No more complaints from me about these never-ending winds from Frances.

Ivan is breaking records already.

What might/could possibly help to lessen the strength, besides hitting mountains?

shear and land.....either one could weaken him.......or if he missed the steering currents and sunk southwest...

for the US there are more hopes than the leewards.....cuba/hispanolia/haiti could weaken the storm considerably....also there is a chance of a trough saving the us altogether.

If this isn't rapid intensification, I don't know what is. Pressure is down 39 mb since then(estimated).

Two thoughts. Even if he is weakened from haiti and cuba, what's stopping him from intensifying rapidly again? Like starting over. SSTs are warm, low shear, etc. Second, does the windfield expand over time for a storm if it iis over water for a long period of time, or does it tend to stay compact if it starts out that way?
