Adding water vapor to the physics of Isaac will drive the velocity of the storm. Right now the oscillation is driven between sucking up water vapor and using calories to increase velocity.
The latest turbulence in the Gulf I mentioned yesterday was drawn into Isaac's physics. It can be noted in the 12 hour loop. That storm is hungry for water vapor because it is not finding it where Earth currently has it, which in the upper troposphere. This is a water vapor satellite and according to what is visibly in the troposphere Isaac should not be this challenged to build velocity, but, it is. The water vapor at the altitude where Isaac lives is sparse.
There is a third potential for a storm in the Pacific that has existed for about 2130 on August 23rd. It may have sustaining effect on the trajectory of Isaac as Joyce in the Atlantic still does.

Isaac is still dependent on direct solar rays. The Pacific system organized quickly in 13 hours.

Isaac likes it's water vapor. It moved back to the south. The reporting in bold is where I last noted it's activity. It is oscillating and building strength with every spin of the clouds. The central pressure in italics is still dropping. Isaac isn't finished building strength yet.
It is dropping central pressure, but, not speed. It is reorganizing where it finds water vapor.
