as an intensifying Tropical Cyclone.  Once she center clears western Cuba I think we are going to be in for a show.  Also, IMO I think the nudges westward in the track guidance are over.  Looking at WV loop the small upper low over the FL Panhandle is moving east and lifting out.  Idalia should follow in that general direction as upper trof dropping through the GL/Upper Ohio Valley eventually takes over the shunts her east off SC/NC coast.  Landfall I believe is 25 miles either side of Cedar Key.  No doubt in my mind though that the lid is going to come off the pot soon.

I see some limiting factors on the water vapor map dry air north of the Yucatan and also an area of shear moving SE with the upper level low over the NE Gulf sliding south.  I am wondering if the dry air to the west keeps things in check a bit and the upper air low over the NE Gulf forces Idalia further southeast track but on a NE trajectory towards say Sarasota to Tarpon Springs area guess time will tell.

Thinking along same lines on possible adjustment to the right in track and for the same reason you mentioned, though not thinking as far to the right as Sarasota.  Pine Island maybe?  IMO not concerned about any dry air, atmosphere looks moist ahead (especially if track is more to the right) and if there is some dry air entrained from the SW it should be able to get mixed out quickly with increasingly favorable jet divergence aloft.

I have trouble seeing how Idalia would get past that line I drew on the map, especially as the upper level feature in the Eastern Gulf moves along.

The question is does it miss the trough... As it strengthens and remains in weak steering currents... I would think that this is a real possibility.

Even if the models prove accurate, Idalia’s strongest winds by far are in the SE quadrant presently.  I can’t imagine a scenario where Tampa Bay region avoids seriously damaging surge as it moves toward the big bend or even Tallahassee

I see you are in Tampa. I would personally prepare for the worst and make plans in case it looks like you need to move further inland. While I personally do not believe this will be the case, it would be foolish -in my opinion- not to be ready in case something like this took place. 

One just need remember Charley in 2004.

And should stay that way, particularly near landfall when sw shear picks up. Saw mention of potential for halfcane or oddly shaped presentation.

I'm still reeling from the GFS and ensembles bust from last year taking Ian to the panhandle instead of Sanibel/Captiva. Whether it's Hurricane Irene 1999, Hurricane Charley 2004, Hurricane Ian 2022, they always seem to move eastward as they are influenced by the trough in the Eastern Gulf of Mexico.

Seems to be the case more often than not.
