Would there be any scientific reason why a hurricane might be more drawn to a geographical place like NO?
(Ready to be snickered at...)
Not really. SE LA does stick out into the GOM, so it's possible that more hurricanes would come near it thanks to that fact.
No, I don't think so. There are some very warm waters leading up to NO, so perhaps the storm might be funneled there... But that's just speculation on my part.
