Thats right which is exactly my point...you can't look at sat pictures and make a definitive statment like this is a 2 or 3. Bonnie had an eye and it didn;t show up...frances as an eye and it shows up but you can't say it is a 3 because it looks great. I bet Frnaces is a 2 or 3 within 24 hours or sooner thoughw hich will be confirmed by NHC.
I would of answered earlier but I had to go out today.
I think you misunderstand what I posted about. I'm simplying stating my opinon based on an observation. I'm not making a definitive statement, because I wasn't trying to prove it was a Cat 3. It looked like a Cat 3 this morning (and still believe it probably was then). Really, I was just stating that I thought it was intesifying.
There's no plane to go into the storm, so we now have just satellite images and estimates. The TPC upgraded it to Cat 2 this morning then a Cat 3. How do you think the TPC came to that conclusion without a plane in there?
You bring up Bonnie as an example but the fact is that Bonnie, never looked nearly as good as Frances has been looking today. And I'm sure if recon goes there will find an eye with more than 65mph winds.

Frances Eyewall
The last floater image looks like she is about to go through an eyewall replacement cycle. If so expect an eye with a much larger diameter by tomorrow morning.
Also an apparent jog to just north of west happened the last two frames...I hope this doesn't hold true.

Intensity duration of frances..
I have been seeing people compare the track of frances with andrew on here, but there is one major difference, the intensity. If I remember correctly, Andrew was a moderate TS when it started its turn back west. This thing is already a category 3. It might reach cat 5 in the next few days but just becuase it might be a cat 5, it doesnt mean it will stay that way. Maybe I am wrong though. Maybe conditions will be ripe for it to maintain a catastrophic intensity (if it even obtains it), but my question again is dont the systems kinda wear out, not that it wouldn't be a major storm still but just not cat 4/5. What is everyone's opinion?

Very true. Hurricanes are like fire. As long as they have fuel to keep them going (warm water, no shear, favorable UL conditions) they'll stay as strong as possible for as long as possible.
Cut off a hurricane's fuel (landfall, shear, etc.) and the hurricane will die.
The interesting thing of course is that extremely favorable conditions to support a Category 5 in the Atlantic Basin have never lasted longer than 3 days. Hurricane Dog in 1950 lasted as a Cat 5 for 60 hours.
In the Pacific Basin, super typhoons can usually last much longer since they have way more fuel.
