I have only been following the tropics closely for a short while and I'm just a layperson, so I have a question for the moderators, mets, and anyone else with experience out there.

What's been the most confusing or unpredictable storm you can remember? How does Irene rate in this category? I have been astounded at how this thing has survived despite the odds and pretty much defied every forcecast up until now for both intensity and direction. It just seems to me one of the trickiest storms but it could be my ignorance talking.
