Once again, Skeet comes through!

I've noticed that most of the model animations that are being posted use the surface level pressures.
While these are fine in determining surface pressure and precipitation.
The Upper Air level animations should give a better idea of the vorticity, or spin, of the systems.
Try looking at the 850mb and 500mb level animations.
A tropical wave or depression would be visible in the 850mb levels.
Whereas a Cat 1 hurricane should extend into the 500mb levels and possibly into the 250mb level.
It will give you a better idea of the depth of the storm. 3-D if you will.
