13.5N 47W is about where I would peg the old 98L and yes, I was just getting around to posting on this, myself -- I do believe that the combined synergy of shear from the upper-level trof to Six's north, and a still relatively intact 98L to it's southwest, has really taken a bite out of Six today. Meanwhile, in response to a weakening Six -- and also having the benefit of far less shear, 98L appears to be staging a comeback. If current trends continue I would say that 98L has a fair chance of TCing by sunrise.
Six very nearly devolved into a wave this afternoon, despite an earlier appearance of a marginal TS and Current Intensities of 2.5 from just about all if not all agencies (as far as I have checked so far, Six did attain 2.5 from them all at one point). I was so very close to writing Six off for the evening (with the knowledge that it could revive, of course) when all of the sudden we are getting a blowup of deep convection near it's center -- which, I would still have to say is north of where NHC pegs it to be --- again, Six has had multiple cocs over the course of it's existence, but you can't really say that 98L is one of them. 98L is it's own entity --- frankly, 98L has been a weak, sub-TD tropical cyclone, already. I say sub-TD tropical cyclone, because it certainly wasn't a wave, has had a surface cyclone all along (and pressure estimated to be about 1008mb) and winds in the 20-25mph range. Just sub TD status, but then got upstaged and interrupted by 90.
Moving on to some other features - the feature to the east of 90L really should have been tagged as 91 for some time now, imho. At least NHC does mention that some slow development is possible with this Low. Additional slow development may also occur with the grab bag of features in the Gulf of Mexico/northwestern Caribbean. Have two surface trofs interacting with various waves and all getting some kick from a stationary ULL that is just weak-enough as to not be producing hellacious shear -- shear just barely low enough to perhaps allow slow tropical cyclogenesis to take place.
