The best answer to your question is in the NHC Forecast Discussion here:

https://www.nhc.noaa.gov/text/refresh/MIATCDAT4+shtml/131455.shtml

Due to a lack of a well-defined center, the initial motion is highly
uncertain. It appears that there has been little motion during
the past few hours. A weakness in the ridge over the western
Atlantic is forecast to develop and this pattern should steer the
system slowly toward the northwest and then northward. In about 3
days, an eastward moving mid-latitude trough will force the system
to recurve away from the coast toward the Atlantic. The guidance
has shifted a little to east this morning and consequently the NHC
track forecast was adjusted in that direction. However, the official
forecast is still on the western edge of the guidance envelope. If
the disturbance develops a little more to the east, the track
forecast will probably adjusted to the right later today.


Anything more is conjecture at this point. The NHC track and forecast discussion will be updated at 5pm. That is really the best, most reliable source for up to date information.

Southern Vort is starting to bottom out. which means the northern vort should begin to swing west.

It looks like that's where the MLC is at but I don't think that recon found it closed off at low levels.
It appears to be still quite elongated out to the southwest.
Someone correct me if I'm wrong.

over the next several hours. the circ that has developed in the convection will likely become expose and shoot west while the one to the south rotates back east.

the southern vort is going to take on a lot of energy while the north one will lose some... Convection will build over the southern one as well.

Assuming the southern one does not stretch out.

that will be interesting to see that unfold. Thank you for your continued skilled observations and input!

So, does this mean the main center is, indeed, forming east?

With it slowing down again can that change the path?

Weather for me this weekend. Partly cloudy,breezy with a chance of a shower. Don't think much effect from this disturbance for me. But the season only starting second half. :eek:

Well as it stands now the bulk of the convection is even east of the Bahamas

True - the main effects could very well miss the Bahamas and stay well south of Bermuda.

Correct. The rightward trend benefits not only the conus but them as well. Efforts to back yard shame someone for pointing out positive trends are tiresome. The obligatory walking on eggshells mentality after a big hit reduces the inclination of people to participate at a time when social media is depleting needed oxygen from specialty forums. I find it regrettable.

looks to me like the naked swirl is right over exuma island, at least I think its that island. The mid level one is to the NE, this storm is still getting sheared alot.

Two vorts, thought the northern one might stay with the convection and dominate but doesn't look like that will happen. I'm not even looking at the models till this settles down.
