Joe B...Two Areas to Watch Closely
Joe B is talking development in the Bahamas and S GOM over the weekend. Yes this stems from Invest 90 and the explosive convect in the SW Caribbean. The models indicate the distrubance in the SW Caribbean will move into the GOM toward Brownsville. The Bahama system may become stationary and wait around before moving N or NE.
I must say both systems look quite interesting especially Invest 90.

Yes, I think the models will eventually catch on if they haven't
already.

I hope he is wrong for the sake of residents in STX/NEMX. That area would be devastated if another strong system moved into the area so soon after Emily.

It seems to me that the piece in the Carribean is going to suffer too much from being over land in Central America. It may move northwest to the BOC, but it's going to be just a diffuse mess when it gets there.
The wave over the Bahamas is a tougher call, as far as I'm concerned. The GFS has it picked up by the shallow trough which is about to come through the east. But if the model is up to its old games of underestimating the ridge, then that connection could be missed, and this might have opportunity to develop and affect some portion of Florida or the east coast.
In favor of recurvature offshore is the fact that the center (to the extent there is anything one could call a center) is farther north than last night's setup suggested it would be. That improves the chance of a connection being made.
I said yesterday that they shouldn't bother with recon if there isn't an LLC by this morning, but I've reconsidered that. I think at least one flight into this thing is warranted.

It looks that way but I'm not 100% sure.

You can't just watch the cloud tops. There's strong upper-level divergence which is causing that big flare-up, but the wave axis is largely over land SW of there. The wave os propagating WNW, or maybe NW.

I don't know Jan looks to me that the SW Carib action has to go NNW or N.If that happen then 90L brushes the Carolina's would be my guess.There appears to be a TUTT like feature digging into the BOC,the SW Carib feature has to go N.The TUTT could I guess get cut off in time and turn into an ULL thus in time sending the Carib feature NW.

Lower/mid/upper?
They were saying upper just yesterday.

If it's gonna be here by Monday then it won't have much time to develope at all.

That was an interesting video Kat. I like Joe's description on the GFS not sensing the energy yet but perhaps seeing the pattern at 200mb and 500mb. So if the teleconnection between the WPAC tropical storm (moving very slowly) indicates anything for 90L, it well could get stuck out there off the east coast of Florida waiting for the steering currents to nudge it along one way or the other. One thing I think I've learned so far this season is that some July storms don't seem to be in a hurry to get anywhere. They move over water but go pretty slow once in land. Dennis was amazing the way it just sat over southern Illinois for days until a piece sheared off SW through Texas and Mexico and the other piece went off the NE Coast and Canadian Maritimes to develop what might be the lowest NAO values in a LONG LONG time. Check out the progs for the NAO over the next 15 days. I'm not sure we saw values that low in over a year (though I didn't go back and check the hindcasts).

A low NAO = "Go time" for tropical development. The 15 day forecast shows it tanking pretty deep in the negative.

Andrew '92, Katrina '05, Gustav '08, Isaac '12, Ida '21...and countless other lesser landfalling storms whose names have been eclipsed by "The Big Ones".
