SHIPS doesn't really do anything with this system, the global models hint at weak development but not a lot else really, probably no more then a minimal S/TS.

Well the shear according to the SHIPS is pretty awful for a while yet so any development will probably be weak...still can't deny there is some decent model agreement on something spinning up.

Does't SHIPS use BAMM for track? Not much use at this latitude.

Wasn't the GFS the first to spin something up in this area when it was trying to curve Alex up the TX coast in previous runs?

this mornings ECM though did have some Vorticity with the region which 95L is in and took it westwards a little bit offshore, but no it didn't develop it into a TC.

The Canadian, brings it across Florida and nails Hatteras. Pound for pound the most entertaining model going.

Not to mention its going the wrong way on the CMC to what the steering currents suggest. Ole CMC not going to have its track verification stats if something does develop with a track like that.

The storm off Hatteras is not 95L. It's another system it develops coming off the Bahamas. Take a look here:

Look at the 850 vorticity field of CMC, what goes up the east coast is a different vort max. The vort max of 95L goes very weakly into NOLA.
