Well, there ya go! According to the NRL website, Invest 99L has organized sufficiently to lower the central pressure enough to increase the sustained winds to at least 30 Kts. and Viola! Tropical Depression 8 has made its' presence known.

I expect official advisories and forecasts from the NHC to be issued in 1/2 hour, or 5pm EDT. At this rate, it seems entirely reasonable to speculate that TD8 will become TS 'Grace' within the next 12 to 24 hours, before the upper level shear ticks up a notch or two. NHC dissipates the system in a few days due to strong shear, but who knows? If a decent low and/or mid level circulation persists, it could very well find itself in a more conducive environment by days 4 or 5, in which case regeneration is certainly not out of the realm of possibilities.

Certainly the most interesting thing (Western Pacific not included ... more on that later) that we've seen in quite some time!
