The water vapor loop did not show shear earlier today, which is the last time I looked at it.
Cloud tops have been oscillating in height it appears, but are still pretty high.
If there is a closed low, I'd say it's right near the big blowup of convection, too... meaning it's really only a matter of time before TD 7, and ultimately Gustav, is born.

Just read the 8pm TWO, and the NHC says there is no sign of a closed circulation at this time.
