Before I go ahead and say this I should say that I feel horrible about the loss of life from Katrina and Rita and also am slightly pleased with the "artificial" shock they imposed. But that's not the main point. I wanted to point out that in many ways we are all very concerned with how hurricanes interact with the gulf area, so if a hurricane is in that general area i feel that there is the potential to overemphasize its chances of going north. Now two big storms did go through the oil producingparts of the gulf this season, but I think we should recognize how our various "lenses" may be colouring things.
At this point, it doesn't even have to get close to the U.S.  If a hurricane forms in the gulf, everything gets evacuated and shut down for two weeks just from the threat alone.
