I took this out of the old 91L thread and reposted it here. I can edit it out if necessary.

Giving this area another look tonight I have decided to agree with Hyperstorm. Currently the area is under sheared conditions due to Florence. However this system will not be able to make it east far enough to go through the same weakness that Florence is going through.
Current shear tendencies can be seen here.

Florence is currently appears to be slowing down a bit due to the fact that she is moving towards the SW periphery of the Ridge.
But, as Florence speeds up this area will have to be watched. I don't think the models are picking up on this right now because it is so weak. As Florence moves farther and farther north away from it... shear should relax enough (if it's still there) to allow it to be able to fire up up with covection.
Part of the reason I am worried about this system a little is because as Florence pulls out with the Trough the weakness in the Ridge will close and this system (barring it's there) will be left behind.
Below you can see the 500mb forecast from GFS @ 18Z. It depicts Flo moving our and the ridge closign the gap to the south. Also you can see from the 250 wind/hghts forecast below, the westerlies will be far enough north not to affect this system.
GFS is also forecasting a rather large upper level low to develop but, this area should be far enough to the east to not be significantly impacted from it's effects.

So we'll see... I think this may end up being a threat to the US or the GOM as any approaching troughs may draw the system up farther north but, by that time it will be close enough to probably affect the US ....
If, if if... it holds together.
