LI Phil, 92L is the wave off of Africa - TD 2 is the old 91L. Just wanted to clarify any confusion there.

As for Rabbit using the global models to forecast the fate of TD 2 - global models are notoriously inaccurate when it comes to tropical cyclone intensity. This can affect their position estimates as well. It takes a model like the GFDL or other intensity-based model to accurate gauge future intensity; the GFS, UKMET, etc. are all geared towards baroclinic dynamics and as such aren't going to accurately capture the near-barotropic nature of a tropical cyclone.

The best example of this is a 1000mb estimate of Isabel's central pressure last year by the GFS/AVN when it was a Cat 5 hurricane.
