UNISYS Water Vapor GOES East Satellite (click title to entry for 12 hour loop)
The water vapor currently feeding Isaac extends from southern Florida, USA, NA to southern Columbia, SA.
It is that huge and actually increasing in velocity. Never thought it could reach that far in diameter and expect it to increase in velocity before it reorganized. It is reorganizing now. That is a gigantic water vapor field.
Earth never ceases to amaze me. When I think Earth's water vapor has reached it's limit it proves to be more amazing than before.
12A 16.90 -69.40 08/24/06Z 40 1001 TROPICAL STORM
Nearly an entire degree difference (.8) while dropping a millibar.

The central pressure remained stable while the position of the storm moved in smaller increments.
A half degree oscillation while falling 3 millibars.
14A 16.80 -71.40 08/24/18Z 50 997 TROPICAL STORM
A near half degree oscillation (.4) while falling another 3 millibars.15 17.20 -71.90 08/24/21Z 55 994 TROPICAL STORM
Fairly stabilized in latitude, it spun its huge reach another 5 knots and dropped another 2 millibars.
15A 17.30 -72.00 08/25/00Z 55 992 TROPICAL STORM
Oscillation is the way these storms find their power. They need water vapor. I had no idea Earth's physics would allow this this size storm. Wow. It is a hot planet.
The oscillation is easily noted with its latitude. Issac's progression west is fairly consistent, but, the latitude continues to wobble from higher to lower to higher. It is the size of the water vapor field that causes that.
I left off at location 13, 40 mph with a central pressure of 1000 millibars.The storm is very quickly becoming a major storm. It dropped its central pressure 8 millibars in 9 hours. It has traveled west by 2 degrees and north by 1.3 degrees; now at 55 mph. Unbelievable considering the size of the water vapor field.
Cuba Weather (click here for loop)
I was looking for Air Pressure readings in some wide bands. I thought Cuba might reflect a fall in air pressure and if there was a sincere decrease to lend information toward the storms movement, but, there are no air pressure records noted on the net as of right now. I think if there air pressure under the bands are seeing significant falls and sustained falls it would be an indication of the direction Isaac is taking. If the air pressure is after falling briefly (approximately six to nine hours) it would indicate an oscillation rather than a movement of the low pressure. That is what I was looking for, but, it is not proven scientifically to be proven. But, it can be discerned. The storm is not completely loose of its physics.
There is also vortices in the northern reach of the troposphere in this hemisphere. They are starting to lie up like a vortex street. It is easier to see in a hemispheric view.

The air mass at the border between Canada and North America has air piling up and forming vortices. It has the structure of a forming vortex street. It prove to form a stable air mass keeping Isaac at bay.
Issac's stability will probably be realized within the next six hours and its path determined.
Good night.
